1.5 days after removing Rowa and i can see hair algae disappearing !
Wow.
So i decided to put ZEO back on 3hr on/off timer just in case if change is to quick.
Side note; if ZEO rocks are so quick to remove Po4 it makes Rowa obsolete is it not?
Because ; ZEO rocks are chipper, lasts longer and you need less of it to remove phosphates ! The only draw back is a need for shaking though, and not too comfortable without special reactor.
What i am doing is that i have Zeo rocks in the regular plastic net from oranges and i have it in separate small container in the sump (small power head is for flow from sump in to separate small container that overflows back to the sump) with plastic rod attached to the plastic net/bag so this makes it very easy to shake.
