Orb-3 Self Sinking Aeration Hose, 50' length, 3/8" ID This is in EXCELLENT condition! I literally used it one time! My pool had high Ph, so I hooked up an air pump to a bubbler in the bottom of my pool and used this hose to connect it. I was able to lower my Ph in just over one day, so I pulled everything out of the pool and it's just sat in my garage since. 3/8" inside diameter.

This self-sinking hose is $68 on Amazon. Mine is NEAR MINT CONDITION AND LESS THAN HALF THE PRICE! Thanks for bidding and have a great day!
