I thought that sand was supposed to be several inches to keep nitrates down, am I wrong here?
Most people who do not have a DSB
, have other things in place to absorb or utilize Nitrates and covert it to Nitrogen, such as a refugium with macroalgae like Caulerpa, etc... LR
in a tank by itself is just not enough... Nitrates will elevate eventually unless good size water changes take place regularly, skimming is done, or it is fed in starvation proportions...It is inevetable that the decomposition of waste becomes nitrate and phosphate...it is nature.
I guess if you have 2.5 lbs per gal
, total denitrification could happen, however, if it is good quality LR
, you would have a hard time putting all of it in the tank... The heavier/denser it is, the less porous it is and thus less de-nitrification takes place..
's have been proven time and time again to be beneficial just as refugiums, and other means means of exportation have.. The decision is up to the individual and what they want to do... what works for some may not work for others...
