I Got My UltraSieve and PlayItKoi made it SO EASY!

I had the most pleasant experience purchasing my Aqua Forte Ultrasieve from Ben Cooke at PlayItKoi! The price was right, but I must say that the service was extraordinary. Their website is very impressive, and again, the prices are very competitive. Look forward to diving into the website for my new and improved koi pond. Thanks, Ben!

This is the single best addition that I've made to my pond yet! I wish I would've done this a long time ago. it makes maintanence so much easier. Prior to installing the Ultrasieve 3, I was having to clean my pond and skimmer several times per week. Now, I barely even need to clean it. What a world of difference that it makes. For US based purchases, its easy to install but you will need a 4" fernco rubber coupler (for gravity input) + a 2" fernco rubber coupler (for output) which are avialble at any home depot. This makes it easy to hook to PVC
