Saw an ad for the marinepure bio filter bricks, cubes, and spheres. Now according to BRS' overview vid about this product, the bricks have 20,000 sq ft of surface area, and can be placed into a high flow area of sump. Couple of questions i had are;
1. Wouldnt this defeat the purpose of any live rock in sump, allowing for more water volume hence more stable params with same bio filtration?
2.over time im assuming this block will cure the same way rock does, wouldnt the intricate network of nano pores get clogged over time due to biomass being created within rock from nitrifying bacteria? I assume these would have to be replaced on a quarterly basis so the detritus buildup doesnt accumulate deep inside rock? Is it so pourous that the detritus can pass right through?
If anyone is using this product then please tell your honest opinion, and how long have you been running it in your system. I have a nano 20g so this would be a perfect way for me to sell some excess sump rock in trade for more water volume. Thanks
