Tadpoles in the grey tank??
OK, so I've been stranded for several weeks waiting on a warranty repair for a blown head gasket for the truck to tow my 5th wheel. I noticed a few days back, during a period of rain, that I seemed to have a frog somewhere in the rig. Didn't give it much thought until I went to dump my holding tanks this morning. As usual, I dump the black tank first, back flush and close it off. Then move on to the grey tank and back flush it.
I should mention at this point that I am full timing and have been leaving the grey tank open and just letting it flow through. I suspect that it might hold a bit of water as the valve never seems to open quite as far as the black tank valve does. That said, I always back flush it when I empty the black tank.
Anyway, as I back flush the grey tank, I notice in the last bit of water leaving (I have the see through attachment) that there appears to be tadpoles in the water. I back flush again and see that there are indeed tadpoles.
So... here's my question.....
What is safe to add to my grey tank that will kill these unwanted parasites?
I also wondered if this were a common problem for anyone else that left their grey tanks open, to flow through?
