Dry fert suppliers

[scubabag]

I run a couple of planted tanks and have a set fertizer mix I've been using now for a number of years. Unfortunately, I can no longer find anyone online to buy from. Can anyone suggest a supplier or am I going to have to change?

My current mix uses:
Potassium Nitrate (KNO3)
Potassium Phosphate (KH2PO4)
Potassium Sulphate (K2SO4)
Magnesium Sulphate (MGSO4)
Abscorbic Acid (E300)
Potassium Sorbate (E202)
Chelated Trace Elements (mix)

I’d have thought you can source all of that on eBay.

All of them are on Amazon too. Maybe except trace. Thought solufeed most likely can be found there too.
