Hi and thanks for the detailed answers, really helpful
I think that it is a combination of new tank syndrome and me trying to feed that Goni. I had that beautiful goni that i was sold for an easy beginners coral. It stopped extending tentacles and then i was sold some reef pulse food for it.
This may have caused a large increase in nutrients and the algae growth
will do some manual removal and increase water changes to 10-20% twice weekly
Top ups - yes RODI water
Water changes - i use natural sea water that i buy from then LFS as many people do here in Queensland - said to be very good but maybe contains more nutrients than i think
Feeding fish - i will definitely divide by 2 and also rince in RO water - wasnt rincing at all
Sump and algae reactor - i am using the inbuilt back sump of the red sea tank for now and have made the challenge not to upgrade to a more complex system before a while. This will be a good exercise in understanding what i need and why
Was actually thinking of adding a bit of macro algae to the tank. Eelgrass and some other macro seem to be sprouting at the moment around where i live and it' be easy to go and get some sprouts, clean them and plant them in a quiet corner of the tank
PO4 binders - i will try to stay away from this kind of chemicals as it seems to defeat the purpose of having a balanced ecosystem
PO4 now reads 0 consistently, but i read elsewhere that it may be due to actual consumption by the hair algae rather than better water quality
blenny - i didnt resist it was too cute, got a baby one so not sure how much it is going to eat
Thanks
A-
