Very light and very porous. I bought these to keep in sump and have bacteria ready to go for a quarantine tank if needed. Time will tell how they perform

been using this for about 4 months now, excellent product spend the money on this and not on the plastic ones looks cleaner and the surface area is just insane for the amount of space that they take!

As far as i can tell, these guys live up to their claims and far better than those plastic bio-balls. I originally bought them to use in my AIO Nuvo 16 for added biological filtration but liked them so much I use them in all my aquariums. They fit great in my canister filters on my 55 gal & 90 gal freshwater aquarium, the sump on my 92 gal reef aquarium and in the back compartment of my AIO 16 gal Nano reef.

Works as described. Great way to increase bio - mass in the sump. Easy to work with and stays in place.

Bought a gallon two weeks ago to go in my frag tank as extra biological filtration. Love the way they support the egg crate when spread out. Be sure to rinse prior to use to get rid of dust and fine loose particles. Will let you know how they hold up.

Replaced regular plastic bio balls in my sump tank and what a difference these things made! Zero detectable nitrates! Lots of little critters hanging out between them! With limited space for live rock, these are the next best thing!

I have been using this product for over 2 years. I found them superior to plastic bio balls as they don't clog or cause elevated nitrates.
I highly recommend
You need very little compared to plastic bio balls, surface area of this product is amazing

I've been using this product for my reef tank for over a year now and it's working great. It never needed to be take out and washed, it seems to stay clean without any maintenance. I was worried that the pores would be clogged eventually but it wasn't the case. It does produce some sand like particles that settles under the sump.
A Great Idea By lobro4 on 12/8/2013

My sump has limited space. I am using these in lieu of sand. If they should get too gross, they are easily cleaned and ready to serve again. Lots of porous surface.

From looking at the pictures you would not know just how porous these are. They feel almost as light at Styrofoam which should give you a better idea.
