That's the max water temp recommended for effective cooling and maximum efficiency when ran internally. Most aquariums are well under this threshold- 35C is 95 Fahrenheit.
@Reef Breeders probably an odd spot to ask a question but I'm trying to get some information on a couple of the coral box wave makers I have and can't seem to find it anywhere online. Basically I'm trying to chart the approximate gph output for each power setting so I know what I'm pushing through the tank. I have to RN-1 Nanos and a QP-16 (it's not the plus, it's the regular one).
The controller for the QP-16 is also on the fritz so I'm not sure how to replace it or if I even need it when I have the two RN-1 .
