Hi all
I have 3 type of algae in my tank and I'd like to know if they are good or bad. And if bad, how to counter them? I am new to start a marine tank so your advice will be very helpful.
Thanks in advance,
Sponge like algae on rocks and snails and on the carpet corals.
Valvet like algae, grow on LR
On glass.
All the algae are soft and they came off easily when rub with just a finger.
