Wow thanks everyone, three days later there's no trace of BGA after 3 days
blackout and now a full days lighting yay. I did notice my phosphates
seemed to skyrocket from .4 to 1ppm on my waterchange. Is this the BGA
decomposing or could something be out of whack?

Thanks Tom I found a couple of links on google after searching for BGA Tom
Barr yay
http://fins.actwin.com/aquatic-plant.../msg00251.html
and proceeded to do a fairly thorough clean of my plants and doing the
water change. I later found your more comprehensive discussion

http://www.gardenbanter.co.uk/showth...ue+green+algae
I misinterpreted point 1 and 2 in the original discussion and added all
the
traces and NPK before the blackout and realised I was only supposed to add
N
and K before the blackout. Should I start the blackout tomorrow after
doing
another water change to remove all the traces/iron or just see how the
blackout pans out with all the nutrients in the water? Thanks, will my 3
SAE's and 2 otos be okay for 3 days with no light/food.

All you need to do is a blackout for 3 days.
See old post on BGA by me.

I've got a fairly bad case of BGA in my fairly new 10 week old 4'
planted
tank and was wondering if anyone has used 'Kent Poly-Ox, cyanobacteria
control' which is supposed to kill blue green cyanobacteria. Maracyn
is
unavailable in Australia for some medical/customs reason. I was
planning on
removing my prized SAE's and a couple of otos which are the only
inhabitants. It says organic material oxidiser. Does this mean it'll
also
oxidise my plants. Thanks.
