I have 4 planted tanks, some more so than others. Only the 55 gallon has co2 and it's just the diy type and not much at that. I can be on the paranoid side as to safety of my fish with additives and had an old bottle of Seachem Flourish, added it to a few tanks and had adverse reactions from some fish. I also used Excel before and lost blue rams in two different tanks after.

Any suggestions on other types of ferts, dry that I can mix myself? I am mixing our hard alkaline well water with our softened so it's half and half, I tested iron and that seems to be ok...
I've researched online to the point my head spins and I can't even remember what dry fert works with what and well.... you get the point.
I'd love to hear if you use any... my new plants are getting yellow... that can mean diff. things but I'd like to get them on track soon.
Also, do you just add the concentration, mixture, liquid right into the tank or do you super dilute it... avoid the fish etc? Seems impossible when they rush over to see what goodies I'm putting in the tank!
Thanks!
