Gday all, just a quick q, I'm not understanding what is going on in a particular tank (50litre) housing 8 ahlI electric blues. Last week with a water change readings as follows ; ph-7.6, nitrate-0, nitrite-0, ammonia-2.0 (maybe ammonium)...fish look great...This week fish look great normal but water is ****!!! as follows ph-7.2, nitate-20, nitrite-.50, ammonia-4.0 !!!...Nothing has been added, test kits are fine brand new and shaken before use...I have done another water change today but it just looks like these guys should be dead!!! what's going on...I need someone to explain what actually happens so give it ya best shot...thanks a bunch...
