Capncapo -
Thanks for the reply. I did try to be very careful when setting up the tank -- and follow the suggested DSB guidelines. My DSB composition is as follows:
Total sand ~300 lbs, enough for 4" in main tank and 1-2" in sump (mainly as a refugium for the critters)
Sand particle distribution
120 lbs 0.22 - 0.11mm
90 lbs 0.27 - 0.14mm
45 lbs 0.51 - 0.27mm
30 lbs 0.92 - 0.43mm
Composition
Si O2 98.20%
Fe2 O3 <0.50%
Al2 O3 <0.50%
Ti O2 <0.50%
Ca O <0.50%
Mg O <0.50%
K2 O <0.50%
Na2 O <0.50%
In addition, I purchased 2 sets of DSB starter kits from IPSF.COM, as well as "live sand" from Bills Reef.com (both of which are recommended on this forum). You do raise a good point though -- I wonder if these have specifically included detritovores. My understanding is that these are worms, as opposed to just pods. I do see quite a few worms in the tank (they are half red/half black-ish with hairs growing all over) -- perhaps, their aren't enough on the sand bed?
In addition, the cyano may be aggravated by a switch about 1 month ago to a fresh food cocktail of shrimps/squid/scallops -- and a switch about a week ago to E. Bornmeman's coral food cocktail.
Any further thoughts would be appreciated - Thanks!
