My deep sand bed is working!!!!!!!!!!!!!

I added a couple of inches to me detritus trap (was about 2 inches now about 4) about 3 weeks ago. i have noticed a steady decline in nitrates but didn't know if it was from good water changes (did 2 10% in the last 3 weeks) or from the DSB. i was looking at the substrate today, noticed a lot of small air bubbles about an inch deep up against the glass. i am assuming that this is N03 converted into nitrogen gas. at first i though that it was just micro bubbles from my HOB skimmer but 1 in is to deep for that.

hopefully with some good sand bed maint. and an RO/DI unit next month i'll be ready for some anthozoa action...

 

awesome, always nice to see science at work!

 

What kind of sand did you add? Was it precured?

 

Most of the sand was in the tank when i got it (used from someone moving out of the country). i added a large bag, i think it was 15 pounds of plain argonite sand, and one 5 pound bag of that carib sea live sand stuff, probably didn't do much but who knows
