Awesome Thread of a DIY algae scrubber!! This is a very good concept and with regular havesting, it will make a superb export machine! Great work guys
Having the large surface area exposed like that also allows for excellent co2 blow off. Nice way to increase the gas exchange
Another thought would be to add a fan blowing at it for cooling purposes. If the fan were on a temp controller, you could easily keep the temp stable! The evaporation would increase so be prepared to top off more often.
I would LOVE to build one of these... just no room right now....
