Floss in the Sump

[CoMMaNdeR]

Do you guys use floss in the sump to trap more detritus ?

I use it 24/7 and my tank is cristal clear. Is this good or bad to leave floss always in the sump?

I just replace it twice a month..

it can start to become a nitrate factory... i would rinsse it out every three days to avoid nitrate build up.....

I agree. Used to use had a problem with nitrates. Remove the floss no more problems with nitrates. Now I use Filter socks for 24 hrs once a week plus charcoal once every two weeks.

I use a filter sock 24 x 7. It catches the crud and helps to prevent bubbles coming from my drain pipe. I swap it for a clean one about every 5 days. I only have 3 small fish in my 58G reef so the bio load is very small.

I think it's fine to use filter floss but replacing it twice a month might be a bit too long apart. As mentioned the waste can break down creating nitrates. You might want to rinse it out in ro/di after the first week


Do you realize the "batting" sold in craft stores can be used as floss. It's a lot cheaper and you're more likely to replace it more often.

fwiw,

I use a filter sock on the overflow pipe if you want to use floss I would put it in the top of the overflow box
