Anyone heard or have experiance with this Algea Mower?
I've see something similar on R2R only it was being used as a SB vacuum. The output has a filter sock type attachment which catches the debris but allows the water to go directly back into the tank.
I didn't watch any of the videos but it looks like a powerhead with a bag on the output and a few different attachements to put on the input. I question how it would remove coralline, aptasia, or algae with a good hold on the rock. Lastly, sucking out detritus from the gravel is only half the point of a water change... what about replenishing elements that have been depleted.
I think it would be a great purchase for say a CLUB. Something members could barrow. Like me So I could remove these freaking shrooms that are taking over my tank!!!
