or you light it 24/7.

if your leaving your tank alone for weeks at a time i suspect you have bigger issues than pruning your macros every once and awhile. just an fyi, that’s all i use for my filtration is a big fuge with a micron bag. with all the macro's i have i prune them once every 2 weeks or so. i have never once in 4 years had an issue with macro blocking my return pump because there are baffles between the fuge and the return. i also keep them lit 24/7 and as muck has said cheato cant go sexual and basically grows in a tight ball.

Okay, but I still see a risk of the return pump becoming clogged, which was the original reason for not going fuge.

And sorry for hijacking this thread. It just kinda evolved that way.

Cheers,

it might be hard to see but behind the upright are a few baffles, there is no way any macro is going to get thru that and then past gutter screen to block the return pump.

1. bigger issues ? What do you mean?

2. So do you have filter material stuffed between the baffles?

Cheers,

Yes it is hard to see. I take it the flow is from left to right? So the upright you mention is the vertical glass the water is going over on the right? I can't make out the gutter screen. Is it visible?

Cheers,
