![]() If you have a film on top of the water, that indicates to me that the top of the water is still. ( I don't know if I'm right, just trying to rule stuff out to help you )
Try placing one of the powerheads just a few inches below the water suface (not high enough that it sucks air into the powerhead). Aim the powerhead up so it agitates the surface, this will create "waves" which will help with gas exchange as well as add more oxygen to the water, it will also drop the temperature of the water. Higher temperature water will decrease the saturated oxygen level in the water. Adding powerheads generally raises the temperature. Also if your salt level is on the higher end, this also decreases the maximum saturated oxygen level in the water. |

![]() Before I took the powerheads out they were like that. And thats when this all happened, salinity is 0.024. Im scared to put the powerheads back in unless i know theyre clean

![]() The powerheads would have to be dipped in something pretty nasty to cause that much chaos. Diluted to a full tank system, it would have to be something VERY strong to cause something like this. Try looking at other causes, what are your nitrates at? nitrates will strip oxygen from the water faster than anything if they get out of control. You said your skimmer is not hooked up? what are you using for filtration currently? it that leeching nitrates back to the tank?

![]() Nitrates are 0, I just have a fluval 205 running like i have for the past 2 years and I was just gunna install the skimmer and the powerheads, all this happened in one night after i installed the 2 powerheads. I clean the filter alot so it cant the putting nitrates in there.
