catshanon Posted February 12, 2008 Report Share Posted February 12, 2008 Hi Everyone, I got my hands on a used 30G which came with a Magnum HOT 250 canister. However, it doesn't come with the biowheel. I popped by BigAl's today, but they don't keep the bio wheels for Magnum anymore. I was suggested at BigAl's to use the HOT for mechanical and chemical and use a separate filter for the bio part. I see in this forum that Werner had suggested that biological filtration is not required if the tank is well planted. I am planning to plant it very heavily without CO2 injection. Should I go with just the HOT canister and a well planted tank or should I put in an extra filter? I plan to put in 10 cardinals, 10 rasboras and maybe a betta in that. Will this result in overstocking? Thanks in advance for everyone's opinions. Raj. Quote Link to comment Share on other sites More sharing options...
Sam Chicklets Posted February 12, 2008 Report Share Posted February 12, 2008 The magnum is filteration enough for a 30 gallon tank. Also those little fish won't put much of a load on your tank, you couild easily double your cardinals. Quote Link to comment Share on other sites More sharing options...
