SantaMonica I need your help.
I have a 55 gallon with 20 gallon sump.
My horizontal screen size is 10" X 10"
I clean 1/2 screen a week
I use soft white compact fluorescent 40 watt equivalent, 9 energy used in watts.
Timer for light on 18 hours.
I have 2 clowns
1 Blemmy
1 Yellow tang
Sand sifter star
Mex turbo snail
Lots of yellow sponges
1 white sponge growing in sump.
I added the Blemmy and tang about 2 months ago.
A couple days ago I started getting brown algae all over the sand and several live rocks, I used a credit card and cleaned up sand and tooth brush on the rock. It comes off easy and in the sand its is clumpy.
Anyway my algae scrubber doesn't seem to be producing as much green algae as it should and is green, red and brown in color. See picture. Bulb has been changed recently.
I may have been over feeding with frozen mysis and Formula Two, once a day about 1/8 cube each.
Without totally redesigning my algae filter, do you have a recommendation on getting the green algae growth up? I also use a protein skimmer NA6, and have never done any water changes.
