Icp looks pretty good...
System running For 1 year now, the rock in cryptic Chamber is 7 years live

DT is clean and beautiful , clean glass daily/every other.
Frag tank... gets brown/red slimy algae on glass, racks, frag plugs, loc lines, nem box , rock etc..

Frag tank,,,I remove and scrub everything 2x per week, and dose 8ml microbactor , and shut off return for 4 hours for it to set in....(8 weeks now)

What's going on ?,,,, need help

Its hard to see what kind of algae you have.

Is the flow in your frag tank the same as your DT?

I had just cleaned The frag tank,,,, should have taken pics first. 4/5 days will have a new pic..

Good question
DT 5 mp40s and return Lines also offer decent flow

Frag tank,,,,, 10 days ago, I removed 4x mj600's and replaced with 1 tunze osmolater

The return is a bit slower in frag tank as well

My turbo snails in frag are getting hairy algieri on them
