Nitrate removal project.

[nichjon]

I've used the de-nitrate in my canister filter for about 2 months already but Nitrates have not dropped much, then i read about it more and saw that if the flow rate is too fast, the de-Nitrate will only work solely as an aerobic filter, but with flow rates of less than 200 litres/hr, it will function both as an aerobic and anaerobic denitrifying filter.

So what i did was i removed the de-Nitrate from my canister and replaced it with Matrix instead, i then got hold of a small Skimz FR and filled it with the de-Nitrate and added in a simple valve at the inlet to control the flow of water that's going into the FR which was T-ed off from my filter's outlet. My Skimz FR now contains 1.25 litres of de-Nitrate with a controlled flow of only about 20ml/sec which equates to about 72 litres/hr as recommended by Seachem.

I just tested the water from both my tank and the outlet from my FR with the de-Nitrate and both results showed about the same reading of about 40-80ppm as in the attached below. I will post more results very shortly to see if my little project works, so keep a lookout for more updates. I've also included links below about this product.

Happy Reefing.

Here's a pic of my FR filled with de-nitrate. The blue valve controls the flow of water and the small plastic tube is where the water exits and goes directly into my tank.

im using denitrate too . but my nitrate level only less than 5. my father said that u sholdnt read it that way u should put the test tube over the colour . if u can see the colour, its not the measurement but if u cant see it either than its also not. try to get see the outline of the patch of colour.

yup that's what i usually do also, but i placed it like this to show that the initial test results were the same with the white background. I will post more pics of further tests in the weeks to come. Thanks for your tip anyway.

Latest Update, I just did a nitrate test last night, main tank was 20, direct from my de-nitrate FR was 0. So looks like it's working as planned.

might wanna try lowering your nitrate level.good job with the nitrate project

nitrate seems to be dropping slowly, my previous test was about 80 for my tank, so it's already a considerable drop since then to 20 and 0, anyway i hope that it will drop further. Will test and update again very soon.

If any other reefers out there trying this out, i hope that you will upload your projects and results here so that we can do comparisons for the benefit for all reefers here.

Happy New Year to all.
