ive got a 24 gal aquapod. I replaced the pump and put two maxijet 900s. one has a hydora agitator the other half inch locline with 125 spouts. i took out the filter crap, and only have a bag of chemipure. i also have stock lighting and you will need to replace the fans as i do for only around 6 bucks a piece you can get some killer ones to keep the temp great. i live in colorado so my concern is only the cold but i just crank up the heat a touch and everything is great. I have great flow reduced nitrates to zero and all other parameters are perfect. water is crystal. diatoms are all gone after a couple of months. no disease and i have sps lps and 4 fish with crabs snails anemone etc. what else are you hoping to do?
