Ok, update (a small one).
Yesterday I bought a nice piece of wood (I'll post a photo when I get the time), a 5lt bag of black
Colombo Florabase, some flat stones and a JBL Aquarium Thermometer Premium.
From your replies and, given the fact that I don't want to use any CO2 (or ferts, or carbo), it seems I'll have to try some alternative layout.
I do have some ideas, a plan-B (or C, or D) may I say. I'll keep you updated.
I read a lot about the CO2 thing. As this is my first ever aquarium, I don't want to go that far (at least not just yet), so I'll have to settle with plants that don't require it to grow. Probably
this will thread be my guideline.
Maybe I'll change my tank's default light later on as it seems several people have had it changed and did see improvement with their new lights.
I am still researching the relation between light, hours it needs to be on and the impact this has to plants. All this, while the wood has been boiled once (as per LFS instructions), then kept in the bucket to release its tannins. The guy at the LFS said it might take a good 3 weeks. Maybe I should boil it again? Or maybe I should keep boiling it until it stops releasing tannins?
Back to the layout, for another question.
Initially I was thinking of making a tank with Cardinal Tetras or Guppys. The guy at the LFS said that Guppys will munch my plants happily, even if I feed them with their own food (the Guppys that is). He also said that I could easily add maybe 20 Cardinal Tetras in the tank, which
did sound
a lot to me. So how about adding 10 Cardinal Tetras with 3-4 male Guppys? I'd love to hear your opinions on that!
My apologies for the lengthy post.
