I was blown away by the effectiveness of urchins. Nothing really even comes close, including turbo snails. Urchins are machines.

So in conclusion the issue is algae and not cyano? How many hours a day are your lights on regularly? You did mention you increased your whites % plus loss of cucs which may have been a combined factor as well.

Funny enough I had gotten my report back from aquabiomics last night -and drumroll please - there is a strong “whiff” of cyano in the tank-or at least when the sample was take in late may.
