i have a box of these in a sump in a 30 gallon isolations system. push came to shove and i had to significantly overstock the tank. i use this system for acclimation so i admit it is up and running for about a year. no substrate and a few pieces of live rock ... maybe 5 pounds. i had to place a yellow tang, mimic tang, sailfin tang, moorish idol, 3 scissor tail darts, 3 blue gudgeon darts, neon dottyback, randal's gobies, two spot gobie, lawnmower blenny, and a shark nose gobies in the system all at once. believe it or not.. after 3 and 6 days, the ammonia, nitrate and nitrite levels were perfect. i had those fish in that system for 3 weeks, did 2 water changes and all did well. i know it could only be due to the biomedia that i got this lucky. i am buying more today for my other systems!
Ceramic Dust/Particles By Rick on 6/8/2016

I run a BioCube 14 reef tank and am using these in filter chamber #2; in other words, there is no sump unit separate from the aquarium. This is a bare bottom aquarium set-up (no gravel or other substrate in the tank) so larger-than-microscopic detritus of any kind is clearly visible on the tank bottom. The ceramic spheres do continuously slough-off small sand-like dust that settles on the bottom and is difficult to remove completely. The spheres are located in a trickle filter chamber so there is no tumbling action whatsoever to generate this dust. There is little doubt that these provide excellent biological filtration but the dust factor is just something for anyone running a bare bottom nano w/o separate sump to take into consideration when they purchase. (And, yes I did rinse them thoroughly in accordance with the product instructions prior to putting them into the system).

Looks great, holds a ridiculous amount of water which clearly indicates it has great surface area. Also it aesthetically pleasant to the eyes compared to other surface area media I've come across.

This is a really good product and so far I'm really pleased with it. This is a very very light weight product but it holds an incredible amount of water!

Ive been using marinepure for over two years now. The balls stay clean and are extremely porous! My water parameters always stay in check. Im setting up another aquarium and will be using my existing marinepure. I will be ordering more to replace the existing balls! I 100% recommend this product! Its far superior to the Matrix (pumice) that I used to use. Great product! Its all I will ever use for bio-media!

I bought these because BRS was out of the sheets, but i am not disappointed. They sit quite nicely in my sump and they are easy to move around. A little difficult to stack but that is because they are balls. BRS on youtube once again introduced this awesome product to me.
So far so good By Tbone on 11/9/2015

I think that I could use some more live rock but once u get ur tank up and running, the way u like it , it doesn't seem right to change things around, my nitrates were slowly creeping up so I decided to add these in place of rock, I put the whole box in my sump and it's still early to tell if they are helping or not, but no ammonia spikes or cloudy water!!
I hate to disagree, but STAY AWAY FROM THESE!!! By MIkeB on 10/9/2015

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
