Re: DIY fertilizer There's a few online sources that you can get dry ferts from. There's rexgrigg.com, aquariumfertilizer.com, and gla to name a few. All of them have combo packs which would cover all of your needs. This will probably run you a little over $20 for over a years worth of ferts. Then browse the fertilizer portion of this forum and read up on E.I. and PPS types of fertilizing. Each one has it's pros and cons. |
