It is the oasis BioSmart 16000. I have a small pond with a very strong stocking. I had to constantly vibrate against the algae some chemicals. Through my brother-I was this filter carefully. It runs for a week now and I may be the first time in two years to see the reason for my pond! At first I was skeptical, but only briefly. After two days, the first successes were visible, as were the fish ;-). If unclear, unclean water can I recommend this filter will faithfully! I hbae a small pump with 1600 l / h before and this combination has not even needed three days to make up my "mucky pond" a pond with crystal clear water. Only now I have to buy more plants, so that the fish can hide again, -P
I would give the filter also eight stars, just like the dealer. Thank you !!!!
