Is there more flow in DT than frag tank?

 

[DC Reefer]

I just added a small frag tank to my 155 gal display and had algae in frag and a lot less in DT. Just added some snails a few days ago and they have been busy.

Is there more flow in DT than frag tank?

I recently, removed 4 small maxijets and replaced with 1 tunze...
So as of 1 week ago no.

The dt has stronger returns, faster drain and 5 mp40"s

Scrape out sim of the reddish brown gunk and put it under a microscope and see what it looks like. Seasame seeds doing flips the you have Ostreopsis Dinoflagellates, longer sticks diatom. Filament cyano. Treat from there
