2 year cycle - 0 Nitrate .4 Phosphate

[bkpky]

4 days after Chemi-Clean and 3 days lights out there is little to know change. The bit of algae on rock has decrease but this stuff across the sand bed has got worse. Good news is Nitrate is up to 1ppm without dosing. Phosphate is down to .1ppm. Still running GFO and Cheato arrived today and is in the reactor. My wife is taking a sample of this stuff to her work tomorrow as they have a microscope.

Chemiclean did nothing. Been working on PO4 with GFO. It swings often. Nitrates got back to zero fast. Finally got the specimen under a microscope. Interesting video. The bug seemed to be collecting up the stains of algae into clumps. These pictures were taken from samples 24 hours after dosing reef flux.

Chemiclean is an antibiotic that will only work on cyanobacteria. What you have doesn't look much like cyano to me.

Yes, before I went under a scope, some of it was red in the sand bed. Figured it couldn't hurt as I have been at my wits end. I believe the long spell of lower phosphate is starting to turn the tide. Maybe the reef flux is what is helping. All I know is the algae is going away without having to keep the lights out all the time.

Its been a journey the last few months but things have greatly improved. Here is a link to a more detailed journal on my local clubs forum site.

Glad it's improved but I'm not sure why you linked out to your club's forum instead of simply saying that the fluconazole that was suggested in this thread had worked?
