you know what? it snapped back in just a few hrs. i have over watered in the past. trying to quit. even joined a 12 step program. lol Its a drip feed, i have two air stones. dont seem to be many bubbles. cheap ones, picked them up at wally world. going to try pet shop. would like to see some splashing down there. as far as watering, twice a day about 5-10min 1gph. to much? i will update my journal soon lots of changes. space wise. new seed gremming. and maybe new t5 in the old spot.
