This pool is operated with minimal equipment (a filter, a pump, a heater) and a minimum of maintenance. I change weekly 50% water and clean while the windscreen with filter wool (thanks Marc for the tip). The pool cleans itself virtually by itself, because the set double flow can not come to rest the feces. He is long and ground moves by the fish and the sandy soil, until it disappears over the weir into the biofilter. He can then be rapidly degraded. With such a system, almost all problems are solved and needs no further equipment, such as additional nitrate filters, ozonizers, PO4 absorber or UVC clarifier. My fish are healthy for many years, have never had to deal with a disease, algae, I have only very, very few, almost keine.Dadurch that the feces in the filter ends up entsehen little germs and water changes really make sense. The filter has a very long service life, thus stabilizing my little pond.
Thank you Thomas for the good review. The black background you ... I've been thinking long what color should I use, but the problem with a triangular basin is as follows. It no longer comes to the side windows to clean and green algae in front of a blue background does not look really nice.
Topic sand .... which could be a problem, but so far everything is still in order. My theory is as follows .... close Sieblinie-> tightly compacted sand> No recording of org. Substances. I'm watching the time, and if he did not so behaves in how I imagine that, then he flies back out and I'll give you the modest here. OK?
