Hey all, I will be upgrading my 10g split betta tank to a 20g triple divided betta tank. I have the tank, the lid and the 2 dividers. Now I will be getting a whisper air pump and 33 sponge filters soon. I am looking at this sponge/airpump set kit but with the 3 way level Tetra Whisper Air Pump Bundle and this sponge filter bundle Small sponge filters ideal for Betta fish tanks I am looking at this substrate as the tank will be planted Amazon.com : CaribSea Eco-Complete 20-Pound Planted Aquarium, Black : Aquarium Decor Gravel : Pet Supplies and this light Amazon.com : Finnex FugeRay Planted+ Aquarium LED Light Plus Moonlights, 30-Inch : Pet Supplies Now onto questions: Will the light I get be the 30" as the tank is 30" long? Is the substrate good quality? I've read some good reviews. Will have I have to replace the substrate monthly? Yearly? How is the best way to get it cycled quickly. I will be doing a fish-less cycle and putting the plants in prior to cycle, is that OK? What is a good stand/furniture that looks nice. Something that can hold a 20g. This is the living room it'll go in- it's going where the 10g is.
