I could only see something like this if you were using freshly made rock, or dry reef bones and base rock, even then it wouldnt be necessary if you added LS.
But then again Ive heard worse, like the guy who stood up on his tank and ..... you know :rolleye1:
Could always dose a shot of phyto too to beef up the nutrients, that way the fauna has something to munch and spread, and what doesnt get used up will vamp up the joo joo you need, I'd think, I did it but have no bases of measuring the results, although I was surprised how quickly my 30g started up, much faster than the 50. Coulda been just good rock and a deep sandbed for all I know though.
