Hi guys,

I got a new kent marine phos reactor to take care of my phosphates.

I need a way to limit nitrates besides husbandry. My fuge area is 20% of my display tank volume. What would be my best option for nitrate control?

My two options would be:

1) Harvest Macro Algae in the fuge area

2) Implement a 6"DSB in the fuge area

I cannot do both as my baffles are only 8" tall.

What would you guys pick?

With option 1 it will be more expensive due to usage of lights, electricity etc.

Is option 2 even viable given that my fuge area where the DSB will go is 20% of my display tank volume?

I know the bigger the fuge/dsb the better, so what are your thoughts?

Personally I have both macro and RDSB. I find the RDSB does more for the nitrates than the macro. The problem with RDSB is that you CAN NOT disturb it, otherwise bad things happen.

More replies pls.

Tnx Pmolan. The RDSB will be left alone as it will be in my sump.

BTW, my display is 55G, my fuge area is 11G. That's 20% volume.
