Q & A
How Does GreenClean Granular Work? GreenClean is a granular algaecide with an activated peroxygen chemistry that works through a powerful oxidation reaction to break down algae cells on contact. An added benefit, the process releases oxygen into the water as it works to eliminate algae.I Have Fish In My Pond: Can I Use GreenClean? GreenClean will not harm fish or aquatic life. GreenClean once diluted in water is non-harmful to animals such as birds, bees, and pets.
Can I Use GreenClean On My Waterfall? Yes, as a contact algaecide the granules need to make contact with the algae to be effective. Our recommendation for treating waterfalls is to turn the pumps off, apply GreenClean directly to the algae, and then turn them back on after 20 minutes.
Will GreenClean Affect The pH Level? GreenClean will raise the pH up to 1 unit. Although this will comeback down on its own within about a week. Test pH prior to using and apply in the morning.
Note: This Product is Toxic to Birds in Raw Form

Offer lots of support and traction- perfect gym shoes
So comfortable- they offer a lot of support and I can tell they will last for a long time (and I’m hard on my gym shoes!). I’m actually a female but I sized down and they fit perfectly. I found them on sale and definitely recommend them as they are well worth the price.

Comfortable nike running shoes.
Size: 13, Color: Black/Summit White/Anthracite/Cyber, Size: 13, Color: Black/Summit White/Anthracite/Cyber
Nice and comfortable from the moment that I put them on my feet. Feels like you’re walking on memory foam. You have to buy comfortable shoes when you’re on your feet all day. I do Amazon Flex in. These will be perfect although I have several pairs so that way, the shoe lasts longer. Definitely would buy these in different colors very satisfied.

Good shoe, seems physically big
I really like these shoes. I’ve been able to wear them for about a week now and am really impressed with how they’re holding up. A lot of my shoes start to squeak in a similar amount of time and these still feel like they just came out of the box.
I especially like the heal support, it feels like it’s really gripping the heal nicely
My one complaint is that they seem physically larger than most size 11 shoes from Nike I buy. In spite of fitting the same inside, the actual shoe seems about an inch longer than my other Nike size 11s. It’s not a deal breaker and it doesn’t impact the comfort, it might even make them more comfortable, but they look a bit large on my foot. And if you have a narrow foot, you might be swimming in these.

Can’t Miss Shoe
Size: 11, Color: White/Blue Crystal/Total Orange, Size: 11, Color: White/Blue Crystal/Total Orange
Great looking shoe! Fit to form, I wear a size 101/2 or 11 and I ordered a size 11 and they fit perfectly. Soft and comfortable perfect for walking as I suffer from knee and back pain at 59 years old…. Don’t judge me. Normal width size for me so not sure about the wide fit but the toe room for me is comfortable. Great choice will definitely recommend.

Yes Go Nike!
These Nike men's shoes are very comfortable. It's a pretty versatile shoe. I am able to work out in the gym, go for hikes, walk on the street and run errands all with ease and comfortability. They are sturdy, have good cushion and great support for your joints and back keeping you aligned. They lean on the more narrow side for fit so if you have wide feet they may not work for you. The green around the heal is attractive. The price I paid for the shoes was extremely reasonable making them a great value. I have been using them for a couple of months now and they are still in great shape. Excellent buy!
