henward Posted December 9, 2008 Report Share Posted December 9, 2008 i have a new sump set up. i have used old established filter media, but they were just immersed in a make shift tank previously, and had an fx5 running in it as well noww i removed the fx5, only the sump is there, turn over isnt hte problem, the bo media is obviusly not used to doing the entire filtration. AMMONIA IS 0, completely nil. but nitrite is between the first colour and 0. very slightly. i put a lil salt to detoxify it and prime also. is there anything i can do wiht out costing money to quickly establish the bio media to quickly get it to digest nitrite too? i know tht bacteria that eat up nitrite is the secondary bacteria.... first comes the amonia eating ones first right? never had nitrite problems before, usually my canisters take care of it all, but this is also the first time i have had to use a sump.

David R Posted December 9, 2008 Report Share Posted December 9, 2008 Cut back on the food until the filter is running properly. Less waste will mean less nitrites. Quote Link to comment Share on other sites More sharing options...
