Remember, you should be able to flood anything, provided your emergency overflows are in place. If the Herbie valves get really mis-adjusted, then the water just flows down the emergency pipes and makes a lot of noise. You adjust them, and wait for the system to achieve a new steady state.

Here's some fun...I won't even attempt to explain this in detail...but I can manipulate the salinity of my system by adjusting the Herbie valve that runs between my small sump and the main sump. Hint: evap water is monitored by a float valve in the main sump. If you can get your head around that one, then you have achieve Herbie mastery!

I also guess a robot named Herbie!



Or maybe because you can let more flow from your smaller sump into the larger one and therefore not allow the auto top off to kick in even though evaporation is still the same.

But maybe both answers are wrong. Im not entirely sure how your sumps are set up!

Bingo! That valve controls the water level in both sumps, but evap replacement only happens based on the main sump water level. It was totally unplanned, but kind of neat when I figured it out.

You'll have exactly that same relationship between your fuge and the sump.

Yeah and if my fish do not behave I can threaten them with salinity changes!

So I picked up the glass for my overflow today and I may have made a mistake. This is to be a toothless overflow. I wanted it to be as close to the top of the tank as possible but I may have got it cut a bit too close. I got it cut so that it will only be 3/8" under the eurobracing. Will this be too close to the top of the tank? It should only be a very thin layer going over the overflow anyways but it looks close. What do you guys think? Does it make sense how I explained it?

I measured on mine and the water surface to the bottom of the Eurobrace and I have 3/4". I held up an edge at about 3/8" and can't see the distance being a problem other then when the 4 way goes around I might get rippling that high. It would just mean it would get salt creep on the bracing more than I get now. Maybe also the water level might go over if I plunged my arm in until the overflow caught back up.

Yeah thats pretty much what I thought. I think it will be fine...Well it better be. I am also wondering though if the overflow will be big enough to handle the 2" drain. I may have made it too small.

Just realized I have another small issue. My RO unit came with a faucet adapter but I cannot use it in my apartment because it is for threaded faucets (like laundry sink ones) and I just have the kitchen and bathroom sink faucets to use (not threaded just regular faucets). Is there anything I can pick up from somewhere like home depot to use?

Actually the glass is too tall. It just barely leaves 3/8", maybe even a bit less. What a pain...I guess I have to have new glass cut. I don't think they can trim off just a tiny bit for me.

This is all because the eurobracing is a bit lower and thicker than I thought it was. Its 1/2" glass.
