$3 a bottle, 5 cent per tablet, cheaper if I bought the bigger size bottles. I just dropped one into 3 different tubs to see what happens with the plants.
Flourish Potassium™ contains 50,000 mg/L of potassium suitable for the natural planted aquarium. Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium. Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content. In these cases potassium could become the limiting factor to growth. Use Flourish Potassium™ to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.
The most easily obtained sources of potassium are potassium nitrate and potassium phosphate. Both of these sources add to either nitrogen or phosphorus as well as potassium, making it virtually impossible to target a specific NPK ratio. Flourish Potassium™ is derived from potassium sulfate, allowing the user to adjust potassium levels without affecting nitrogen or phosphorus.
from Potassium SupplementThe ingredients in Rexall Potassium 99 mg include:
- Potassium (as potassium citrate and potassium amino acid chelate)
- Cellulose
- Stearic acid
- Cellulose and glycerin coating
- Silica
- Magnesium stearate
- Vegetable glaze
Potassium supplements are available in many forms, including potassium chloride, citrate, phosphate, aspartate, bicarbonate, and gluconate. Potassium chloride and potassium citrate are available over-the-counter and by prescription, while potassium bicarbonate is only available by prescription, and potassium gluconate is only available over-the-counter.
Be careful googling potassium nitrate too. You might get a visit from the authorities.In the past, dealing with a very persistent Cyanobacterial bloom in clean tanks, I was able to 'defeat' the problem with doses of Potassium Nitrate. Buying that has become a problem here, as it was used by right wing terrorists in the US in bomb making, and getting even miniscule quantities of it is a bit of a process.
I remember having good results adding the Flourish one in the 90's compared to what I was getting without using it but as always, seeing is believing which is why i went ahead and tried a tablet in 3 different tubs yesterday to see what happens. I also appear to be lacking nitrate in at least one of the tubs but I addressed that in a different thread. It also reminds me of those people with live plants panicking due to ammonia or nitrite level threads. For at least short periods of time, just leaving the lights on 24/7 until you get the ammonia or nitrite back under control seems like a sensible easy choice. Apparently long term it'll take all your nitrate away as well so.............Most aquatic plants don't flower and don't really need potassium.
