You need to find the cause of it first. Easy to get rid of but will come right back if the same conditions exist. Is not normally found in tanks which have good plant growth
in them. Though frequent in start up tanks, it usually leaves on it's own if the tank is made healthy. So...
What size tank/exactly what light and for how long/what if any ferts, CO2 etc.
The more specific you are about these, the easier it is to see anything that may be the cause of the tank not being healthy.
Oh yea I took the wood out a week ago, I just wanted to know how I can get the algae off. I tried scrubbing it off before, but unfortunately to no avail because thats shy the algae came back. I just want to know if there was a way to get rid of it. So would dipping it in a bleach solution work?
