Posted	Aqua one - HELP !!!!!
12-08-2006 22:46 by Jo Mack	Hia, I have purchased an Aqua one AR620 (possibly a mistake) which came with no instructions, I have tried to download these from Aqua one's website but the instructions for the 620 are for Aqua style 620 which seems to be a different model. Could someone please talk me through step by step what order the sponges, noodles etc should be in in the two chambers and whether anything should be under the brown plastic grill thingy. I think I may have got it wrong as the water is still a bit cloudy after 10 days. Any other info about this tank would be greatly appreciated. Thanks a million, Jo Mac.
12-08-2006 22:51 by Lexter	i had one of these i think but was a 620T (for tall) does it have the filter at top of the tank, running alongside the top???
13-08-2006 00:00 by Jo Mack	hia, yes it has a filter at the top accross the back of the tank with two chambers. There is a bar going accros the first chamber with holes in, the water comes through the holes into the first chamber then runs into the second chamber. There are ceramic noodles and a black and white sponge that go in the first chamber and a black and white sponge and some bags of carbon that go into the second chamber. Unfortunately, I don't know which order to put them all in. Oh yes, both chambers have plastic grills at the bottom. The water has a white haze about it that I can't shift even after putting in a fluval filter that I had from my old tank. Any ideas?
13-08-2006 00:53 by Lexter	yes its the one i had, its a nightmare trying to get info for those tanks on net, almost like they dont exist lovely tanks though i would worry too much about the order stuff goes in, most peeps dont even use carbon in their tanks the white ceramic rings are the most important parts, WORD OF WARNING, the filtration system on that tank take AGES to mature and cycle, how many fish you got in that tnak and how big are they, you are best "cycling" that tank for about 6-8 weeks, only having a couple of fish in it. If you already have it stocked up you will need additional filtration like you already doing, i found even when that filter is FULLY MATURE you still cant stock that tank too much, or you will need additional filtration, which is a shame coz it defeats the point of having a rather cool filter tray at the top of tank which it does have when i had mine i used filter spounge at the top and the ceramic rings, i think that tank new comes with "phosphate reducing" filter media which i think is b*lloc*s to be honest, as i said the ceramic RINGS are the most important part of your filter system
13-08-2006 00:54 by Lexter	sorry typo, i WOULD NOT worry too much about the order the filter media goes in the compartments, i mean try and get it right but it shouldnt be the end of the world if its in wrong order BUT i would personally ditch the carbon in the long run for purely BIOLOGICAL filtration as the amount of media in that tank is not sufficient for a good stock of fish in the long run
13-08-2006 01:09 by Lexter	sorry to harp on, i might be wrong, you might have different media but when i had my 620T (which has same media as your as far as i know) about 33% of the filter media was made up of a pouch that is for "phosphate reducing", total waste of space as a filter medium i thought, ditched it and replaced it with MATURE fluval filter spounge after a couple of months, this helped me reduced nitrite to 0.0 reading
13-08-2006 01:24 by Jo Mack	Thanks. There are about 30 small fish, guppies, platies, tetras etc in it (we swapped from an old tank) we let the tank stand for a week before transferring them. They all seem fine, its just the water looks cloudy. I agree about the carbon bags, and will probably ditch them, they stink and I have never needed anything like that previously with the fluval. I will kep that in for next few weeks. Do you think accu-clear will help or should I leave it alone if the fish are ok? Did you keep the tank or get rid?
13-08-2006 01:36 by Lexter	i sold it only coz at the time i had too many tanks and that was the only tank i could get a quick £100 for i miss it do you have any test kits? i advise you to test for ammonia and nitrite will cost you £15-16 to get them both, but well worth it as for accu clear not sure about that, cloudy water is not the issue, its your ammonia / nitrite readings thats important what flivak filter is it? what size?
13-08-2006 01:38 by Lexter	fluval
13-08-2006 01:48 by Jo Mack	I will get some kits. I have had a community tank for years and have just played it by ear and not really done tests, just good maintenance. Bad, I know but I have not had many probs and the fish I have had have been hardy easy ones. This filter thing has thrown me into a panic because it is not what I am used to! I can't remember what size the fluval filter is, again I have had it for years (hence treating myself to the aqua one) I think fluval 2 rings a bell somewhere. Will test and let you know the readings. Thanks for you help.
13-08-2006 01:55 by Lexter	dont worry, many ecperienced peeps on here dont test waterm its personal choice, i just hope your fluval filter is "mature" meaning its been running in the other tank for a few months, your fish's behaviour is crucial, if they seem happy and normal dont panic, as i said its only wise to test anyway, new tank, 30 fish, definitrly test water, myself and other can guide you through what to do depending on the readings, use this thread i and others will check it over next few dyas, good luck and may the force be with you, stay away from the DARK side
13-08-2006 01:56 by Lexter	GOD how many typos are there from me??? must be these 5 bottle of Hoegaarden and small bottle of vodka!!!!!
13-08-2006 01:57 by Lexter	i dont think Webmaster appreciates my efforts on this site
13-08-2006 07:14 by webmaster	you give some great advice lexter, keep up the good work.
13-08-2006 10:19 by paul stevens	Webbie dont let lexter pull the wool over your eyes he know all sod all hes got a book in front of him reads it from that......
13-08-2006 11:41 by Lexter	THANKS WEBMASTER - I APPRECIATE YOUR FEEDBACK Paul i think its you who quotes from books remember your advice to Kell about her pH, you sounded like a scientist
13-08-2006 12:55 by darren	Found this mate,hope it helps http://www.aquaone.co.uk/homepage_uk.php
13-08-2006 13:11 by Jo Mack	Thanks everyone, I have used one of those Tetra 5 in one test things which seemed the simplest and water is as follows: PH = 6.8 KH = 3 d GH = less than 10 d NO2 = 0 NO3 = 50 Is it the NO3 that I should be concerned with??? ( I am no scientist) I have done a partial water change and treated the water with aquasafe and added some Nutrafin cycle. I still have both filters running, fish still look fine and only one fatality of a very old tetra from old tank so far. I was going to test the water again in a couple of hours. Any advice?????
13-08-2006 13:12 by Jo Mack	Oh I forgot to say to Darren, I had seen the website which is avery slick marketing tool but completely useless as far as info goes. You can download instructions for most tanks but not mine! The info on here has been much better.
13-08-2006 13:22 by Lexter	Hi Jo NO3 is Nitrate, and no you shouldnt be too concerned with that, you have other priorities really, some peeps may say a 50 reading for NO3 is too high, not really in my opinion for the types of fish you have, you would want to look at reducing it to 15-30 ish in the longer run though (this will done through careful feeding and good water changes - 30% weekly in my practice) cleaning gravel with a gravel cleaner syphon will also help Am pleased your NO2 (Nitrite is 0), but what about the ammonia reading???? a 0.0 nitrite reading in a new tank can sometimes indicate an ammonia level and the filters inability to process ammonia into nitrite (hence 0 nitrite readin), but i doubt it in your case, i think now its ok, but an ammonia reading be good to be completely sure. Ammonia is "NH 3" i believe as long as your readings were done according to instruction you dont need to test in a few hours, nothing will change in that short space of time do you have ammonia testing as part of the kit???
13-08-2006 13:24 by Lexter	should have added that stocking levels will influence Nitrate (NO3) readings too how many litres tank hold Jo? and you said approx 30 small fish (i.e about half an inch to an inch???)
13-08-2006 13:28 by Lexter	Jo check this link, not particularly helpful here, but there are others out there..... http://www.aquarist-classifieds.co.uk/forum/viewtopic_1629.php
13-08-2006 13:30 by Lexter	http://www.aquaone.com.au/curvedglass_aqtanks(ar620_ar980).htm is this your tank Jo? 90 litres???
13-08-2006 13:32 by Jo Mack	The tank is only 90 litres. I forgot to say that I used a lot of water from the old tank and I kept the old Fluval sponges in. I realise that there are probably too many fish, but they had multiplied somewhat in the old tank! I don't think the test did cover ammonia unless it is one of the 5 I listed. This is why I have never previously tested, as I am really not sure what I am testing for and what is good or bad! yes, there is about 30 fish half to an inch long, a plec which is about 2.5 inches long and a couple of small clown loaches.
13-08-2006 13:34 by Lexter	Jo accoridng to the site i use for fish stocking recommendations (practical fish keeping) you should be aiming for the following stocking levels in your tank (based on 90 litres) 18" of fish if your tank is newly set-up and not fully mature 36" of fish as your maximum if you wish this with a mature and fully cycled tank in my exeprience you can go above these reccomendations a little bit, but you really have to be 100% with the maintenance and water changes and also you fill fight a losing battle with Nitrate (NO3) readings if you over stock
13-08-2006 13:39 by Lexter	however from my experience and what peeps have fedback to me, lots of common fish if bought up in high nitrate can be remarkly resisileint to levels even exceeding 100.0 this doesnt make it right, but fish can still live a long life, breed etc and look good in high nitrate levels, its just if you buy other fish and put them in high nitrate they can die off pretty quick and gradually get weak, diseased due to weakend immune system Even with very good water changes (30% per week) you will porbably always have 50.0+ nitrate readings in your tank, ocnsidering the amount of fish, and that 2.5" plec will get bigger and they are messy (poo)
13-08-2006 13:40 by Jo Mack	Thanks, you have been great, the old tank must have been ok because guppies and platies multiplied prolifically so perhaps I should calm down and give the new tank time to settle and for the filter to mature. I will have a look on practical fish keeping too. You must wonder how I have managed to maintain a tank for years with so little knowledge, but to be honest, I inherited the tank and fish from someone else about 6 years ago and just kept it clean! I will now read up on the science bit, I promise !
13-08-2006 13:40 by Lexter	if you have water probs your tetras and clown loach will prob be the first to "kark it" or get sick, if they are all looking good, you are prob ok, note "probably"
13-08-2006 13:42 by Lexter	if fish start gasping at surface or die off in next week or so, do get an ammonia reading, if you ammonia is above 0.25 you have a problem, bit i dont wanna panic you, at the end of the day one dead old tetra aint bad!!!
13-08-2006 13:44 by Lexter	i say above 0.25 coz its a new tank, in reality, you always must / should have a 0.0 ammonia reading
13-08-2006 13:44 by Lexter	by the way in the following order is the most dangerous / lethal to fish 1. Ammonia 2. Nitrite 3. Nitrate
13-08-2006 13:49 by Lexter	one other thing in the name of Science Jo your pH of 6.8 is useful in this situation, because the lower the pH the loss toxic ammonia is to fish i have a pH of 8.0 (and it may even be higher) at this level ammonia is highly toxic, below 7.0 is it not so much of a short-term crisis, altho it still indicates a tank / filtration problem
13-08-2006 14:10 by Jo Mack	I will get an amonia test and let you know what the reading is, in the meantime, I have my fingers crossed ! I just wish I had come on this site before putting the fish in the new tank. Hindsight is a wonderful thing.
