Delivers what it promises 50

The delivery was quick and easy. The structure was a little time consuming, but ultimately straightforward. Although the installation of the head gasket and the tightening of the top plate with the rubber mallet at first glance seems a little rustic, it worked and I got the filter without problems closely. The hose connectors sealing tape is actually necessary, but what one gets cheap at any hardware store.

Ultimately, the pump is just recommended, because they, unlike cartridge filters the pool gets really clean. My water (pool with 6,600 liters) was upset and totally green. Two different sizes of cartridge filter pumps have shown (despite Hochchlorierung and anti-algae agents) had no effect. And also the pool floor Suckers has the cartridge filter pump contrary to the description information does not really work. The sand filters the algae-affected water has become crystal clear again within a short time and the performance of the sand filter pump is on the floor Suckers more than adequate. In daily operation ranges weekly backwashing to get the dirt out of the sand. Despite the higher acquisition price, the filter will probably pay off quickly because the filter sand musss only be changed every three years. The cartridge filter is necessary to constantly change, as they assert itself extremely quickly.

Note the following should be:

- After backwashing may be the final rinse really remember, because otherwise the filter sand is rinsed in Poole, which can be very difficult to remove again,
- The sand filter pump is louder and larger than a cartridge filter pump and also consumes more power (logical, since more Leistun that you also need)
- The timer can not be set on all displayed intervals against the display; However, I have programmed him to a work by 01:00 bis 05:00 clock; that's enough to clean out completely and then disturbs the noise forth neither me nor any neighbors.

I am very happy with the price-performance ratio.
