... That is profoundly funny @_Maq_ ... Its a long the lines of I keep changing things, but my tanks never gets to be stable... .. I suspect we’ve all been guilty of that at one time or another. As time has gone by the more I realize that stability is the only true overarching "parameter" that makes the difference between success and failure with a planted tank... I know it's a blanket statement that rest on initial conditions that needs to be right within a meaningful range and maintained. Of course, stability will not commingle with the desire and urge to experiment and thats fine, we all have different priorities and objectives with the hobby.Hmmmm... I have to admit that I've tried MANY things, but not this one, yet.
