Yea, they were the ones suggested. Not sure if I should go for the 1500lph as I think the lighting is quite high and I am desperate to sort this algae out!
Should I do another blackout when the powerhead arrives or, wait and see if the BGA disappears with the increased flow and regular water changes every other day?
I want to avoid it getting a nasty hold in the tank again as it is so foul smelling!
Thanks once again.
