These are 1/8th of an inch taller and the center hole is smaller than the VI filter that came with the spa, but they fit fine. The "fins", the paper pleats that the water filters through appear to be MUCH more evenly spread than the VI filter that seemed to plug up very quickly. I'm hoping that these 12 I bought will last me a little

These come packaged as 6 packs of 2 each. My portable hot tub was getting a little cloudy and the original filters were fairly dirty, so I ordered a box of these. Replaced the old filters in the evening and everything was crystal clear in the morning. I got about a month out of the original filters with weekly cleanings and using the tub

These DO NOT fit the SaluSpa but can be modified by cutting slits in the top and bottom to fit the filter holder. (See picture) My mistake for not noting that these are S1 and not VI as I searched for, but I don’t think that Amazon should make these the recommended choice when it’s not what I searched for. Also they seem to have

For the past 28 years I have checked our pool’s water using reagents. We’ve never had any major problems, and I attributed that success to a sensitive liquid kit and diligent upkeep. Not too long ago a friend stopped by—he owns a local pool and supply company. He casually asked how we checked our water. When I told him, he

I kept the box in my garage for more than a year and got good results. Then I put it in a resin poolside storage box, which gets plenty of Texas sun for the better part of the day, and in a week or so the strips started giving me entirely different results for all 4 readings. First I didn't make the connection and thought my pool

Does not seem to register chlorine!!
I read reviews on here that these strips keep showing no chlorine present. Well I have to agree. I have a small (8' x 30") easy set pool. I got the strips the other day. Used one today. Showed alkalinity low, and no chlorine at all. None. Though I used bleach a few days ago and it smelled

This keeps my hot tub water sparkling bright. One jar of this came with the hot tub 4 years ago. The tub has an ozonator and I put a Nature2 Mineral Stick in every 3 months. The jar that came with the hot tub (this same size) has lasted 4 years! And I use the tub in all 4 seasons. Using this chlorine is so much easier than fussing

Pick a different brand. The first time I tried to use this chlorine (a few weeks after the purchase, when my old supply ran out) the plastic bottle opened without a problem (with a "child-proof" locking function). When I put the cap back on, then tried to remove it again, the cap would not come off. (The "press-down" function would merely

FINALLY, a test strip that gives both Total and Free Chlorine! These 2 readings need to be as equal as possible or you may need to shock your pool. Pools need enough Free Chlorine (FC) as that is what fights bacteria and potential algae blooms. (Total Chlorine is a combo of used up chlorine and free chlorine) Most strips and OTC reagent

This shock sanitizes and cleans the water better than any other product I have used. We use it 2 or 3 times per week with Silk Balance about every 10 days and that's it. Nothing else needed and the water is clean, smells good, and is very easy on the skin. Please allow enough time to let the shock work. It has a strong chlorine smell

I have purchased probably a half dozen brands of spa shock in the last year and this is by far the best brand and I will be sticking with them.
