i Have a problem i am getting a alge bloom. I have a 18 gallon reef tank with a aqua clear 300 outside filter with reef carbon in it, and i have a seaclone protein skimmer that is for aquarium up to 100 gallons. and ever thing was doing good for a long time then all of a sudden i have alge.but i have tested for nitrates and they are at zero. and all other test are where they should be. but i dont have a phosphate test. could this be phosphate. i use RO water for water changes and to top off the aquarium. the alge is brite green on the side and brown on the bottom.
