I'm thinking about doing a black out on my 20 gallon. I have black hair algae EVERYWHERE its ugly and I hate it. I should get a SAE but they require a slightly bigger tank then a 20 gallon (But if anyone tells me its ok then I'm down) I've had enough of this algae and I want it gone. But I just added this small sword plant and its already lost quite a few leaves (and grew some back) But I'm afraid the black out might harm it. Whats your opinion? And if I have a 65 watt light on a 20 gallon do I REALLY need a co2?
I've been putting it off for so long but if it needs to be done I'll do it.
