ive had my tank running for 10 months now and most recently im gettiing a red bubble algae outbreak mostly on the back and side glass but now spreading to some rocks. every time i do a water change i siphon some out but it seems to come back worse. my current water temp is 77. nitrates are under 5. phosphates are 0. my tank just seems to look dirty and im getting frustrated. im just using a HOB skimmer and a little filter i put some rock and bubble grass in. i have 2 750 gph koralia power heads.
