You pump has been on the whole time? It should not be possible for the FC to rise ... so one of those 2 tests was off or it was not fully mixed after an hour (which is surprising).
Well that explains it. Usually we recommend you leave it off so you get a feel for the FC consumption. IF the CC stay low, leave the pump on and turn the SWG off and try the OCLT.Themacdadt said:Swg is on 10 percent
