I'm upgrading to a 75 gallon from my 55, and need to add some more sand. I currently have 60 lbs of CaribSea live Fiji Pink, and figure anther 60 lbs should be perfect for what I'm doing. In researching, I've seen a lot of different sands and think I have made a decision but needed a few things cleared up. My sand now is .05-.1mm size, and I'm looking at the CaribSea Aragonite Oolite sugar sized sand. Ok here's the questions:
Anybody use the sugar size sand and how do you like it? Pros and cons...?
Is this finer than what I have?
What's aragonite actually mean, and what does Oolite mean? Are these different types of sand? Any info to clear this up is great!
When I put new sand in, should I put the new sand in first and the old sand on top, or vice versa?
If I rinse the old sand in the transfer will that kill all the BB in it, or does most of the BB stay in the rocks?
With 60 lbs additional, totaling 120 lbs in a 75, how deep will my sandbed be? I'm aiming for 2.5-3"...
Thanks everyone, always helpful!
