Complete Fertiliser for Aquarium?
I'm looking for a complete all in one fertiliser for my aquarium.
Mostly I want something that has NPK as well as Magnesium.
There are two products I have seen that I like but unfortunately I don't think they are available here in the UK. NilocG Aquatics Thrive and Aquarium Co-Op Easy Green. When I have checked online they don't seem to ship to the UK only the US. When I check places like eBay the shipping charges are quite high as much as the product itself and then with an extra 30% on top of that (the cost is roughly the same figure in Pounds as Dollars).
When I look at other products I see things like Tetra Plantamin, Easylife Profito, API Leaf Zone, TNC Complete, Seachem Flourish.
The first two I have no idea what they contain as wherever I look they simply don't give that info. TNC Complete I'm not sure why they call it Complete if it only has Nitrogen and Phosphorus? Seachem Flourish seems to be pretty weak and hardly contains anything in sufficient quantities. And, API Lead Zone only seems to contain Potassium and Iron.
It looks like I need to make my own fertiliser unless anyone can recommend something else I haven't seen or considered?
