Hi all, been battling with algae since a few weeks after setup, it did clear up and plants started looking alot healthier then in last couple of weeks its come back with vengeance and covering all plants substrate ect. I have had a bottle of flora grow columbo c02 alternative for a few weeks now but have been sceptical about using it as certain things i have read. Was wondering what's people thoughts are on this and is it likely to help? also do you just pump it straight into tank? and is there a certain time of day that's best to add it ect?. TIA
