Aquarium Advice Apprentice
Some simple green algae has suddenly started to grow on my rocks in my 40G SW setup. The tank has been cycling now for just under two weeks so I guess this is a good sign that the tank is maturing - however it looks somewhat unsightly on my beautiful rainbow rock. As this rock crumbles easy I can't scrub it off, so what's the best way to reduce/stop algae from growing? I understand Phosphate is a cause of it, so should I buy something for my filter which would reduce this? Any suggestions muchly appreciated!
