Algae is getting annoying...

[johnm92172]

Have a 115 gallon fish only tank with a wet dry sump. All rock in tank is resin. Have a 3 inch sandbed, and have a yellow Tang, hippo, flame angel, maroon clown, diamond goby, fairy Wrasse, bicolor angel, and cross hatch butterfly. Phosphate is 0, and all other parameters are exactly where they should be except for nitrate which is about 20ppm.i have a coating of green very short hair algae on the "rocks" that dull the colors and never seem to recede. I run biopellets in a reactor which never lowered the nitrates, run a UV sterilizer, a reef octopus skimmer in the sump, and 2 kessil 360X at at peak 40% intensity. I also have an algae scrubber that's been in the sump for 2 months with 10hrs of light that I'm always scrubbing slime off of. I feed 3 frozen cubes of food which I defrost and dump the liquid from with a few drops of vitamins and 2 drops of garlic. My question is, is it possible to have these rocks free of algae to let the colors shine through?

Yes run your scrubber longer maybe 20 hour a day

I think that'll be too much. I had it for 16 hrs a day and was getting a lot of slime.

I have had a reef tank for 11 years, I have always had algae problems, hair, bubble, dino's cano,you name it. I decided to get rid of the sand and go bare bottom. Ever since I have not had any algae except for a light film on the glass, and it's been 4 months. Granted there are some critters that need sand.

when I covered the red lights on the lighting the algae went away.

Resin rock are known to have algae growing on it seen from most of my fellow reefer.

You may use Vibrant to kill those algae or hardworking tang. Just wondering how strong is the flow in your tank?

I have 1 Vortech MP40 that varies in flow. No long haired algae; just a fuzzy coating on the rocks.

Post pics of your scrubber, I might be able to help you dial it in.
