i have 2 18inch long airstones and 2 6inch disk air stones. along with water pump sending 1/4inch feeder tubes to each net pot. Light could be the issue. there is a very little bit that seeps threw the hydroton rocks very little. how ever the plant have not shown any change besides worse in the last week so im sure there is a problem. i will work on sealing the light up better. any other ideas?
What would cause algy and how can i tell if i got it or not? the inside of the tote doesnt seem to slimy
