The first three times I added one "dose," it didn't do anything, so I started adding 2 doses at a time and had to do so like 8 times just to get it to 6. When will I know if its usable?
If you are going to be near the water most of the day, check it every two hours. If not, check it at least at 12 hours.

Here's what's going to happen: First we see if the pH goes back up to 8.0 or if it stays down. If it stays down, you are home free. If it doesn't, the next step is to put nutrients in the solution and see if that keeps it down. (I start with r/o water that's around 7.5-8.0. After I add my nutes the pH is around 4.5, so I adjust it up.) This is something you might have to screw around with for awhile, but it beats the hell out of hauling water. I have to go get 30 gal. again today and this is getting real old real fast.

PharmaCan Reviewed by PharmaCan on . Suuuuuper High pH!! Finally, my friend has his set up ready to go; all temps within range, E&F working with no leaks, timers working, etc. But he tested the pH with a liquid test kit (its all the hydro shop had in stock besides $120 testers) and it read over 8.0. We waited a couple hours for it to run through a pump cycle once or twice and measured again and it still said 8.0+. Why is the pH so high and what should he do about it? He is ready to germinate the seeds but doesn't want to put them into the system Rating: 5
