Hoping someone here can give me some advice on this problem I cant seem to solve. Its driving me CRAZY!
I bought a used 80 gal
bowfront tank from my LFS
that they had up on consignment for a pretty good deal about 2 months ago. I'm not 100% sure of what brand all the equipment is but I have a skimmer, a wet/dry, PC
lights and a 5 gallon sump (might be a little more than 5 gallons, not sure). In my tank there are two long vertical tubes, 1 is a return and one is a send from the sump under the tank (someone just told me this is an 'old' system that they dont make anymore???)
At least a few times a day, the water level in the sump will go start at the Max line, and then go down to the Min line. Sometimes the water level will even below the min line, thus choking my pump, and then after a minute or 2, it will rise back up to the Max line.
This is so frustrating because on more than one occasion I checked the sump level when it was at the Min line, added top off water, only to find that a few minutes later it started to rise and now my sump level is waay past the Max line.
Anyone experience this? How do I fix it? Bad pump? Old system?
Any advice appreciated.
