Question

How do I put filter floss into the bottle filter?

Community Answer

Roll the filter floss to the size/thinness you need, then use a solvent and liquid to make the floss slippery enough to get inside the bottle filter.

Question

I installed an ultraviolet chamber in a 40 gallon tank with amazing results! Soon turned into fuzzy overgrowth of rusty colored mess throughout the tank -- are they related? Is it bacteria or algae? Do I need a test?

It's probably bacteria, test if you are concerned, but it's probably nothing. Monitor it for about a week and if any problems come up have a test.

Question

What bio-media is better: bio-sponges or ceramic rings? Which is more better at filtering: a waterfall or submersible powerfilter?

Community Answer

Ceramic rings work better, and the waterfall would work just as well as any.

Question

Can I use a normal kitchen sponge for the filter?

Community Answer

That would probably be too thick, and water may not be able to get through.

Question

\What if stuff gets stuck in the bottle filter, like small fish?

Community Answer

Turn off the filter and pull out the fish. Put a mesh screen over the intake and turn it back on.
