Wow. those Abyzz pumps are crazy expensive! I will have to weigh the cost of one, versus drilling a hole into my glass sump, which I am not keen on doing. Obviously drilling is a much cheaper option, unless I crack the bloody thing. I do have a 3/4" diamond glass cutting bit I could use, along with some bulk head fittings. Would 3/4 be too small for a PanWorld?

The input and output connectors on a Pan World pump that will suit your needs is 1”. So you will need at minimum, a 1” bulkhead. A 1” sch 80 PVC bulkhead will require a 48mm hole saw. A 1” ABS bulkhead will require a 45mm hole saw.

My sump is in the basement and I started with a Dolphin Ampmaster pump which worked great but I wanted to get a DC pump that would not draw as much power as the Dolphin pump. I ended up switching to an Abyzz pump and it really is a great pump. I would definitely recommend Abyzz, expensive but in my opinion it is worth it, they have a ten year warranty as well. Benefits of the Abyzz is how quiet it is and power consumption is a lot better.

While I agree that something like the abyzz is a nice pump, it’s really crazy expensive. OK, maybe it does draw less electricity, but do the math. It may be that you’d have to run it for 50 years to break even ( and of course no pump lasts that long).

Thanks guys. The sump that came with my tank is glass, and does not have a bulkhead. I prefer not to attempt drilling one. Can I just plumb the pump into the sump by going over the side via PVC without issue?
You can feed an external pump with a U tube going over the side of the sump, but it’s far from ideal. U tubes can trap air during back siphoning thus not allowing the pump to prime and restart properly. I agree that grinding a hole is the way to go. If you do go the U tube route, it’s about the only time I’d recommend a check valve.

Crazy expensive, yes. More than my first car. It is not for everyone. In my case, the performance curve fit nicely, and I wanted a variable speed submersible pump that I could count on for years to come, even through a potential upgrade from a 220g to something bigger some day. I did consider the largest Red Dragon, which is also a great choice, but I think the Abyzz gave me more potential.

Had this same problem to solve. Large Fluvals, Mag 36 (backup), AmpMaster, Iwaki and PanWorld all were really good.

All DC pumps failed for me - just tried a few until I "got it." I never tried an Abyzz and likely never will since while they are less wattage, they are not that much less wattage and the return to save a few pennies per day is many, many years. I do appreciate the 10 year warranty, but I once had a 50 year roof and the company went bankrupt after a few years when they all started to fail - if somebody would guarantee me that Aybzz would survive the next downturn that took out the last large batch of reefing companies, then this would be a big factor - Dolphin, Danner, Iwaki all made it the last time.

Does anyone know how Head pressure works with 2 return pumps in the basement? For example 2 vectra m1 with a 12 foot head pressure! How would that turn out?

Assuming each pump is running its own return nozzle into the tank, I would imagine that you would plug your numbers into this head loss calculator, then multiply by 2...

Basement Return pump for me will be for a 400 gallon display tank.. Given the size and pressure I am fine with 3-5X Turnover. I prefer 2 pumps for redundancy and ability to clean one without shutting down the system. One task on my current system that I just never did more than 1 time per year was clean the M1. My vectra m1 will be used on a closed loop drilled in eurobrace and feeding a pair of seaswirls to the front of the glass. I can also switch out to a Vectra L1 or add on m1 to each seaswirl since I will have a few extra holes on the closed loop

Any other suggestions on the return pump? Should I just dust of my old mag pump ?
