It took 2-3 days for the media to get enough colonized bacteria to fully tumble but it’s all around an amazing filter and I would 100% recommend. Cory’s video on it I would definitely watch if interested because it’s fairly informative. So far seems to be holding the bio-lode of my silver angelfish pair and silver tip tetras very well
I put in a 60 gallon planted tank in addition to my fluval C4 as a booster. Does a great job! I don’t mind looking at it since it’s always moving and kinda interesting to watch. At first I installed it upside down and it wouldn’t tumble so upon further inspection I noticed the grate I had on the bottom was the top and corrected my misuse and everything started moving as expected after that. Great product
After 3 days my filter media started moving. I use this in my koi fry tank ,where ammonia can build up. Not with this filter ,plus fry are not sucked up by filter. I highly recommend this Ziss bubble moving her filter.
Skeptical at first. I am old school on aquariums. But things has changed so much. It was my first Sponge Pump want be My last. Very good and glad to do business with Aquariumcoop. I will be back soon.
This is my second Ziss filter. This will be used in my 40 gal breeder tank that I'm setting up. I'm using one in my 29 gal
