Clean the leaves out before you start
This is my second year using Green To Blue. I was confused about how to use the product the first year. When I was finished it all made sense to me so this year I was much more successful cleaning my pool. I don’t have a pool cover so this is a three step process for me instead of two steps. 1. Prep you pool. By this I mean take your skimmer and clean as much debris, sunken leaves and such, off the bottom as you can. I had a ton of leaves hidden in that green, murky mess. I knew where the leaves collected and swept every day for a week. Because of the murk I never knew what I was going to drag out. The less debris you have the better this product woks. 2. Use the correct amount of shock according to directions on the box and bag. Filter your pool. 3. After the shock is thoroughly mixed in, pour in the clarifier. Recirculate without filtering for an hour. Let it sit still overnight to allow all the particulates to settle to the bottom of the pool. Set the pump to discharge and vacuum your pool. Mine was so bad I had to shock the pool a second time. The pool was cleaner but not clean. I could see all the settled debris and swept the floor again. The fewer leaves in the pool the better the product works. Repeat shocking, vacuuming, and debris removal until your pool is clean. If this seems excessive that is a reflection of the condition of my pool not the product. I think I could have walked in that water. It sparkles now. Oh, the product does not turn your water blue. At least it didn’t turn my water blue.

Just average
Can't say anything particularly good or bad about it. It's thoroughly average in every way. Nothing remarkable. From my perspective.

All it needs is 24 hours
I buy this every dang year. It works so incredibly well. We were struggling trying to get the pool blue and was recommended this product. With in 24 hours it was blue from being so incredibly dirty. It seemed super pricy but I would pay so much more for this kind of cleaner. Do yourself a favor if you’re struggling to get your pool blues, purchase this product

Wow, what a terrible mess!
Our 25,000 gallon pool started growing algae on the pool walls. I wanted to take quick action as all the grandkids were coming over next week. I evenly applied the 4 packets of "Advanced 1" across the pool, and worked the bottom to ensure all material was dissolved (took about an hour). Then I turned on the recirculation pump and slowly poured the "Advanced 2" packet into the pool skipper as directed. Within 15 minuted the pool pump slowed to 20% due to my 4 large filters being terribly clogged. RESET 1...I stopped the pump, removed the full set of filters, and cleaned each of them with a water jet spray, resealed the filters into their pressure container and reset the pump. RESET 2....Pump pressure and water flow was normal for 30 minutes, then degraded within the hour. I stopped the pump again, removed the full set of filters, and cleaned each of them again. RESET 3....Pump pressure and water flow was normal for first hour, then degraded in 2 hours. yep, had to start all over cleaning out the filters. By now it is getting dark and had to stop for the day DAY 2.....Pool water is still super-cloudy and cannot see bottom drain. Restarted pool pump. It lasted about 2 hours this morning and again clogged. I am hesitant to put in 4 new filters for fear of ruining them as well. So still using my 1-year old filters in hopes of clearing out most of the micro-particulate materials suspended in the water first. Then I will replace filters. I see no improvement in the super-cloudy particulate water but will continue the process. THIS WAS NOT THE PLAN. I only hope I can get the water clear enough for the grandkids this week. The amount of time spent so far is just crazy, and no remedy in sight yet. Some customers are happy, but I will forever AVOID THIS PRODUCT and MANUFACTURER.

Amazing product!!
This worked amazingly!! I opened my salt water pool and it was dark green and I couldn’t see the bottom. I debated draining the pool and starting from scratch, but found this and thought I’d give it a try. Followed the directions, and the next morning my pool was so crystal clear, and the algae looked like thick moss at the bottom of the pool. I used a hose to syphon slowly out into the yard. This was my first time using this product, and I’m hooked, I will definitely keep this in my bag of tricks for future pool opening nightmares. Made it so easy to get the pool clean, and ready to go for summer. And I didn’t waste the extra time and money on emptying, scrubbing, refilling, adding salt, and all that garbage. I will definitely be purchasing this again!
