Very nice tanks Tommy! For my tank, are you certain spraying with an Excel and water mix is not good, considering I am NOT going to have CO2?
you could mix Excel with water after u filled your tank . But do not recommend spraing it when u dry start . It might kill your plants. Last time I tried mix it ( 1 cap full excel with haft gallon water ) and spray into my tank when dry start then all of my plants died after a week .
