Learn from my mistakes, don't waste all your time & money this summer. Here is how I cleared my brown iron infested pool up in just 3 days! We decided to attempt to set up a pool again this year & I forgot how tedious the whole process is, but this filter ended up being a savior! I decided to start small and ordered the 8ft intex pool from Target (99$) & although it claimed it came with a filter pump it didn't. I figured it was a small pool so I could get away with a small pump so I ordered an off brand 330 pump ($79). We have a septic water system so our water is full of iron thusly when we filled the pool it was super cloudy and murky. I hooked up the small filter and ran it for 10 days straight, cleaning out the cartridge daily and adding chemicals constantly...the water was slightly better but still very cloudy and brown (see 1st picture) and the iron particles that would settle on the bottom were too fine to vaccum up. After doing some research & reading a ton of reviews I decided to buy this filter. I knew from the reviews I needed to buy the adapters since I have a smaller pool, I got them for $16 here on Amazon. I read the gasket is not necessary & since it was a $60+ part I decided to hold off on that. While it works great without it it enables you to turn the water flow off for pump maintenance so it is helpful, I think eventually I will be getting one. The adapters are 100% necessary as the fittings are larger than the pool. So the filter & adapters came in just 2 days. It was super easy to install, took me like 30 minutes to do myself. If you're like me and super new to pools intex has some videos on YouTube that help a lot! I will admit the dual suction threw me off since the smaller filter only had 1 intake 1 output. Initially I installed it backwards & had 2 output hoses and 1 intake hose. The next day I realized my mistake and switched the hoses to 2 intake and 1 output. But, it still worked well that first night, that's how amazing this filter is. Being that my pool is so small this filter is super powerful!! The suction power is amazing & the output comes out like a hot tub. That old small pump didn't even move the water around, this one actually circulates it. If you're like me and have hard water or iron issues Google "pool sock method". I filled socks with pillow stuffing and zip tied them to the output hose than rinsed them clean a few times a day. The helped to collect those tiny stubborn iron particles. After the 1st night of running this filter the water was 80% clear (see 2nd picture). I was pleasantly surprised!! I continued using the pool socks and shocked the water the next day & it was 90% clear (see 3rd picture). After a few days of maintenance, chemicals and the occasional vaccum (I have one of those cheap pool vacs that hook up to a garden hose), I went outside to find the water 100% crystal clear!!!!! Literally all the iron particles GONE!!! Since it was super hot here last week the water feels amazing!! I feel like I finally conquered my greatest challenge yet...the brown pool water, and I owe it all to this filter!!! Yes it was a little more than I initially wanted to spend for a little pool, but it was SO worth it! I wish someone would have told me that before I wasted money on a subpar filter & weeks of having a brown pool no one could swim in!! Now that I have this amazing filter and know it works so well I plan on upgrading to the 12ft poolnext year... I just have to level out the ground better... (if you haven't put your pool up yet, LEVEL THE GROUND 1ST it really matters). But for now we are LOVING our little pool paradise. So if you have a small pump the upgrade is 1000% WORTH IT!
