Hi all,
I'm currently planning out everything I need to setup my first aquarium, which I'm planning on having planted with beginner plants.
I think I've decided on the Fluval Roma 125, since it's programmable lighting really appeals to me, over something like a Juwel Rio. However I'm assuming that the 10W aquasky light that comes with the tank would be insufficient for the plants? I was planning on using plants specifically rated for low to medium light (Vallisneria, Amazon Sword, Hydrocotyle, Anubias etc.), but I was still thinking of supplementing the included light with a second aquasky, probably the 21W model. Would this be enough to grow the easier plants? (FYI I don't plan on using Co2 for now)
Secondly, I've been spending a long time deciding what kind of substrate to use in my tank. I know you can grow root plants in gravel, but I really want to futureproof my tank for corydoras since I'd love to get some at some point, and apparently sand is far better for them. However I've heard and read in plenty of places that it's hard to grow plants in sand since it's so compacted. So since corys love planted tanks, what exactly are people using to get aquariums with lush plants and corydoras?
I was also planning on adding root tabs to whatever substrate I end up going with, and I assume this would be sufficient to fertilize it for whatever rooting plants are in there. Fertilized substrates like Fluval Stratum seems hideously expensive (at least in the UK) so I'd like to avoid that sort of thing if at all possible, especially considering how much I'll need for the tank.
Sorry this is a bit long winded, but I really want to have some confidence in my choices before I start throwing money around. Any knowledge you can share will certainly be a big help, and will definitely help me sleep at night!
