Any recommendations for keeping down water temps?

Short answer, there is no benefit to adding pumps and air stones if your res is at 8mg/L. It will not go any higher. If it is not there, then yes add more air.

Most growers do not have a DO meter, which makes it difficult to tell you if you need more bubbling or not. As a rule of thumb, I have found that a properly driven 2" x 4" cylinder style air stone per plant will get you to 8mg/L.

Moes right, I'm not his wife.
I will add [ not to correct him ] that a properly sized pump goes along with the properly sized airstone.
Alitas have been mentioned many times by those of us who own them as one of the best.

If I keep my shit up the position might just open up.

Based on my growspace if I am injecting o2 I leave the chiller off. If standard RDWC I like 72. @Aqua Man agrees and he’s got a similar climate I think. I think @smoke and @SweetLeafGrow do 70 but correct me if I’m wrong pls

100% right
