HTH42049 Pool Care 1" Chlorine Tabs, Swimming Pool Sanitizer with Added Clarifier - Eliminates Bacteria & Algae, Makes Water Clean & Crystal Clear, Sanitizes & Protects - Slow Dissolving, 1.5 lbs

These 1-inch chlorine tablets are a great choice for small pools, spas, or floaters. Don’t let the size fool you—these tabs pack a punch. They dissolve slowly and evenly, keeping chlorine levels steady without the hassle of constantly checking and adjusting.Perfect for above-ground pools, kiddie pools, or hot tubs where 3” tablets would be overkill. They help keep water clear, fight algae, and kill bacteria just like the bigger tabs, but give you more control over dosing in smaller volumes of water.They come individually wrapped (depending on the brand), which makes storage easier and less messy. Just make sure to keep them in a sealed container, since they can crumble a bit if exposed to moisture.

I use these in the little ball that floats in my inflatable hot tub. I’m on my third season with it & as long as you use them on a regular basis, they work! No algae, no over powering chlorine smell, they don’t disintegrate too fast so they you’re replacing them too often either.

I’ve been using the HTH 42049 Pool Care 1" Chlorine Tabs for my pool, and they’re awesome for keeping my water clean and clear! 🏊‍♀️✨ These slow-dissolving tablets work like a charm, sanitizing and protecting my pool by eliminating bacteria and algae 🌿💦. The added clarifier helps make the water sparkle, and I’ve noticed a huge difference in water quality, with less maintenance needed over time 🧽🌟. They’re easy to use in my skimmer or a floating dispenser, and the 1.5 lb pack is just the right size for my needs 🎯. If you want hassle-free pool care that keeps your water looking crystal clear, these chlorine tabs are a must-have! 🧴🔒

I have been using older versions of this product for years. I ran out and re-ordered the closest thing available. I first used this version (with built-in clarifier) a few days ago and our spa is crystal clear, spotless... too clear to dip in the moonlight unclothed. I am very impressed, and this took a lot of work out of chemical adjustments every week!

It does have a bit cloud but man that clean but not overpowering is perfect for my hot tub

Fluidmaster Flush n' Sparkle is a great product for keeping your toilet bowl sanitized -- it releases chlorine into the water with each flush, but without chlorinating the water in the tank which can cause degradation of seals and other parts. Unfortunately, Fluidmaster charges a hefty price for every single refill (needed about every 6 weeks in my experience). Instead, you can refill the Fluidmaster cylinder with 3 of these tablets at a fraction of their cost. You just have to pry the bottom cap off of the cylinder, which is admittedly difficult but worth the effort. I use a screwdriver tip to pry and push the cap off. I removed the foam rubber spacer that's in the Fluidmaster cylinder (not sure what its purpose is), and the cleaning system works just great.

Good product

Ran out of chlorine and forgot to get some last week. Noticed my pool was starting to get cloudy last night so ordered these smaller tabs overnight and put them in my pool this morning. I normally get the three inch tabs but I actually like these smaller ones now. Easy to drop in the skimmer and no pungent smell. Love that I was able to order it and have it the next morning. Made my life easier! Pool season is here and I will get more!
