Okay, I got these about a year ago. Put 'em in the sump, but pH issues made me tear down the tank. I didn't know how to clean these, SO I CALLED THE MANUFACTURER, and they told me to soak them in Hydrogen Peroxide. I did so, and stored them in a sealed container. A few months later, I put a few(no more then ten)in the sump of a small SPS frag tank. SIX HOURS LATER, the water was cloudy and my corals were dead (only a few hundred dollars worth). I didn't think it was the balls. Soaked them again and stored them. Yesterday, I placed them in a new 40B frag tank. This morning the tank was cloudy, and the water felt....almost soapy. No ammonia, so I thought I would check the pH. THE pH WAS 11! As in, ELEVEN. Say it with me: ELEVEN! The pH calibration packets are 7 and 10. The tank was at...11! Everyone else seems to have a great experience with these. My pH was at 11! A BRS recommendation and a five star rating are no way good enough for me to ever risk using these again.
MY pH was at 11! Today!

I read about these a while back, then spoke with them at MACNA. I think these are a great product. The balls work great for smaller tanks. I have an IM Fusuon 30L, and filled one chambe. Used the rest of them in my sump on my 315. Plan on getting more

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.

Will never go back to bio balls

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.
