i just saw one major difference is that these really cheap ones have plastic caps instead of the rubber. That plastic is probably much more brittle and will break much faster. So I just went ahead and purchased the Optimum recommended by @mknauss. Hopefully they will last another 5.5 years like...

It truly is amazing how much the prices vary. Just found one for even less, $116 for 4 filters. A part of me wants to just give it a try, but then I think going with @mknauss filters where I know they won't fall apart within 3 months is probably the safer bet, even if they are double the price...

I just saw these. At $160 for a set of 4 vs $400-500 quoted by the local pool store for original pentair filters, I'm wondering, is it too good to be true? Are there differences in filters (e.g. too restrictive, not fine enough, won't last long) etc. that justify such a big price difference...

That air relief filter has been deformed for a while and never sits properly on top of the pipe. I already ordered a new one. So I guess replace that first and if stuff still gets through then I have to replace the filters? One has a little tear at the very bottom I noticed.

It's pollen season in Houston and I was about to clean my system. The 4 cartridge filters are loaded in pollen. Surprisingly pressure still barely went up at 25gpm. I also noticed a few strings of oak pollen on the ic40 caught on the plates. Is that normal that some minor amounts will pass...

Thanks for the interesting answers. The CYA loss happened already before I slammed. I actually think the slam was necessary because cya degraded, I was too lazy didn't test CYA for 2 months, then realized it was down to like 40-50 ppm which explained why the FC couldn't keep up anymore and...

Hi all. The first 4 seasons of having a pool I experienced high CYA loss of about 10ppm per Month. I read a bunch of posts on it but never a solution. Well this year I decided to increase my chlorine target. I had always targeted 5 ppm for my SWG because I wanted as little chlorine as necessary...

This happened again to me and I think it is due to the pH r0014 solution getting old. I tried side by side with a new one and on the old one if I continue shaking the pH will go from 7.2 all the way to 8.2 after 1-2 minutes. Tried again using a brand new bottle of r0014 and it staid stable at...

Yeah I was planning on replacing all 4 if I can get better flow through them. Right now I need to turn the intelliflo pump at 1800 RPM do get these aerators going well and it takes about 230 watts. I figured if I have lower head pressure, I would be able to get maybe twice as much water through...

Don't expect miracles from the aerators. I live in Houston and my experience is similar to yours. I get maybe 1-2F extra cooling at max. compared to having nothing at all. I have 4 aerators under the deck that fan over the entire pool area, putting out about 12gpm of aerated water. And even...

One of my 3/4 inch plastic aerators - Pentair 8620150 - broke and instead of getting the exact same cheap plastic version, I was wondering if I should get this brass version. Any thoughts on whether brass could cause issues with my salt water pool? It wouldn't be submerged and and most of the...

absolutely, my chlorine consumption is around 2ppm per day despite having toddlers that pee in the pool :ROFLMAO:

Living in Houston I am curious about your statement. My options: - Run the aerator during the day: Air Temp 100F, Dew Point 73F, Pool Water 90F - Run the aerator at night: Air Temp 82F, Dew Point 76F, Pool Water 90F Intuitively running the aerator when the outdoor temp is higher than the pool...

Just wanted to provide an update on this. 1) These umbrellas are much better quality than anticipated. They still look the same and work flawlessly. Great buy back then for $220 each from Amazon. The fabric still has the same color, shows no wear, etc. despite being outside the entire year for...

I suggest reading this article. That little aerator most likely won't make a huge difference. I have 4 built in sprinklers and running those for 12 hours at night reduces temp by about 3-4F from 89F to 85F. Here in Houston the nights are incredibly humid and hot (low of 80F and 90 % humidity) so...
