Also, since you're growing in basically straight gravel (FloraBase) I would repot it in a mix of your FloraBase and some leaf mould, or a little garden soil. I use a mix of 1 part laterite, 2 parts Aquasoil, 2 parts Flourite with good results. I've also used half peat, half sand successfully and pure leaf mould collected from the woods. Thankfully, pontederiifolia is quite forgiving.

Just wondering how you measure the fertilizer if the plants will be sitting in the water? Would you want it sitting in say... 1/4 strength what you'd normally water with ("recommended mixing rate") then do a water change from time to time or just re-dose or a bit of both (add more ferts every 2 weeks, change water monthly sort of deal)?
Also, florabase is a lot softer than standard gravel, from what I've heard it's a lot more like Aquasoil or similar - you can easily crush the stuff and it's very soft when wet. I'm going to wait on re-potting since I just did a few weeks back and don't want to slow its growth (any more than it is!).
