I just got done setting up the tank and releasing the fish. I couldn't get the HOB filters to turn on and work properly and I noticed they weren't working well where I got them. I found there where cracks in the filter line where water comes up from. So, I put plumbers tape to close the gaps and got the filters working. The tank came with two 30 gallon HOB marineland filters; these filters have a bio-wheel, filter wool, and an exta slot for another filter media. The setup also came with an 2 undergravel powerheads? I got one to work but the other is not working. As far as fish go, the setup came with 4 silver dollars, 2 angel fish, 3 snake looking fish the seem to be algae eaters, two catfish, and a couple other fish I have yet to identify. I will try to post a picture of it if I can figure it out. I will probably have a lot of questions for everyone. If anyone can give any words of wisdom I would appreciate it.
