This is my first post, so please let me know if there is a better way to do this.
I have 2 questions.
1. Can I aerate with my automatic pool cover closed?
2. How can I aerate from pool returns that are 4 feet under water and are smooth pipe?
1. My TA is high (160) and I want to reduce it by aerating. I am very safety conscious, and concerned about having the automatic pool cover open for 8+ hours when no one is using the pool or watching to make sure nothing unexpected happens. Even with our fence around the pool, I am concerned. I might fall asleep if I sat alone outside by the pool for 8+ hours. My cover track is under the edge of the coping and about 6 inches above the water line. I was wondering about making something that could aerate in the shallow end front corner and I could keep the cover closed while it worked. There is about 1 inch gap between the leading edge of the cover bar and the end of the pool. I figure I have about 6 inch triangle of air space - lateral and vertical- that I can shoot the water out of PVC pipe to aerate. I plan on putting cover pump (WAPC250 1/4 HP pool cover pump, max 3000gal/hr.) on a step in the pool and connecting a T shaped PVC pipe with holes drilled to shoot the water back into the pool to aerate it. Will this work? Is that enough space to aerate or will the cover on the water negate the bubbling of the water and make no difference in my TA?
2. My pool builder placed the three water returns below the frost line, about 4 feet deep on the side wall of the pool below each skimmer and in the middle between them. They blend in well but I think they are 1.5 inch pipe, no threads and flush with the pool wall. I would love to use my pump to aerate (cover closed) with the T shaped PVC pipe, but worry about the flow restriction of 1.5 inch pipe going vertically 4 feet and damaging my pump. I also wonder about aerating in front of the skimmers and sucking in air bubbles. I have looked at the aeration threads, but no one else seems to have deep, smooth, flush water returns. I can't figure out how to attach anything to the returns. At this point, I am trying not to glue on things that would be sticking out from the pool wall and get broken easily. Since I can't figure out this, my temporary plan is to use the cover pump. Does anyone have some better ideas I could use?
Thanks in advance for the help. I have learned lots reading the forums.
