Any idea on how much water returns to the sump when the return is shut off? said:Just the water that is in the overflow and waterfall area. I would guess 1gallon.
Its more than a gallon for sure. I also had an issur with my return line creating draining no matter if the waterfall arwa was drained or not I'm sure I had something going on but siphon holes didnt change it either Samsung Galaxy S III said:I have no issue with back siphon. I put a 90 and a T in the waterfall.
When I turn my pump off the water level in the sump only goes up 1 Inch or 2 max. So it for sure is only about a gallon.
You could try one of these: http://www.bulkreefsupply.com/index.php/catalog/product/view/id/1566/ Less than $2 and they've worked well for me. said:Thanks mike
I got one of those too. But I just sold my tang yesterday so don't think I will need to feed nori to often now.
