Re: Fertilizing my 30 gallon
Thanks for the post and for using our Flourish products in your planted tank! :-)
I think adding the Flourish Potassium to your tank would be a great idea. Potassium is very important in the aquarium, as it plays many roles in keeping your plants healthy. Potassium activates many important enzymes, it regulates stomatal activity (the pores in which gas exchange takes place), helps with photosynthesis, transports sugars and is involved in protein and starch synthesis.
So again, I would highly recommend dosing the Flourish Potassium. You can dose it 2–3 times per week or as needed (in response to signs of potassium deficiency in older leaves which includes: chlorosis (yellowing), necrosis (death/browning), and weak stems and roots.
I hope this helps!
