Hi all,
What fertelizer would you reccomend using?
I don't think Profito contains any nitrogen (N) or phosphorus (P), so it isn't really a complete feed.
You can use any complete fertiliser you like, why the plants aren't in the tank. Because the plants aren't in the tank you don't need to worry about the fertiliser containing ammonia, so a liquid fertiliser or powder containing urea (
CO(
NH2)2), ammonium sulphate ((NH4)2SO4), or ammonium nitrate (NH4NO3) is fine.
This time of year I usually go and buy whatever liquid fertiliser is remaindered at "Homebase" or <"
Wilkos"> etc. and I use it for the tanks, house-plants etc.
A tomato fertiliser, or similar, at 1/2 strength, is a good cheap option. If you the volume of water in the holding container you can add it as a dry powder (or liquid). A tomato fertiliser will be high in nitrogen (N), potassium (K) and magnesium (Mg), which are the three most likely causes of chlorosis in new leaves.
Because the plants will need a feed while they are in the tank (via <"
EI"> or the <"
Duckweed Index"> etc) my preferred option would be to buy a complete mix from one of our
<"sponsors"> (other sponsors are available).
