I love it. I heard a lot about these filters the water is crystal clear...
Purchased the Hydro-Sponge II for my Betta set up (15g tank) and it's working wonderful. The base is plenty heavy to keep sponge filter in one place in a bare bottom tank. Product was exactly as shown, works wonderful and costs a fraction of the price anywhere else. I have been searching for a reasonably price Hydro Sponge for a while!
I have these in all of my tanks, they are simple, cost effect and do a great job. Excellent to add to fry tanks as a seasoned filter provides excellent food sources for fry - they'll latch on to the sponge and eat away.
