Hi everyone. First let me start with my tank info. 29 gal. 4wpg pc lights pressurized co2. I have been dosing a sort of modified EI dosing which I add 3ppm kno3 ,.45ppm po4 , K and of course traces every day. So, weekly I add about 20ppm kno3, 3ppm po4 and about 20ml tmg.
I occasionally see very little BGA on the tips of a few of my stem plants, very little mind you, but still it's sometimes there. My question is, if I know my co2 is 30+ ppm,I have adequate water flow and circulation, is it possible that the 3ppm of nitrate I am adding a day is being used up and that's why I am seeing the blue green algae occasionally? As far as I can tell from reading about bga,it seems to appear because of nitrates bottoming out, inadequate circulation or dead spots, maybe a dirty filter. If everything is in order as far as flow and circulation,filter maintenance, co2 and all other nutrients, should I up my kno3 dosing from 3ppm a day? If so, what do you recommend me raising it to? I don't know what else could be the cause of the bga. Like I said, it is not even close to a real problem, but it does still sometimes appear in very small amounts, only on tips of stem plants.
Any help would be very much appreciated.
Thanks,
John
