I have a 55 gal tank that has been running since April. I cylced until beginning of Aug (I went on vaca and didn't want to add the fish yet) and then added a blennie and 4 spot wrasse. Mid Sept I added 3 green chromis, meanwhile all the water testing was perfect. On 9-20 I did a 1/3 water change..nitrates were at 40 and then everything went south!!! First the wrasse died, then the blennie, two days later lost two chromis. Today I have one chromis left. Parameters today are: temp 80, salinety 1.022, PH 8.2, Ammonia is 0, Nitrites is 0 and Nitrate is 20. I am using one powerhead, carbon filter and a biomax filter and bottled ro water from walmart. I have crushed coral, FO with a couple of turbo snails and 5 hermit crabs which are fine. It seems the water change I did killed everyone???? Please help, I don't know what I did wrong and it's making me a bit crazy
:help...
Also, I bought my test kit last year,,,do these go bad???
