Well I always rinse with warm water and rub the tub's inside with my hands (wow that sounds weird) to get all the salt build up out. Then I usually rinse with cold water to make the res a little colder.
I completely covered my lids with some reflectix tape so I'm pretty sure no light is going in. I used 1 of these containers for 2 plants. I'm pretty sure that the water temperature was a little higher than it is this grow.
I remember that the netpot holes I made were actually a little too big, so I duck taped the netpots to the lid from the inside, where the water splashes up. Could that possibly have anything to do with it?
And what do you suggest I do for now? What could those bacteria exactly be doing right now?
Also one really weird thing is.. when I finished the first reservoir, I left the water running in the tub - with the little drain plug in the tub - so the tub filled up. When I came back with the other reservoir.. I found some kind of green grasshoper in there.. I'm not sure where I first saw it though.. maybe it was in the 2nd container and as I brought it in, it jumped into the tub? Maybe it came out of the tub some how? Maybe it was just there... but can that shit grow in a reservoir possibly? lol sounds so dumb, but maybe it might have something to do with it. Anyways... let me know what you guys think
