Thank you very much for the replies. I'm running two HOB
on my 29 gallon one of which came with the ten gallon tank when I got it. Thinking about getting another 30 gallon size HOB
for the 29 gallon and moving the smaller filter back to the 10 gallon. Then if I ever get my 55 gallon set up I'll have two cycled 30 gallons size HOB
for it. The canister filter seems pretty expensive and it looks in videos to be pretty big. I'm actually really like the two HOB
I have now. I already have sponge prefilters on both intake tubes. Thanks again for the suggestions. I appreciate the ideas of other things to consider.
