Hello guys!
I found on other forum one phrase of Tom Barr. Here is it: "In most of the higher light(2-2.5W/gal ranges) tanks, I dose 15ppm of NO3 and 5 ppm of Po4 every other day, or 3x a week or so. I use a different trace mix, but add about .5-.7ppm of Fe 3x a week." This is double dose of recomended. Can anyone explain this? Is this safe for fish and plants? What
conditions demands that amount?
