I find that lime number terrifying for some reason. I have no idea what lime would even do in a tank environment. I've worked with this kind of stuff around the yard due to acidic soil and it's never pleasant. I've never used pellet form so maybe it isn't as bad, but the powder is awful.
I'm not here to tell you what to do. It does seem as though the all mighty miracle of Dolomite and the perfect formula to use is being kept secret. Crushed coral is easy. I have Aqua Clear HOB's, so I added a tiny amount to the 10 gallon in a filter bag and a slightly larger amount to the 29, also in a filter bag. If I didn't buy crushed coral, I would have bought substrate for cichlid tanks. It is made specifically to bolster pH and water hardness. It's also tank safe, so no fear of what might happen when something that typically is not found in a fish tank is introduced.
