Do siestas help control algae and do they promote plant growth ? I’ve recently changed my light schedule from 6 hours straight at 65% to a siesta cycle, 3h on, 3h off, 3h on (same intensity). I did this to help fight BBA, growing mainly on Amazon swords, since I heard it can “reset” algae growth and let CO2 replenish during the break, promoting plant growth. It’s been a couple of weeks and I haven’t noticed a difference apart from the longer viewing time after work.

Any suggestions on how to tackle the brown/dark green algae on plant leaves? I’m also dealing with a brown/dark green algae, mostly on my Lobelia cardinalis. I’ve seen people suggest nerite snails in the comments of other peoples posts but I already have trumpet snails. They snuck in on a plant and have multiplied. Nothing crazy but there’s quite a few

Another issue is waste building up on plant leaves which I presume is snail poo. It’s not awful, but I’d like to reduce it if possible.

26gal tank. Dosing liquid CO2 daily. 15ml weekly of flora grow pro. Occasionally root tanks for Amazon swords (~2 per month)
