Hi,
I just setup a new tank.
Was running for month plus.
Everything was working fine.
Yesterday, I added Rowa.
So suck out 1 pail of brown water.
To replace the lost, I did a pail of RO water n mixed with salt n refill into sump.
Till today, my skimmer still overflowing.
It started just after what u did.
Please help.
I tried to raise the skimmer, adjust the knob...all cannot stop the overflow.
