Sounds nice, especially the auto-shutoff feature.
I rigged my DIY skimmer up with a collection bottle and an overflow line that runs back into the sump. It has worked flawlessly so far. Since the skimmer is about 6' tall, the pressure makes sure it will flow through the collection set-up and at that height it is right at the head pressure limit of the pump feeding it, so it can't overflow the cup.
I also put a carbon thing on the top.
One thing I have wondered about and one reason the auto shut-off on the unit you are getting is great. In the event of a skimmer gone wild, you also run the risk of having the ATO kick in and lower the salinity.
With my setup the most water that could ever be removed is one quart, but in a setup where the skimmer could dump gallons out of the system, that could be disastrous.
you go on vacation and come back not only to a flooded floor, but a burned out ATO pump and possibly dead brackish water tank as well.
worst case extreme scenario of course, but I do wonder how you guys manage that if you worry about it at all.
any thoughts anyone?
