Ohk so if i do daily water changes of 50% wich i can do easy ill be on the right track? Cos 50% a day is easy but i dont wanna do 100% cos its like setting up a 3foot tank everyday which is crazy in my opinion and nothing to enjoy cos u working like a slave, im happy with doing 50% a day and lets c how they turn out and no cross contamenation took place just moved the discus from small tank to new tank and moved pump and gravel over from the old discus tank? Like i said i got nitrites down to 0 so lets check, this is the 1 0 1 of keeping discus fish in the blind with no water test kits ens ens ens like in the stone ages haha f@ck i hate countries that dont have everything fish need cos of price involved of the import stuff... ill just fly over to the states and marry a american girl and problem solved haha sorry not many would like my british sence of humour haha very dry and poor taste ;D
