acclimate new biomax

I want to use two biomax in my filter instead of one biomax and one carbon.. I also have a sponge filter that they sit in. How do I acclimate the second biomax? Is this recommended? I have a 21/2 gallon tank with one betta fish.. thanks

 

Welcome to the forum

Just so I understand you correctly, you have two filters in this tank? One HOB and one sponge filter? If so, I would think that's a bit too much filtration on such a tiny tank. Usually the sponge filter should be enough because of the tank size.

As for your question, after you rinse the new biomax in tap water, you can just add it right away.

 

Agree with el337. Since you aren't removing your current biological filtration, just add and it will start building up the Bacteria

 

For my information, does the biomax need to go in the filter, or can it go anywhere in the tank?

 

It really needs to go in the filter so it can get the water movement over it to keep the bacteria happy and growing.
