Posted	Ocean rocks and Coral sand
05-06-2007 09:37 by Woz	Could someone tell me how much the water would be buffered if i was to add around 50kilo of ocean rock and a fair bit of coral sand to the floor of my tank, it currently has around 9 or 10 bristlenoses in it and ive added 3 pieces of ocean rock already and there all still fine.....just want to know how much of a difference it will make...cheers
05-06-2007 20:24 by JOHANSWAN	only problem is it will push your ph up to about 8 and your bristlenoses should idealy be in a ph off 6.5 so best bet is add coral sand and rock over a week with a fair bit off peat in your filter to try keep your ph down
05-06-2007 20:28 by Jim Son	johan i think you find "buffered" is technically to do with "hardness" and more specifically kH all you'll get here Woz is vague predications and as for Bristlenose they wont give a **** is the pH is 8.0 so no probs there
05-06-2007 20:30 by Jim Son	with respect to Mr Swan as for Bristlenose "ideally" being in a pH of 6.5 thats about the same as saying Human Beings "ideally" should have 3-healthy balanced meals per day, no alcohol, no refined sugars and 43 portions of fruit & veg per day No disrespect Johan, i am sure "technically" you are not "wrong" as such
05-06-2007 21:44 by JOHANSWAN	if you put discus for excample in ph 8 they will also live but will be being stuck in a room full off smoke my idea off fishkeeping is to create the enviroment as close as possible to the enviroment they came from with the water the same parameters as where they originate from so i reckon there is fishkeeping and fishkeeping
05-06-2007 22:50 by robert.pope	Woz why add it when you have the b-noses in there? perhaps re consider the fish compatability or move the b-noses to another tank
05-06-2007 23:10 by Jim Son	the water effect of ocean rock is not the issue here, the bristlenose will prefer a planted tank with bog wood
05-06-2007 23:33 by big cats	sorry woz i am a little confused,why do you want to alter the water chemistry of your tank? crushed shell in the presence of acid water will dissolve causing the general hardness and carbonate hardness to be raised this prevents other reactions and allows the ph to rise, when the water becomes neutral the reaction slows and often stops thus BUFFERING TO NEUTRAL coral sand and ocean rock will continue to react into higher ph levels 8 or 8.5 so the answer is dependant on what you are trying to achieve. 50k of ocean rock will give malawi cichlid conditions in almost any tank,let me know what you want to do and i will try to help
05-06-2007 23:52 by Jim Son	are you sure big cats? it really depends on tap water GH and especially KH as to what long term effect the ocean rock will have
05-06-2007 23:55 by Jim Son	if the kH aint that high you could put LOADS of ocean rock in your tank and the pH will NOT rise that much, if at all
06-06-2007 09:04 by Woz	right sorry people, i didnt explain myself enough....the tank is going to be a malawi tank, and i plan on putting the bristlenoses in with the malawis, not ideal for them i know, but ive heard of people having them in the malawi setups with no problems....im not going to bung it all in at once, they are getting slower introduced, as it is, i believe the water is naturally quite hard, and the majority of my fish have been living in the water for atleast a couple of years with no problems...thanks for the help so far guys
06-06-2007 10:17 by big cats	everything depends on the composition porosity and source of the ocean rock,it is by its nature very high in minerals and never subjected to acid,when placed in an acidic environment most rock and stone will dissolve even marble.the starting levels of kh and gh are of little relevance it is the ph levels or acidity that effects the corrosion of shell rock or coral(gravel or sand) the higher the surface area the more extreme the result so you could put ocean rock in a tank and have such a slow result that regular water changes nulify its usefulness.woz you may need to do very little for your malawi tank to be successful check your water first its probably hard and alkaline anyway,but a malawi tank will never be the right place for a bristlenose
06-06-2007 10:47 by Woz	thanks bigcat...ill be checking the water today when i can be arsed to get off my backside and get a test kit, i already have one malawi setup which has been running for about 5months, so far no problems with that...touch wood
06-06-2007 12:32 by keith t	What a load of tosh, the advice given on this forum makes me laugh. Just a load of contradicting speculating old cr8p, Best advice mate is to use a dedicated malawi forum.
06-06-2007 12:36 by Woz	what are you saying is *** keith...anything in particular
06-06-2007 12:41 by paul stevens	Fight fight fight.... Watch him woz hes the rock and the rocks a kicking...
06-06-2007 13:33 by Woz	haha,,,yet another usefull comment from paul
06-06-2007 13:38 by paul stevens	What ever do you mean woz...
06-06-2007 14:03 by PaddyD	um - I would actually recomend you do not use coral sand with malawis. 1) Usually not needed 2) Washes out the colours of the fish as the light reflects off the sand. 3) There is a risk of mouth infections and skin abbreasons as the grains are rough. I have kept tanks both ways - coral sand can be ok, but be aware there are negatives.
06-06-2007 14:51 by Woz	o, wasnt aware of that paddy
06-06-2007 23:35 by big cats	paddyD wonderful! this is why people use forums like this ,because you can find useful information and learn things you dont already know unfortunately someone is always prepared to be critical without substantiation, not helpful really?
07-06-2007 00:04 by Jim Son	yeh but enough about Paul
