You won't see the phosphate and nitrate if it is being converting into
algae bloom.
What sort of water flow do you have on the area? dead spots will have
high co2 and can help algae establish better in some spots than others.


Ironically, it is growing in the area with the most flow....it is
decreasing so perhaps part of the whole cycling thing....or maybe it is
the programme of light deprivation I've had to put in place that is
killing it off.....My problem wasn't the green algae but a dinoflagellate
bloom which I am now slowly getting under control (by a combination of
light deprivation, skimming, blasting (turkey baster), manual removal,
carbon, water changes, willpower, determination plus whatever else you
want to add....but it is a long haul....of course the reduction in these
will almost certainly impact my phosphates and nitrates so a close
monitoring regime is in place....but at least my corals are perking
up....shame it killed all the snails :-( Once under control (I understand
it never goes) I will restock with some algae eating clean up crew....to
be quite honest I can cope with the green stuff all the while I get rid of
the toxic dinoflagellate bloom....

After 5 days I am now seeing good progress....fingers crossed....

good stuff,
I have been blessed with no algae problems for a while
summers coming tho so that could soon change!
