Fluval Bio-Max
Why are there two different types of Bio-Max?
Why are there two different types of Bio-Max?
The reason there are two types of Bio-Max is that our main source for the replacement rings is manufactured in a different part of the world than where the actual filters are manufactured. The filter manufacturer also has a smaller source for the original Bio-Max and that is used for when the filter is shipped complete with filter material for sale. Replacement Bio-Max is used in quite a number of different filters other than the Fluval Canister units and uses a different material.
We have not found any definable difference between the two materials, our tests have all shown that the biological activity and basic life span of the replacement rings are the same.
