What I find annoying: there is simply no instructions on this product! Not even if the amount of a natural pond, swimming pond or fish pond to be. Only the diffuse statement "natural garden ponds up to 10m ³". From comparable products I have in mind that the bacteria to be added at> 10 ° C or even 15 ° C and for a few hours in the filter "available" should, so without passing. Likewise there is no information about the fact that the UVC clarifier (UV lamp) - if any - should be switched off for 24 hours.! Any hints missing. Too bad. A product is only as good as its application. Therefore deduction of points.
I recommend this product, which is a little more expensive, but mM to more quickly and effectively: Oasis FilterStarter Aqua Activ Biokick Fresh, 500 ml
