Water Physics Question...

yeh thats wat i was wondering about too... i got it all back up n running, MANY THANKS TO SNAILRIDER AMPHIPRION and SUNDEVIL BRIAN!!

im probably going to go out and buy a really strong power head tomorrow, and hopefully it will do the trick... the sump is at the desired level now though! and the float switch is in place incase worse come worse!

thanks again guys! couldnt have dont it without u!
 
Alright guys! The problem is back!
This time I just left the tank running, I came back home today to find out that the sump water level has dropped again, and im back to the same problem... Only this time, the water level didnt drop as much as yesterday...

I checked the overflow box, no air bubbles... I tried to top off the sump a little bit through siphoning some water out of the tank and into the sump... it rose for about a minute and started comming back down...

Solutions?
 
still sounds like an overflow issue, some pics might help. If you do not have a clear/seethrough overflow, my guess is still bubbles or some restriction.


When it worked proper how long did it function correctly, days, weeks, hours etc.
 
it functioned properly probably for a few hours? I went to bed and woke up the next morning to find out it has dropped again...
I sucked out all the air from my overflow siphon today, and even took in some extra salt water just to make sure there was nothing left in there... then i connected the siphon to a powerhead in the tank...

here are 2 pics of teh overflow...

Very interesting indeed. I wasn't expecting that. Is that white pipe clogged or just undersized? The water level in the chamber with the black strainer, should not be that full. Something is restricting that down pipe or you are just pumping way too much water for the down pipe. What gallon per hour (gph) rating is the pump in the sump, LOL?

You may need a larger diameter drain, or a diverter for pump side if your not clogged. OR-if your tank is not tempered, drill it.

So on the piping going down to the sump from the overflow box, are there a bunch of turns, and is there always a "fall" in all sections of the pipe?

I'm running two 1 1/4 inch pipes as overflows, and yours looks like one 1 inch or less. If you are pumping 3-400 gph, that will never keep up. Or if it does only till it gets partially clogged.

So looks like a nice setup and fantastic view. Hope your fish don't get vertigo :)
