It says it treats 80 gallons but do you need all three packs to treat that amount?

Answer by Chewy • Jul 01, 2019
This media treats 80 gallons per pouch.

I run a Betta rescue and have a bunch of smaller tanks (sixteen 7.5g cubes and two rimless 15 gals). I was wondering if I could divide the media into smaller pouches so it could be used for my smaller tanks? Thanks!

With a Fluval 50 and a 70 do you replace the bio bag with this one? So it would be (from bottom up) sponge, carbon bag, then this one instead of white bio filter bag? Or do you add this one?? Pls lmk. Ty

Answer by Chewy • Oct 16, 2019
The Clearmax can be placed in the same basket as the carbon bag, preferably underneath the carbon.

How often should it be changed?

Answer by Chewy • Aug 01, 2019
You'll want to change the filter when you notice the water in the tank is becoming cloudy or dirty.

Clear Max

Clear Max is a must to maintain good water conditions for fish. It filters Nitrites, Nitrates and Phosphates. It’s recommended to change monthly but I check my water

Helps with algal bloom

My fish tank at work doesn't get cleaned as much as it probably should. Nitrates are always fine but I can tell my phosphates are high when I get an algae bloom

My fish tank at work doesn't get cleaned as much as it probably should. Nitrates are always fine but I can tell my phosphates are high when I get an algae bloom. This stuff lengthens the time between major cleans.

Only lasted for a year.

The motor impeller started to deteriorate after 14 months of using it but yes, it did help my saltwater aquarium clean all the time.
