help they are dying!!!!!!!

4 of my plants are trashed...im thinking low DO the air hoses were outta the water and water was way high... i fixed water and hoses and im gonna flush today....what else should i do??

no one huh??????

I would say you're right, low DO they were drowning. I don't think you need to flush so much as lower the water level to at least an inch or two below the net pot and get some bubbles in there -- as much as you can. I think you should have minimum 2 airstones per plant. I think that's about all you can do...I think they will recover, but I don't really know cause that's never happened to me before.
