Thanks for the encouragement! This place is pretty active!
So is there any advantage to having one of those cubes with the separate filter chamber in the back instead of a hang on the back filter system?
I will look into mechanical versus arduino ATO. I really want to play with the arduino, so that is a factor here
Speaking of ATO - is it imperative that I use RO water? My old buddy years ago used to top off with straight tap water, chlorine and all. I think the accumulation of minerals over time is probably not the best.
Also, why do a lot of tanks have no glass cover on top? Can't that make more water evaporate or is there some benefit I am unaware of?
Thanks for the help everyone, I've been wanting to buy a reef tank for 10 years... now is the time.
