Having ongoing issues with cyano.
Our tank is a Red Sea 350 (250 litres in display tank and remainder in sump). Current parameters are:
Ph: 8.4
Ammonia: 0
Nitrites: 0
Nitrates: 10ppm
25 litre water change performed weekly.
Thanks to a dubious digital hydrometer, I thought my salt content was a little low however after purchasing a Red Sea refractometer it appears that salinity is in fact too high! We are working to correct this slowly over the next week or so.
Also have a skimmer that is hard at work.
It doesn't seem to matter what we do, as soon as we have vacuumed this stuff up, it is growing back within hours. I have read on many threads and forums that cyano is common in new tanks and settles over time, but I am not sure that our outbreak is "normal" (see photo - looks pretty bad to me!). Would it be best to to persist with water changes and shorter lighting periods or would it be better to go down the chemical path to get rid of it?
