Your suggestions worked great GPS. The system is up and running again and the PH is stable now.
I have it going and it is working fine. The water is doing what it should be doing lol..
There is a good bit of h2o2 in the system. I didnt measure just started squirting it in there till I decided I was bored with it lol.
The plants seem happy to be in the system now. I can tell a good difference in the plants in the few hours they have spent in it. There is probably about a 1/10th strength solution in there right now.
I will take some pics of the plants when I get more than just 2 leaves lol. I also have some tomato
seeds germinating in the system as a test of laziness. One has started showing rooting atleast, so I think it is working fairly well.
