Hey Aquanut,
Thanx for the info! I was adding 2 airstones as You were posting I would guess. I lowered the water--it went down about 3/4", so now I am going to watch the plants and go from there. If worst comes to worst--I have another tub identical to this one, so I will just do the drainage differently and add a timer.
Thanx for the Heads-ups everybody!
