I bought recently this product. It is high in order. The product is supplied in stable packaging, and is easy to assemble. Even the existing cable is long enough so that you need to connect any extension. Who wants this item but set for aquariums, will quickly run into problems. The flanges for tube mounting are not designed for 3/8 "and 1/2". In order to still use the UV-C light filters one needs 2 pcs hose and screw the 4 pieces together cost as much as a similar product which has the smaller ports serienmäßíg.
For ponds of Berlan UVC Lichfilter is however a cost-effective alternative to the expensive products.
In the power of the lamps, one should note the size of the pond.
