my 55 gallon cihclid tank has been doing pretty well but when i cleaned it the last weekend and everything has spiked. By cleaning i mean all the rocks boiled and plants put in the dish washer even gravel boiled. My nitrate nitrite were off the charts! ph was at 7.2. And if cichlids can have a heart attack i think my did. My acei flipped out one night and hit the walls and swam so fast and he stopped in the corner of the tank and was not breathing. A few minutes later he was ok. i have been doing 50% water changes and have been doing that for three days. everything is under control and to make sure i bought some live plants to absorb the nitrites and nitrates. but they will not eat. They havent for the three day period. i even put brine shrimp in to have them eat and usually hey go crazy but the didnt really eat it all that much. I am really getting scared i have had most of these fish for over a year and dont plan on losing them. I will do anything to make sure they dont die. I have a magnum 350 and it doesnt seem to be helping where the exhaust meets the tube there is water spraying out of it. (this is inside the filter) please help should i buy a different filter or what should i do?!!!
