I've read many sites that promote the miracle grow method... I think if used in moderation and all the nutrients are used before putting into the tank, it should be alright. But I haven't seen any reports to show the side effects, etc. so just postulating...

I have enough F2 to make 20,000L and starter disks if you are looking for some.
That or you can wait a bit and I can just supply you some Phyto.
I am out of town next week so PM me the following if you are interested.
