I have a 55 gal
display tank with a sump and refugium with macro algae.
Recently I have experienced an algae bloom in the main tank, hair algae and cyanobacteria.
I've been doing weekly 10% water changes to help. I keep track of my parameters and they all seem good to me but I still have the algae? Took a sample to my lfs
and they confirmed that the water condition is good.
An employee at my lfs
(who has a marine tank herself) suggested that I really should have a better cleaning crew( I only have one snail and some hermits, one sea slug) to handle the algae. She thinks that more snails would really help control the algae...
