I don't think I mentioned anything about Chlorine. He is asking for a way to cool the resevoir water down without a chiller. I tried to find the thread that I read on another site but several people tried the fan thingy on the res water and all reported reduction in water tempature by 10 degrees or better. I tried it on my 50 gal resevoir and it did indeed reduce the tempature of the water. I will try to find the thread . It even explains techniquely how the hot air outside the res doesn't keep the fan from cooling the water . It is interesting stuff for those who may not be able to afford a chiller .
BILL THICK Reviewed by BILL THICK on . Reservoir temp 85: anyone tried this? Hey everyone. I want to try hydro, using a Rubbermaid 35-gallon reservoir (flat bottom). Itâ??s the hottest part of summer (100 degree plus everyday). I have a some bottles of liquids sitting on the floor of the room (nutes and pH down). To find roughly what temperature my reservoir nutes would be at, I measured the temperature of the bottle of pH Down, at the hottest part of the day. It was 86 degrees -- at least cooler than it was outside. And since the nutes flow in and out of a Rating: 5
