 Re: Nice Cheap DIY Overflow
It works the same way as any other HOB design. I am not building that one though because of the same reason you pointed out. 3/4" pipe would not flow enough for my setup. I am making the PVC one that Wanye from Reef Central showed. I am making it out of grey 1 1/4" PVC so it should be pretty sweet. I will post some pics later today. |
