I just read up to page 45 of the monster thread “Birdman’s sand and gravel filter”. Whew!!!
I recently finished building my 2 s&g’s but I have a couple of questions that I cannot find the answers to:
1) Do I use flex pipe or regular PVC from the filter’s output to flow into the pond’s falls? Since each s&g flows at 2000 gph max will just one have enough flow for a powerful waterfall? (The barrel is going to be located about 10-15 ft from where the falls will be.) Waterfall will be about 3-4 feet high.
2) I’m planning to use the second s&g to flow into 2 tpr’s. Is this possible?
Pond will be 12x10 and 3 ft at the deepest.
