Hard to rate after 1 day

I like that's it's not high density foam. But you are asking me to review it after 1 day so hard to say. The other item I got, the never clog air stone was a waste of money. The bubbles are so big making a stone that leaks more useful to me. This went in the trash.

Best in the game

Best sponge filters. I decided to get rid of my HoB and just switch over to sponge filters. I have 3 different kinds of sponge filters and this one is the best in the game

Hydro sponge filters

In my opinion, it is the best and only filter to use. You don't need to buy any replacement parts and it is easy to set up and use. Excellent surface are for bacteria.

Love it!!!

I wish this were the default starter filter instead of hobs. This is so much better and so easy to use and just plain nicer all the way around.
