kallmond;3672900; said:I fairly simple float switch would negate the need for any pump synchronizing. Have a bigger pump in your sump. When the float reaches a certain point the sump turns on. When the water level in the sump drops to a predetermined point the pump turns off and the sump refills.
The water level in your tank would fluctuate, but it would solve the problem of needing to match pump outputs exactly.

kallmond;3675342; said:But, since it was originally my idea, float switches aren't all that complex, they are in fact plug and play. $40 gets you a pretty nice one from grainger.

bitteraspects;3671675; said:how do you figure an overflow box is any safer or more efficiant than a PVC overflow?
An overflow box is at the same risk of cavitation and shut down as any other overflow system, along with any other risks associated with using a wet/dry system. And since the mechanical function of any surface skimming overflow (be it PVC, box, or drilled) is going to be the same based on how the return/ powerheads/ etc are plumbed, that leaves flowrate v. price.
Since you can build an overflow with a higher flow rate for a mere fraction of the cost, and it will be just as effective and safe to use, seems to be a no brainer.
Then there's the option of building a "bottom siphon" style overflow. While you would need to go with a slightly larger diameter PVC to get that same 1300gph flow rating, the bottom siphon overflow offers all the same functions as the above mentioned overflow systems, but also gives you the added benefit of increased mechanical filtration.
So again, in intrigued to ask. Why is a overflow box "better" than a PVC overflow? Because its more expensive?

Miguel4u2;3675430; said:I did mention that the tubing would look ugly in the tank so thats why i would prefer overflow box. Just my opinion. I rather pay..
Miguel4u2;3671306; said:It is the best,safest, and most successful alternative for a non-drilled tank.
