you havent said a single thing to help. "Sounds like you need an ATO" "once you have a mechanism for maintaining your desired water level, report back to us". this is the whole purpose of my thread; to setup an ATO thats going to work with this setup.Nice way to treat people trying to help you.
so, for those in the back.....
im trying to setup an ATO. my pump puts water in the tank faster than the drain can get it to the sump. although slowly, it still causes the ATO to constantly run, all day at about 5 minutes in between. so, obviously, doing this is going to cause salinity to drop, and add more water than what the system is setup for. the only way to combat that is slowing down the return, which then runs me into an issue of overfilling the sump to defeat the setup i have on it.
