[The old man]

I am growing Blyxa Japonica in a fairly high light tank using a good substat and using the seachem line of ferts and excel.
It does seem to be doing fine although it seems slow growing and no additional plants have shown up yet. (about a month). Color is good and seems healthy.
I also use the line of ferts in a small lowlight tank with a few shrimp and they doing well. Planning on adding pressurized co2 later this month. Wil see if the Blyxa grows faster.

excel and iron are daily. Flouish, nitrogen, postassium and perhaps trace is about twice a week. You get to skip a day if you do about 50% water change one day a week. There is a schedule on a link somewhere here that you can adjuist for your size tank. For a 50 gallon tank the dose daily for iron and excel is 5ml daily. Except the day after a water change and then it is 20 ml for excel. So you can see it is quite a demanding scheule.
