Hi all. I'm keen to set up a gravity fed pvc pipe coast to coast weir overflow for my new 250litre tank. (very similar to the setup in this video: ).
I have a couple of questions and any comments will be hugely helpful.
1. Will 25mm (1inch) pipe and bulkheads be sufficient if l have a 1 meter long pvc weir and 2 outlet pipes at each end? Or should l use 32mm (1.5inch) pipe and bulkheads?
2. If l drill a 45mm diameter hole in the back, 45mm from the top edge, would this be safe? The glass is 6mm thick.
Thanks so much! [emoji5]️
