Unfortunately does not conform

Based on the description of the item and the interesting price I ordered this filter system. During commissioning, however, I realized that the pump the water, even at a walk position and manually fill the inlet tubing, can not suck on its own. The system performs its work only if you have been previously filled completely manual and no air bubbles with water. The pump must be switched on immediately before re-forming air bubbles. (This took about 1 hour at the first attempt)

When the system was activated, I unfortunately had to find that in a loud operation (approximately 85 dB) was achieved at best 6 sqm / h output. And this in a completely new sand! At this point I decided to withdraw from the purchase.

Thus, I advise against the purchase of this filtration system. Now I have just 30 euros "more" invested and the new is going great!
