Amazing time saver!
8 years ago
Been around pools since 1976 and fighting algae control without success. After trying numerous products and totally frustrated, thought I'd try this new jar of blue-green crystals. Been using this for over 10 yrs now without any issues.
Definitely beats wasting time/money correcting green slimy pool water! 300 gr jar should last most pool owners 1.5 seasons. It does in my 16' x 32' pool. (using quantity amt from a few yrs ago)--last couple yrs company changed amt applied (about 30% more).
Just an amazing product to keep water clean and clear!
Yes, I recommend this product.

Miracle product !

I've been using this for years in my spa and my pool. Always had issue with the water, especially in the spa. Since I started using this, use less product and water is crystal clear. A bit of Crystalline and Chlorine and forget it. Saves you money and time. Highly recommended..

Effective algecide

I have been fighting mustard algae in my pool with little success. In the beginning, I am sceptical of the little size of this copper-based product. But in the end it really makes a difference. Yet it is not available in the pool supply stores I went; Cantire is the only shop.
Yes, I recommend this product.

Excellent product works well
13 years ago
I have been using for 5 years now. Bought when was getting tired of buying numerous chemicals to maintain pool. Gave it a try and never went back. Cheaper now, was $50 when first purchased.
Lasts 4 months when used as directed on my above ground pool (40 000L): Do not need algaecide , weekly chlorine shock and needs little chlorine.
Be careful that solar blanket is keep free of algae and also pool ladder has no algae buildup. Got lazy couple of times and had to seriously shock pool to recover.
Easy to use: open pool, fill with water, have water tested and buy and use whatever startup chemicals recommended. Have water retested. Then start with double dose of Crystalline H20, then once a week clean poll, backwash then add weekly dose. And that's all.
Yes, I recommend this product.

Q: Can you use this product for salt water above ground pools? Our pool water turned green while waiting for a part for our pump so we are hoping to find a miracle cure!!
12 years ago1 Answer
A: Yes you can use Crystalline H2O with salt system. Put the Crystalline H2o in the skimmer and drop the salt system to the minimum. With Crystalline h2o once a week you can keep the chlorine between 0.6 to 1 PPM only. See the video on web site of Crystalline h2o on how to use it. Salt system is there to produce Chlorine only for bacteria.
