That pic of your little boy and his friend is awesome Mike
I had a similar experience recently however i placed a 100 micron felt bag in the sump and cleaned the glass just before lights off one night. That was the only place algae was growing except for a small amount on the front of the pump guards but if i cleaned it first thing in the morning i could see a visible sheen by the end of one light cycle so i knew something was feeding it despite the low or zero readings i was getting just like you Mike. 3 hours later i removed the algae straining felt sock and left the tank alone. First thing the next morning before algae had a chance to soak up too much phos i used the Elos high res phos kit and got a reading of about 0.060 rather than the 0.010 - 0.020 that normally registers. Nitrates using Salifert registered zero regardless of when tested.
I started dosing nitrate and vinegar two weeks ago and the colors and growth on ALL my acros, especially the ones that have been slightly sulky for a long time has been quite surprising. I dosed nitrate for 8 days and tested at 10. At day 7 i began dosing vinegar and at day 15 i'm seeing almost twice the production of skimmate daily than before carbon dosing and nitrates test at 5 now. Phos reads almost zero as usual but the glass is almost to the point of not needing a clean by the end of the day if you know what i mean. Still want both phos and nitrates lower but it seems that keeping both is important if you want EVERYTHING to color up nicely.
Sorry for the long post Mike but i really think you might be seeing the results of a nitrate starved system with highish phos levels just as i had. I saw improved colors just with the nitrate dosing even before starting the vinegar which surprised the hell out of me. :wildone:
No worries about the long post, I like long posts with lots of good information. I might try what you said and see if I get a reading. Sahin also mentioned (in my other thread) about 36 hours no light then testing. I guess it's a similar idea.
What did you use to dose nitrate? I do have a bio pellet reactor and all in one biopellets on my shelf right now that I could fire up... But I guess if I actually do have 0 nitrate this is useless. Except the gfo part possibly bringing any po4 out. Maybe after I get nitrate up a bit I would start them (similar to your vodka)
