I have been running my DIY scrubber for several months and love it but in the last 3 months or so something has changed.
Initially I was pulling off huge mats of turf algae every two weeks but then something changed and what I am pulling off the screen now is a slime/rubbery algae that has taken the place of the turf algae. I clean this sludge off weekly as it grows fast but I have no clue as to why the change.
I noticed the change right after I dosed Vibrant for 7 weeks to get rid of some GHA on the rocks but I stopped using it after it cleared up but the algae sludge continues to grow.
The first two pics are the sludge I am harvesting and the last pic is what I originally started pulling out.
Any ideas?
