yeah i was using drip clean, i did some reading and it seems if i am using drip clean i should be using it from start to finish, and i started this on day 15 or 17 so apparently it can cause problems, and yeah was not much sitting in the bottom but with the way the airpots are designed it does soak it back up. gonna just finish up building the damn drain table on the weekend and hand water until then. will get some pond liner and drill a hole in the middle of the table let it just run into a collection valve.
still pretty crazy amount of buildup after just a few days, i was even cleaning out the trays every 2 days. i want to get it working though cause will be worth it in the end when they are dialed in better.
