how would you all go about changing the rez out every 2 or 3 weeks? Do you all use pumps to pump out the water and pump it back in? or just dump back in? what have you found to work the best?
Also my 6-in-1 ph,ppm,temp, meter from some company in china, has recently stopped reading the ph and ppm screens, they are just blank. I was going to be contacting the company, but i thought maybe someone else had the same problem and could tell me whats up
