GORNORVA 2PCS Hot Tub Filter Mineral Stick Parts Compatible with Intex S1&VI Filter,Suitable for Intex Spa,Bestway Salu Spa,Coleman Lay-Z-Spa,Coleman SaluSpa(Blue)

I bought these for my above ground pool. Very easy to install, pops right into the middle of the filter, no problem. I've only used it a couple of weeks but so far so good. I have had to use little chlorine so far. I can't say how long they'll last in an 1800 gallon pool, but they seem good

After reading lots of reviews I was skeptical on this purchase. WOW My spa has stayed crystal clear since I started using these. It’s no longer slimy in a few days either.

Easy to use! Just drop it in the filter and the minerals release! It’s Unscented and does not change water color.

Great! Saves on the amount of chlorine you use. Especially now with chlorine price so high!

I love these! You just slide it into the filter casing and it is good to go. I have had my hot tub set up and running for a month and the water is still crystal clear. It uses a little bromide but not as much and everything doesn’t smell like chlorine and nothing is fading from chlorine.

This didn't fit in my filter and said was compatible. It goes into hole but then can't screw filter back on to hot tub .

Seems to help. Water is less gross after using the hot tub a few times. Plan to rinse the filters today and mineral sticks and put back in.

So far so good, water seems clearer and softer.....

Excellent product
