HOB Overflow Box or Out Pump?

[Midway]

I could always use ball valves in both pumps to decrease or increase the flow.

Yeah...
If you want to adjust them daily.

I tried this on a nano with 2 MJ12's and I'm telling you, it's not possible unless you are ready to adjust daily or more.

Whats the hang up against an external overflow?

WAY more simple than the dual pump idea IMO...

Would anybody know where I could get a good HOB overflow box in Calgary?

Put a wanted post up in the classifieds...
I bet you get a hit or two.

DON'T use the CPR versions, use the LifeReef or similar (Utube version)...
Mine has been going for nearly 6 years without a break in siphon.

You can also find someone who is decent with acrylic to just make you one...

Thanks for all the advices guys. For sure I'm going to go with a HOB Overflow now. You're right two pumps wouldn't work at all.

Thanks again!!
