@Donaldj I’m sorry I don’t think I explained. The smell is coming out of top of res. The system is 5 days old only, 5 day old water, nutes and the top of res itself. When I say sealed I’m referring to the top of res being sealed. It’s a 55 gal black drum that has a removable cover that seals it. The temps in the res are actually at 80 degrees now. I do have a water chiller but that’s on the actual hydro system only, water from the top of res does not go thru the chiller, only water from the hydro system itself passes thru the chiller. The temps in the hydro system itself is 68deg. I’m concerned that with the temps in the top of res so high and the smell so bad, that when the top of res feeds the epicenter I’m allowing contaminated water to enter system.
Sorry I didn’t explain it properly the 1st time. Writing was never my strong suit:grinning:
