New to fertilizers & need some help
I have a semi-high tech 3 gallon tank that I set up recently. It has medium/high light, DIY CO2, and dirt substrate topped with gravel and sand. I've been reading about fertilizers, and I think I'd like to start using them on this tank.
I've never used fertilizers on a tank before, since my previous tanks have all been low tech, so I'm a bit confused. I'd like a nice, cheap, simple to use fertilizer that I can buy locally (at Petsmart/Petco). I want to start slow, so I'd prefer to get just one that has most of the extra nutrients a moderately planted tank will need. I know I'll probably eventually need to dose macros seperately, but if such a thing exists, I'd like to initially get a fertilizer that has both micros and macros.
So, I have a few questions...
1. Does anyone have any suggestions for fertilizers? I've heard good things about Flourish. Is it a good fertilizer?
2. Would you recommend liquid fertilizers or dry fertilizers to start?
