Question and Poll!
Debating switching from gravel to sand. I have a 55 gal corner aquarium.
1. How do I know how much sand I will need? Anyone have a calculator?
2. I don’t have live plants but wouldn’t mind some easy ones that don’t require CO2. Is a sand base good or do I need something under?
3. I hear about pockets of gas pockets in sand is that a real thing?
4. Finally, black or natural sand for this setup? Plants have been moved but still similar.
