getting hair algae, should I reduce KNO3?
I've been getting hair algae...less since I've started PMDD...but
nevertheless it's there. My nitrate tester kit sucks, the colors don't show up right or compare at all...but I think I have over 10ppm of nitrates (A little high?) Should I reduce KNO3? Or might it be something different. (25-30ppm of C02, 2wpg, 50% weekly water changes, 12 neons, some cats and otos...about 85% planted--fast growing hygros etc) Here's my doses for my 15 gallon tank: twice a week: 1/8 teaspoon of KNO3 1 rice grain's worth of KH2PO4 (still not sure exactly how much is a "rice grain"s worth ) 4mls of Trace mix once a week after 50% water change 1/4 teaspoon of K2SO4 any opinions please let me know! Thanx a lot!! -- Dave Picklyk www.picklyk.com/aquascape |

Keeep targeting 10ppm Nitrate, and figure out how to get an accurate test for Nitrate. Test Iron, as it is the "proxy" for all the other trace elements in PMDD. FYI, I recently switched from Seachem Flourish products to PMDD. Here is my weekly dosing schedule for a heavily planted 72 gallon tank with 3wpg of AHS CF light on 12 hours per day: 1/4 tsp Plantex + B 1/4 tsp K2SO4 3/4 tsp KNO3 30% weekly water change Measured Nitrate level hovers a bit under 10. Measured Iron level hovers in the vicinity of 0.1ppm. I do not dose phosphates, but I do insert 3 whole Jobes spikes per month beneath sword plants, and they contain phosphate. Plants are pearling and growing and algae is receeding. |

getting hair algae, should I reduce KNO3?
Holy crap...some of your dosings are as much as mine! Is that bad? My
aquarium is only a 15 gallon. Maybe I should chop the dosings on half. "Dave Millman" wrote in message ... "Dave M.
