Fert for swords and sag, hi-tech
For the first time, I am going hi-tech. I am setting up a 25G tank with a sand substrate; the sand is a local product, it may have a bit of iron in it and the rockwork does have iron hydroxide staining. The water is moderately hard with calcium carbonate, but otherwise is very devoid of minerals and metals. I plan to give the plants 3 wpg lighting and set up a DIY CO2 reactor. What kind of fertilizer do y'all recommend?
Some of you may want to recommend a different substrate, but I have decided on the sand, for better or worse. Believe me, I spent a lot of time thinking on that!
