Awesome. Keep up on testing daily to make sure your numbers don't get so high. 5ppm nitrites can be deadly very quickly.
That's a lot of ferts you're using. May I ask why? The normal
initial dose for Excel is 5ml per 10 gallons (I assume this was your first dose). So, for 2.5 gal the proper initial dose is 1.25 ml. The proper dose for Iron is 1 ml for 10 gallons, so for you the dose would be .25 ml. Flourish should be be less than 1 ml, also. I did the math for my 10 gallon and I came up with 14 drops as the 10 gallon dose. Not sure for your 2.5.
To calculate amounts smaller than 1 ml, what I did was use my dropper to count how many drops were in 1 ml, then multiply that number by the decimal. For instance, if your dropper gives you 20 drops in 1 ml, and you need .25 of a ml: 20 x .25= 5 drops.
Perhaps your guy was reacting to an overdose of ferts.
