Who Gives A Fish Forums

Hi all, I'm running a 34-gallon tank with 14 easy-grow plant varieties and co2 injections, but I'm struggling to balance my fertilizer - I'm using seachem flourish. The instructions say 5ml a week, twice a week if needed. My question is, if I'm doing 5ml a week, is it best to dose the full 5ml on a Monday and do a weekly water change at the end of the week if needed, or should I break it down into a 7-day program? Currently, I'm doing a small daily dose, so any advice is appreciated.

For me, daily dosing has worked out better. It's a delicate balance with lighting, ferts, and co2, and I've found that breaking it down into smaller doses helps. Algae's a good indicator - it'll let you know if you're on the right track.

I'm assuming the fertilizer dosage is dependent on the types of plants I've got in the tank, just trying to figure out what works best for the long haul and keeping them healthy.

The Co2 injection is a game-changer, plants will want to grow faster with it, so they need more light and ferts to keep up. I'd say daily dosing is the way to go, probably around 1-2ml a day.
