The AquaBead PLUS System(tm) is completely assembled, plumbed and mounted on a durable, all weather pad that is ready to install when you receive it. Now, that's easy. How easy, as easy as hooking up an AquaBead filter by itself. Hook up is simple, we've done the hard part for you. Here's all you do: Hook up the upper outlet on the AquaSieve Solids Separator Pre-filter(tm) to the line coming in from your pond. Hook up the upper outlet on the Zapp Pure UV to the line returning to the pond. Run the waste line from the multi port valve and you're done. In a space of 36" X 48" for the 3 smaller units and a space of 48" X 72" for the 2 larger units you can have a filtration system that can take care of your entire pond. You have everything that you need on this system: Pre-filtration, Filtration, Pump and UV all in one. Notice that all connections are made with Quick Disconnect Unions. Why is this important? Ask us in a few years if you need to make changes or repairs. With these unions, you won't have to get out the hacksaw and start cutting. Just loosen the unions by hand and then retighten by hand. You'll be glad you chose the AquaBead Plus System(tm). We want you to be happy with your purchase, not only immediately, but down the road, too. We are always conscious of getting maximum flow out of our systems for energy dollars spent to move water. That is why you will find we have used sweep fittings on all water pathways throughout the system. This results in less restriction and allows the use of energy efficient pumps to be used on all of our systems. Less restriction means higher flow through and the use of more efficient pumps means dollars saved on energy usage. All of the electrical components come with plug in cords, so just plug and play. Sounds expensive doesn't it? Sit down. It's only an extra 200.00 dollars above the price of the equipment. You'll spend close to that in parts alone doing it yourself. Tell us you want more info., or give us a call and we'll be happy to explain it to you.
