to fix this either you need a bigger overflow
or
have a ball valve put in place after the sump to redirect water back to the sump

oh mann...does having a valve decrease the amount of water being filtered or slows down the process? does that mean i would need an additional filtration system?

it looks like i have the biggest pipe available for the overflow. how else can i maximize that area?
 
Bubba..no offense ment..but just bit more research on your part would put you in a much better position with your sump project..that said..you only have a few choices. Get more water into your sump..fittings, tubing size. Control the output of your pump..ball valve,gate valve(my choice for better control),or recirculate the pumps output, most goes back to the tank and the excess gets run back thru your sump.
 
Show a pic of how the water is leaving the tank to go to the filter. Is it just the tube hanging in the tank or is there an overflow box or??
 
From the pics I'm gonna assume that the sump fills from that bulkhead drilled in the bottom of the tank. If this is true then you should install the before mentioned ball valve to "trim" back the amount of return water from the sump until it is the same as the maximum amount of water the intake can drain into the sump. If your pump runs dry it will burn up. If your pump is running too slow your sump can overflow IF it is not capable of holding the water that will drain from the tank. With that said the water will stop draining when the pick up reaches the surface level and then it can only drain as much as what you are pumping back into the tank.

Hope that wasnt too much of a run on sentence.
 
Make sure the water isn't rising in the tank while it's falling in the sump. If it's decreasing in the sump but not going above the overflow you either have a leak or a lot of evaporation.
 
alleykat, you're right, i have an overflow box where the water from the tank falls by gravity...

rallyman, the water in the tank seem to stay at the same level (where it meets the drain for the overflow box) and is consistent....the same goes for the sump...

the chamber for the pump always has water so it doesn't get dry, dry...But the pump doesn't get totally submerged.

here are some more pics.

i shortened the tube that connects the overflow drain to the sump hoping it will increase the water flow to the sump. but it didn't really helop hehehe.

It wont hurt to add some more water, even if it does cover some of the bio balls.
 
does it make a difference where i add the water? i added some more in the pump chamber and the pump just pumped it right into the tank heheh. bringin me back to the current level.
 
it wont matter where you add water, it'll all eventually go into the sump. I usually add it to the tank. You should be able to watch the water level go up in the sump as you add water to the tank.
