In the market for an HOB overlfow.. Flooding discussion

[fishytime]

I think your plan to raise the return pump would cause you noise issues....if the return pump is just below the water line in the sump it will draw in air.....if it were me, I would buy a brand new 20g tank and drill it, then swap everything over......the cost of doing this would probably be less than buying a lifereef overflow.......

THanks for all the info guys. I was actually eyeing up the Lifereef overflow box as there are many people that seem to like them.

Fishytime, I agree witht he problem with the noise it could create, however if I did the math right, then the pump will be sufficiently below the surface to ensure there is no vortex created. If there is, I can make a custom vortex breaker and mount it on the pump so I think it won't be much of an issue.

Honestly, I'm probably the biggest advocate of HOB overflows on this site.

The pros and cons of drilling versus HOB has been beaten to death on this site.

If you do a search for "HOB overflow" I'm sure a few heated discussions will come up that have very good, biased information from both sides of the fence.

I will say though I am now on year 2 with my home made HOB u tube overflow without break in spihon (flood).
