I just cannot filter fine dead algae from my pool without vacuuming to waste several times, a colossal "waste", and even then I can't get all the fine dirt/dead algae out.
A fine 1 micron filter is required.
My pool has 2 banks of four water returns.
I checked with Slime Bags, and although I have *zero* doubts at the quality of their products, I just cannot rationalize the total cost of even 4 without having to consult a divorce attorney, and I have become accustomed to my wife, the 3 dogs and 2 cats.
This thread has been enlightening.
But I am taking a slightly different tack, and will report the results upon completion.
I have purchased 5 #2 1 micron 7" x 32" polyester felt bags from DudaDiesel on Ebay, under $40 shipped to my Miami freight forwarder.
I have ordered 10 2.25-3.25" SS hose clamps for $8. By the time all is shipped to the DR, I'll have spent $55.
Rather than fuss with PVC adapters, I'll simply cut the ring from the top of each bag, and singe the fibers to prevent fraying. I'll then simply neatly bunch the bag around each of return fittings that stick out about 1" into the pool, and secure them tightly with the SS hose clamps. I'll then shut off the other 4 returns.
So for under $55, I'll have efficient "slime" filters on 4 returns, with on spare, for $15 less than the cost of one Slime Bag.
Let's see how this works out...
