Can’t seem to beat this greenish stringy algae . I’ve been doing 10 % changes every week. Running gfo in a reactor and still no help. I’ve scrubbed the rocks tried red flux nothing seems to work. Any ideas I’ll post pictures
one thing I did was start a refugium with cheato in one of the chambers of my Nuvo 20 AIO tank. I use a innovative marine cheatomax light stuck onto the back glass and a intank media basket to hold the cheato and run the light at night for 12 hours. this helped kill off almost all the GHA i had in the tank with in about two weeks. maybe give that a option the cheato starves the GHA out and reduces it.
