Good timing. But Ugh... I don't own those test kits.... I own KH, cal, mag, and high PH (test if it's RO water or not with one drop in a tsp.) I can't remember testing NO3 or PO4 in years, don't even remember the test kit. But I did test my mag a month ago I think.
Come on up, I saw how fast you drive. I'll give you 50 gallons of water with a mertens. (haha) But seriously, when I take out a 5 gallon bucket, it's green. Under microscope, it's got all KINDS of stuff moving in it.
