brightly k
can someone tell me what it is? because i cant read the back of this ada bottle to save my life because i cant read Japanese. what is it used for?

It's a source of potassium (K) and it neutralizes chlorine. It's mainly potassium carbonate.....carbonate in water is what takes care of the chlorine.

so should i dose everyday? or is that a bad idea? im working with a 40 gallon tank.

without knowing your ENTIRE setup I don't want to recommend anything. Use the link above and put in your information and it will tell you how much and what you should dose.

It depends on how you want to dose your tank. EI, PPS. Pmdd etc.
Calculator is very friendly and will give you exact number.

Just put in 40 gallons, click premixed ferts, select ADA Bright K and then pick what you are calculating for.....I don't know your lightning, CO2, etc. to pick one for you.

i think i need dosing 101

Read the dosing regime link in the sticky or go to barr report and read the stickies in the EI forum and ferts forum. The barr report is much more comprehensive/complex.

What are you using for substrate? I remember reading the dosing for Brighty K is 1mL per 20 litres although I've never read the label/instructions, FYI.

Tom Barr did a scientific analysis of the ADA fert line, and without going into details, Brighty K didn't have a very large concentration of potassium at all. This is because ADA relies on their Aquasoil as the main nutrient source for your tanks.

If you were to use the ADA liquid ferts with the EI method (my preferred routine) you would waste a lot of money. My advise would be to use up the Brighty K and the buy dry ferts and using the calculator linked above, create your own liquid version.

1 ml of brightly k into 20l is about 3.6 or 3.9 ppm of k
