New to reefing, I bought a used 75 g tank due to price constraints of new tank and hope to rehab back to life. Picture did not do the algae problem justice. Glass was covered and every piece of rock was covered in green hair algae. Got it home cleaned everything including pumps, sump, skimmer, power heads and any thing the we could stick a brush in. Once clean we sifted water to remove large clumps of algae and other debris, added new sand.
Have had the tank for a little over two weeks now and the phosphate are below 0.01 but the nitrate are at 160 ppm and don’t seem to be coming down. I have been doing medium water changes, about 12 gallon 3 times a week. Setup on the tank is an HOB skimmer ( I know, isn’t great) HOB overflow to a 10 gallon sump with 1 sock, a sock of activated carbon in the middle chamber of the sump and a piece of live rock as well. Lights are set to acclimation at 50%.
live stock in the tank is one clown, a blue-green chromis, dwarf hawk fish, and a dwarf Pygmy angle. Also a couple snail and 2 urchins. Coral include 1 mushroom and a
Hair algae is still trying to grow and some signs of what looks like cyano are staring to appear.
What is there to do about the high nitrates and potential cyano?
