Robarb 71205 Super Blue Swimming Pool Clarifier

This is an excellent blue pool clarifier. My pool was slightly hazy, so I poured in the recommended amount before going to bed. When I got up in the morning, the haze was gone and the pool was crystal clear. It's really easy to use. There are instructions on the bottle to tell you exactly how much to use based on how many gallons your pool is. There are also instructions for dosage when opening your pool. It's also competitively priced with other blue clarifiers and this one seems more conentrated.

Robarb's Super Blue has been around for as long as I can recall, and it's the standard for all other clarifiers, both in performance and packaging. I personally have been using it for over 25 years [primarily when I was in the pool business], and I can't even tell you if Robarb puts out any other products anymore. This is their signature product and money maker. Robarb Super Blue is simple and has two primary tasks: 1) Clump particles together to allow the filter (even sand filters) to remove them 2) Clump particles together so that they are heavy enough to drop out While all this is great for just run of the mill particulate such as dust and dirt, where RSB really shines [literally] is in the removal of dead algae that makes the pool cloudy. You can shock the algae all day long and it will bleach out like your momma's best linens. But it is so small that it flows right through a sand filter and right back into the pool again. You must either make it bigger so that it gets trapped, or so that it falls out. How Robarb works is something I don't know for sure, but I do suspect it removes a positive charge from particles so that they don't repel each other. That is how some air filters work. What I do know is that while there may be other products that rival RSB, none can really claim to beat it. For just bringing back a base shine to your water, be sure to first adjust your pH range to the upper end, at about 7.6, then add a couple of ounces to the skimmer and let it run. You'll see new shine just a day or so. However, if you are in need of clearing up a white pool after killing out a major algae bloom, this product will still work, but all printed directions are completely irrelevant. Following an algae bloom that's been killed off by your sanitizer, check the pH again. It should be adjusted back to the 7.6 to 7.8 range. Then pour 1 full quart per 10,000 gallons of pool water directly into the skimmer. Yes, that's a lot and a lot more than the directions specify. But it's not toxic and won't hurt anything. Let your pool pump run for about 2 hours to adequately circulate the material and then shut off the pump for a full 24 hours. At this point, your pool should be quite clear, but there will be a film of dead algae on the floor of the pool. Adjust your filter valve to the "vac to waste" setting and vacuum your pool in this position where it will pull all the algae from the floor and push it out your backwash pipe. Most as quickly as you can because you are losing pool water every second

I have a 15,000 gallon inground pool that’s sanitized with an ozone ionizer instead of chlorine. My pool turned cloudy 4 weeks ago, and I went to several pool stores during this time, having the water measured and spending 100s of dollars in chemicals. The water balance was okay, but the pool stayed cloudy. Most pool stores in my area unfortunately don’t know how to take care of a pool with ionizer systems. They know how to treat chlorine pools and that’s about it. When their methods and chemicals didn’t make my pool clear again, I did some intensive research and this way came upon the Robarb Super Blue Clarifier. After reading lots of reviews I thought it’s worth a try, and I bought the product. After cleaning my filter cartridge well and measuring my water, making sure it was balanced, I added 1oz per 2.500 gallons to the pool and had the pump run one full day and full night. That was Thursday, and when I got up Friday, the pool looked already much better. I was able to see the bottom drain in the deep end again, but it was not quite clear yet. I waited till late Friday afternoon, but even so the clearness had really improved, the pool wasn’t “sparkling” yet. I went and added more product, this time 1oz per 5,000 gallons, and let the pump run through over night again. When I got up Saturday morning, my pool was in perfect condition again. The water looked silky and sparkled. It was so clear, I could see the smallest sand corns on it’s floor. I am absolutely amazed by this clarifier. It saved me a lot of money, because before I found it, I had resolved I would have to completely drain my pool and add fresh water. As you can see on the pictures (forgot to make “before” pictures, but it really looked bad) my pool is sparkly and clear again. I will definitely add this product to my regular pool maintenance now, and add some of it to my pool once a week, as recommended. This clarifier is a truly a miracle worker if used as recommended.
