The magical ULNS enzyme

Has anyone on here used ZEOzym? My main DT has been set up for about a year and is connected to a smaller tank which was my DT for 2 years which now has caulerpa sea grass and other seaweeds and jellyfish. I used to use tap water, with carbon treatment and sugar to try and remove contaminents and I changed to RO about 6 months ago stopping the carbon and sugar addition. My tanks have cycled through the different algal stages, after changing to RO I added GFO media, I have quite a heavy bioload and my nitrates have gone from around 30mg/L to 2mg/L and my phosphate was always around 1-2mg/L and is now at 0.5mg/L. I paid the price for using tap water. I was constantly getting a build up of green algae on my glass (like a film), checked my light cycle last week and it was 12 hours main lights 14 hours actinics, I have reduced it to 8 hours main lights 10 hours actinics which seems to have drastically reduced the algae. Over the last month I have a small amount of cyano (very black) patches on my sand.

I am wanting to start vodka dosing to further reduce my nitrate and phosphate levels and start ammino acid/phyto addition (and add some SPS when nutrients are completely reduced), but have heard that cyano will feed on the carbon from the alcohol. Would I be best to use ZEOzym to remove my nitrate and phosphate without adding the carbon source, then use vodka later on? or just add vodka and see what happens?

 

get yourself some Bluelife Red Slime Remover. Good stuff, works great.
