Material and thickness

I am going bare bottom on my Crytal Dynamic glass tank. What material, color and thickness should I put in the bottom to male it look nice and to help protect the bottom of the tank. Thx
 
I used 1/4" white starboard from tap plastics

+1. It was not expensive and you can have them cut it to your exact dimensions. The big decision is color... When I had some sand, I wished I had gone with white since it would have blended better with my sand. But once I converted to bare bottom, I'm glad I went with black. Once the coraline takes over though, it doesn't much matter.
 
I bought 1/8" black acrylic sheet, I plan to use a little coral glue to ensure the acrylic stay in place before rock scape.
 
Two pieces will join together and enough to cover the bottom 48"x30".

My tank is with rim and a brace across the bottom. Can i benefit from using this? It goes between glass and stand right?

no, they are talking about putting a sheet above glass inside the tank to protect the glass (just in case a huge rock falls or something like that, I know buoyancy won't let the rock fall fast enough to break it, but it is more for psychological comfort).

I have the marine board black color too and I went with 1/2".
Acrylic won't work great for this application, and you need to get the marine board.

Tap plastic was a rip off, I bought mine from a whole sale dealer in Hayward, and paid 1/4th of the price what the tap plastic was charging. This place also has CNC so they will cut the sheet to the dimensions that you need.
If you have a small tank then you can go with tap plastic, but if you have a huge tank that has a lot of bottom surface area, then the whole sale dealer will save you a lot of money with which you can buy a coral that may die later... haha
Hope this explains
 
anyone use foam pvc? (the stuff you are supposed to put under rimless tanks) I have some left over from what i bought to put under the tank, i figured i might just use it in the tank as well..

I'd be a little wary of that for two reasons:

1. Who knows what chemicals might leach out of it.
2. It crumbles easily and you could have little while pieces floating all over your tank.

Some people use egg crate, some use plexiglass, some starboard. But to Randy and Maddhugan's point, it's mostly just for piece of mind. The odds of something breaking your bottom pane is super low. If I did my tank again, I'd seriously consider not using anything.

you're thinking white styrofoam, which actually shouldn't be used under the tank, or in...

Yep, you're right. I was thinking white styrofoam which both LeeMar and SPS Coral Store (where I bought the tank) recommended I use under my tank. I went with starboard inside since it's tried and true for not leaching.

Care to share the wholesalers name? Are they open to the public?

starboard from tap plastics co-sign

You can drill holes in it, connect acrylic rods to hold drilled rock to create nice aquascapes.
 
1/4 inch starboard from tap is the way to go. Cost me $25 to get the piece I needed, very reasonable and very durable. Be sure it's a little smaller than your tanks internal dimensions so you don't overlap the silicone.
 
Anybody know the name/contact of the whole sale dealer in Hayward?

I need one for my 4"x2" tank.

Also wonder if white is better than say "seafoam" (slighly yellowish) - less risk of color leeching into the water long term?

Will 1/2" work better than 1/4" thickness for installing rods to hold rocks in place? How do you secure the rod itself to the starboard sheet?

I heard rocks could move in bare bottom tank. Tap plastics has a kind starboard that has a pattern on one side, wonder if that will work to prevent rock movement?

Thanks!
