I've seen a video on youtube about a guy using xenia to export excess nutrients,and it seems to work...

Same schedule here

I recently had one tank with very high phosphates (1.0+), and needed to bring it down, so I could combine it with my other tank (zero phosphates) into a single sump. I was using GFO, but it was too slow.

I then got some Foz Down from Tim, and was able to bring it down in a controlled fashion over 3 weeks, so I didn't shock my system too much. It worked, and I was able to combine my tanks without upsetting my other (SPS) tank. I still have to supplement some Foz Down once in a while, as my GFO alone still can't maintain zero phosphates with the combined tanks. I guess there is still some leaching happening.

But Foz Down certainly worked for me, so I can definitely recommend it.

Interesting, I recently read that Prodibio was supposed to eliminate the need for GFO ? Doesn't prodibio alone strip phosphates without the need for GFO?

Anyway.. I run a TLF with HC GFO as well. I used to use Rowaphos but it was a royal pain in the arse to rinse before each use. HC GFO (from BRS) rinses clean in half the time (probably less) that it took to rinse Rowaphos. If you're going to run GFO in a reactor do yourself a favour and use HC GFO from BRS :biggrin:

ha, one day and so much advice.
I picked up a phosban reactor and some gfo after work today and i'll get that system up and running tonight. I plan on taking it slow, dont want to shock anything since the coral are all doing pretty good right now. Just a little excess algee.

i'll look into that hc gfo for later, but until then i'll just give the normal stuff a little extra time to work.

this forum is great :)

It's only been a month and a half since i started dosing Biodigest and bioptim.after 30 days i checked for P04 it was still readable(hanna checker)so,i started using BRS GFO again,keeps the P04 in checked.

Nitra-Guard BIO-Cubes will do both nitrates and phosphates.

No feeding no stirring. And you can use it in the Phosban reactor or any area with high flow.

from J&L's web page

BIO-Cubes are made from 100% biologically degradable polymers that effectively remove both nitrates and phosphates from both marine and freshwater systems. BIO-Cubes have a very high surface area and contains 400% more carbohydrates than any other brand, making it the best product of it�s kind in the world. Independent testing in real world scenarios, have proven BIO-Cubes to far outperform all other competing products. No other product of it�s kind can compare with the explosive performance that BIO-Cubes can offer. BIO-Cubes are very versatile and can be used in filter bags and fluidized reactors. BIO-Cubes require no maintenance and require no feeding dosages making it the easiest and most convenient nitrate and phosphate removing product on the market. Nitra-Guard BIO-Cubes comes with a free filter bag with every jar.

Bacteria consume the high carbohydrate source found in the BIO-Cubes and form a biomass that absorbs nitrates and phosphates from the water in the aquarium. This biomass is then skimmed out with a protein skimmer or is consumed as a food source by corals and clams.

When culturing bacteria, two of the most important factors that will determine the size of the colony are surface area and food source. BIO-Cubes look like small open celled sponges giving the product a massive surface area. BIO-Cubes also has 400% more biologically available, insoluble polymer carbohydrates than any other product in the world. These 2 factors create conditions that are perfect for culturing and sustaining large bacteria colonies required to effectively remove phosphate and nitrate from aquariums. It is these 2 factors that have made Nitra-Guard BIO-Cubes the world�s best carbohydrate based nitrate removing media. Independent tests that were performed in real world scenarios revealed that BIO-Cubes had the ability to reduce nitrate levels from 60ppm to below 5ppm in 2 weeks while competing products claim to only start working after 2 weeks!
