    Hi all,

    In my absence my fish tank has grown a truly impressive amount of algae that keeps coming back. I’ve limited the hours with my light on to 6 already, and don’t want to stunt my plants by limiting it further. I’ve started using daily flourish excel, as that worked for me in the past to control algae, but this one is back with a vengeance. Any other tips for managing this outbreak??

    What type of algae is it? If it BBA algae increase the dosing of excel for a week then go back to normal dosin. If GSA then dose potassium and phosphate and increase amount of time the light is on. Those are the fixes I know.

    If its green algae, then lowering the phosphates in the tank might help.

    When I had really bad green water, I shortened the time the lights were on and added a filter media bag of fluval phosphate in my hob filter and that got it cleared up in a week.

    Also, can you manually clean any of the algae out so there's less in competition with your plants?

    How big is it? Snails, shrimp, often siphoning, minimal light, and plecos (if your tank allows it) are all ways to help
