Posted	planted discus tank HELP.
02-09-2006 11:25 by FISHY	SORRY TO KEEP POSTING LINKS BUT I RELLY NEED TO NO A.S.A.P. will having a: kh of 70mg/l or 3.9 degree's gh of 80mg/l or 4.4 degree's will this cause my ph to crash? are these redings ok for plants? i have 60%ro/40%tap mix as my nitrate redings are thro the roof if i just use tap water and my tap water is very hard. so by doing a 60/40 mix i get the readings as above. the aim is a discus/planted tank with a few rams, tetras, clown loaches ect ect. thanx
02-09-2006 11:26 by FISHY	sorry for my spelling. not to good at english
02-09-2006 11:28 by FISHY	ino discus are soft water fish and ino discus whould be ok at even lower gh/kh but i want a planted tank with other fish in there to. witch is why i could do with knowing the best redings for a discus/planted tank. i do not want to bread the discus.
02-09-2006 11:46 by dean220967	i have kepted and even spawned discus in hard water...they will be happy as long as nitrates etc are under control
02-09-2006 11:48 by dean220967	if you re just starting with discus then can i suggest getting some muts from somewhere and leave the more delicate strains until you have more confidence
02-09-2006 12:18 by FISHY	i have had discus before but never in a planted tank. they are easy to keep in ro water i just want a planted discus tank
02-09-2006 12:31 by dean220967	i think your worrying a bit to much about it, as long as the discus are happy and the plants are growing then everything is rosy what size tank are you going to use? what substrate, filters etc
02-09-2006 12:40 by FISHY	6foot, 2 juwel jumbo filters. very fine layer of gravel and maybe mix some onyx sand in it
02-09-2006 12:44 by FISHY	what whould you use tho??? i have perfect ro water to hand. but i carnt use pure ro as the ph will not be stable. so how whould you go about doing it?
02-09-2006 12:44 by FISHY	what sort of harness gh/kh do you need to keep the ph stable?
02-09-2006 12:50 by FISHY	i whould rather use 100% ro and then add something to raise the hardness. and something to stable the ph. that way nitrates will be 0mg/l. any ideas??
02-09-2006 13:30 by robert.pope	Fishy have you looked at other web pages? i have been reading about the plants on practical fishkeeping website! have a look its about ro water hardness etc http://www.practicalfishkeeping.co.uk/pfk/pages/show_article.php?article_id=479
02-09-2006 14:20 by FISHY	TAR MR POPE. so acording to that my water is perfect. i have: (just tested 5mins ago) pure ro water: kh=60mg/l gh=80mg/l ph=6.98/7.00 tap water: kh=130mg/l gh=180mg/l ph=7.47/7.48 can i just use pure 100% ro water with the results shown above? what do i need to add to this? just a ph stablizer? i have rams, clown loaches and cardinal tetras in the tank is this water ok for them too? im pulling my hair out trying to get my head around this as so many differnt people tell you so differnt things
02-09-2006 14:33 by dean220967	i have 3 pods before my ro unit so the waste water is usuable to, therefore i mix some of this with the ro to stablise everything, this way i dont waste a lot of water. the first pod is a i micron filter its amazing how much silt is in tap water, the second is a nitrate filter then the last is a metals filter
02-09-2006 14:37 by FISHY	i have three filters too. what readings do i need for it to be stable
02-09-2006 14:39 by FISHY	Canister 1- 1 micron string wound filter Canister 2- granulated carbon post filter Canister 3 - Inline carbon prefilter
02-09-2006 16:48 by Ray	your tap water is fine for all the fish you want to keep,the discus would need a lower ph for breeding but will live with your reading no probs
02-09-2006 16:58 by FISHY	so you recon to use tap water not ro water? what are the ideal gh/kh ray for the fish plants i want to keep? about a 100? also what whould you use to lower the ph? make ect ect tar
02-09-2006 17:26 by wymcot	Fishy, why do you keep asking the same question on different threads, you got the answer last night that your water was OK for Discus. http://www.aquarist-classifieds.co.uk/forum/viewtopic_5376.php If you dont like the advise your getting from all the well intentioned folk who have advised you, why not start researching the web like the rest of us do when we are not sure
02-09-2006 17:38 by Ray	I would bypass the membrane so the tap water goes through the prefilters to remove particles, heavy metals and chlorine,basically a HMA.If you ask ten discus keepers for the right parameters you will get ten different answers,but your water is fine,I keep my fish at similar levels and Amazon swords and vallis are doing well.The only thing you might want to do is to remove nitrates with a resin,I would not worry about the ph, peat will lower it but will also affect the KH,sorry to be vague but I measure TDS in micro siemens so have to think about mg/l or degrees in KH and GH.
02-09-2006 17:42 by Ray	Just had a thought,why not take out the ro membrane and put nitrate removing resin in the membrane housing,should give you perfect water.
02-09-2006 21:14 by FISHY	THANX RAY. and wymcot what are you on about last night no1 new the answer to it i just got advice soo??
02-09-2006 21:15 by FISHY	all that hapened on that thread is like always people start going on about something else!!
02-09-2006 21:33 by wymcot	Fishy- copied from last night thread "Fishy the parameters you posted yesterday are OK for Discus and you do not need to make any alterations KH 70mg/l GH 80mg/l PH 6.8 As KH & PH are directly linked to one another your low PH would indicate a lowish KH. GH however is a different thing but yours isnt that bad and you can help to soften the water by adding some peat to your filter I agree with your second comment though about changing the subject Anyway, hope your a lot clearer after todays advise
02-09-2006 21:40 by FISHY	yer tar mate im getting there
