Bio Bag Filter Cartridges Medium 12 Pack Review

They work great but you have to pack the bags yourself. It's not difficult, but if you're one of those people who just doesn't want to do the assembly, then don't get this kit.

I have found that I need to add more carbon than the silver packs suggest for the filters to be effective. Also, the price this time was higher than what I paid for the smaller filter box and I didn't realize it when ordering. I'll really pay attention to the price next time I need filters.

Great price! Got 12 filters for about $10 which is way better than the Tetra filters that came as 3 pre-fitted filters for $5. You collect them yourself, but it's very simple. I had to reuse one of the plastic holders from the old filter as this box only had one and my filter needs two. In general, I will now buy theses!

This is my second purchase of this product from this company. I used to buy through Walmart and the cost was higher. Now I buy them in bulk and they work just as well as the off the shelf ones. I placed the green peel in the white bag before adding the charcoal. Then I put the coal in the bag and move it around. Remember to flush before filling the tank. It comes to my door and it makes life easier.
