Sand for the tank

[bamburgb]

So later this week I’ll be moving the tank from one location in the house to another, and am thinking I might take this mini tear down as a chance to change out my sand. I currently have crushed coral coarse sand, what would people suggest, also tank is a 180 gallon.

Don’t use salt sand (small), use heavier stuff this way it won’t get blown around

I just moved my 20 gallon to a 46 gallon and am trying caribsea arag-alive special grade. I like it so far. Doesn't move around as much as the Fiji pink i used in my other tanks.

I've also started using the heavier stuff, like crushed coral. It was too annoying seeing little bald spots develop over time from my pumps with fine grade sand. I've heard it can trap detritus easier but I have lots of sand critters and I haven't noticed anything, been using it in my tanks for about a year and it's nice not having to look at sand blowing around or bare spots develop.

I use Tropic Eden Reefflakes.  It’s available in a variety of sizes:

• Aragasnow - 0.5mm
• Tonga Special Pink - 0.8mm
• Miniflakes - 2.0mm
• Mesoflakes - 2.7mm
• Reefflakes - 3.0mm
• Reefflakes Grand Select - 4.5mm

For my tank the 3mm size provides a good balance of not blowing around but still looks nice and snails/shrimp/fish can still work with it for cleanup.

Right now I have the crushed coral and was  now thinking I’ll remove some of that and then maybe add in a few bags of the smaller stuff like Bahama oolite or something similar
