Magnum 350 cannister filter

[robbyville]

Hi all,

Anyone have any experience with this filter? It's being used at a local art gallery. fish are in real trouble (Mostly through excess ammonia).

My question is in regards to oxygenation, does this filter help to add 02 to the water?

Any advice, would be greatly appreciated. I'm now showing them the proper way to do a water change!

thanks,

Rob
