Hello everyone, first timer here. I recently got a new 29 gallon tank and set it up with a light layer of coarse gravel, some fake plants, a 150 watt heater, and a inexpensive hang on cartrige type fiter, I filled it up with my well water and 30ml. of Proaquatics water conditioner and got everythng running. By the next weekend I could no longer resist the temptation to get a Oscar (3-1/2 inches) and a Pleco. (about 3 inches) The fish seemed happy and the water stayed nice for about two weeks and then it happened. the water looked cloudy and the Oscar was totally bummed out (hidding in the back corner and never begging for food) Even after massive water changes I could not get the water looking good. Still learning about biological nitrification I went and got a new filter, a Fluval 204 and set it up with all new media. First basket carbon, middle basket polyester floss and third basket biomax. Now the water looks great and I understand it's going to be a while before biological part of the system starts working but what do I do in the mean time. last night the ammonia was 1.5mg/l and the nitrite was 0.3 mg/l. I cut down to three or four medium chiclid pellets a day and added 25ml of A.P. Ammolock, within one hour the Oscar was happy again, but in the morning he was back to hiding in the corner. My question now is do I add more Ammolock, change water, or just sit tight and wait?
