Natural nitrate reduction, reef setup technique

IMO, thick sand, many big pcs of LR. It works for mine, tank with DSB, sump with only LRs and an efficient skimmer.

it's better to hav a DSB with macroalgae as refugium... more effective that way...

[chrislwp]

But you need to maintain the macroalgae in the refugium, need trimming once a mth else overgrown. If you dont trim then the root part will die off. Also 24/7 lights which is $5/mth.

I set up my refugium twice but still tear down due to overgrown. In the end I use it as quarantine tank. I still believe that having an efficient skimmer to reduce the waste before it even turn to ammonia, so NO3 is maintain in that way. Having lots of LR help to convert ammonia direct to nitrogen.

Just 2 cents.
