Thanks, Bill! My plan is to put one diffuser in the bottom of each cinder block structure (see pic above). I put geotech fabric underneath each one to help prevent them from sinking into the bottom and to help prevent them from possibly churning up the bottom. I’m going to put something between the writes air lines and the cinder blocks to help prevent direct contact with the abrasive surface of the blocks. Perhaps a short pvc sleeve?

It’s also my intention to cut and connect the 3/8” weighted air lines to 1” poly pipe at the water’s edge and run the larger poly pipe all the way (roughly 300’?) to the compressor where I’ll splice the poly back to the 3/8” weighted tube to facilitate connection to the compressor. That was recommended here.

Do you agree with these strategies?
