Ya. The main purpose of DSB is to remove Nitrate. Think my previous post was written in a rush thus the confusion. Sorry.

Hi JC, thot DSB's main purpose is to convert nitrate to nitrogen by the aneraobic bacteria (pls correct me if wrong)? Something very similar to the Jaubert system...
Cos I did see air bubbles popping out from the DSB once a while, and I thot that's nitrogen..
The phosphate burping is something new, thanks for sharing.

solonavi: So would it be correct to assume that a DSB is simply 4-6 inches of sand? And that after a few months the anaerobic bacteria will start converting the nitrates into nitrogen?
Yup. The basic concept is that but a point to note is that the sand has to be fine. Typically, those C0 sand avail in most LFS. The biggest grains are C5.

right thanks
Hi JC, question I have: how does the water get into the DSB for the anerobic bacteria to breakdown the nitrate to nitrogen?
Cos i see it as a big chunk of sand resting below without any aid of "making" the water goes thru it...
I believe it works by diffusion... higher concentration to lower concentration. Cos if you used something to move the water down there you're also bringing in oxygen which stops the process.
Sounds logical to me... thanks Xn!Originally Posted by XnSdVd
best saltwater reef tank i've ever seen..
Hi, do u know anyone who maybe interested in an unuse Oceanrunner OR6400 pump. I bought a 6ft x 2.5 x 2.5 tank and it came with it. right now I am using my tank for plants and small tropical fishes.

Welcome to the club tom! I echo JC's comment...
Hi JC, in a fix now.
My 3 ft marine tank uses undergravel filter, my recent test strip showed abt 25 ppm nitrate (25 mg/litre).
Remember you told me ugf is nitrate factory.
What are my options?
25mg/l is still fine. As long as it doesn't exceed >50mg/l, soft coral should be ok. However, if u are looking for some methods to reduce NO3, maybe u wan to try a de-nitrator or do a external bucket DSB (saw in ReefCentral).

Thanks JC, I am beginning to appreciate DSB... what I am currently doing is water change of 15% weekly, which I can't afford to miss. No slacking.
if have DSB, probably can miss a week and do water change 10% fortnightly?
what's this Oceanrunner OR6400 pump? Is it a sump pump? what's the flow rate?Originally Posted by tomgoh
When ur DSB mature, u can practically dun bother abt NO3. I used to change water monthly.Originally Posted by Darylyap

Its a external pump normally used as a return pump.Originally Posted by Darylyap
