What do y'all recommend for ATO? I'm running a 65 gallon with another 20 in the sump ( nominal ) and get a decent amount of evaporation. Though I've been cycling it with the hood off, I assume when its on and the MH's are running it will be around the same amount. I dont want to break the bank on it but I do realize its an important piece of equipment, especially when I came back from the weekend and saw my pump almost sucking air.
