The idea is great
Ferrdrakon BIO aquatic plant fertiliser | AMOUNT: 0.5 Litres | IMPLEMENTATION: Refill pack
The idea is great, if necessary simply dissolve in osmosis water, I find the fertiliser very good although I fertilise a little less than the recommended amount, Ferrdrakon was already very good, it was worth a try.

Thrilled with the organic fertiliser!
Ferrdrakon BIO aquatic plant fertiliser
I have only been using the bio-fertiliser for a short time, but I can already see that the recurring problems with stunted new shoots on various plants have disappeared.
I also imagine that the fish population is more agile. Of course, I'll have to keep an eye on things in the long term.
Current status: I am delighted

I don't really need to say anything more about this fertiliser. A very good product.
Ferrdrakon BIO aquatic plant fertiliser
I was already enthusiastic about Ferrdrakon. I switched to Bio Ferrdrakon because it contains a little more K. But both products give my 500l scape great, brightly coloured plants.
