Need help on double glass sheet for reef tank

[patmos]

Both of these islands are 1" or more off the sand.

thank you Ron.
BTW what is your sand depth?? i understand I wont find any aragonite or so commercial sand here. I will use a mixture of different sea sand sizes...collected from the sea or remote shore.
No way to import corals here. it's banned, I'll find a way locally. I love the anemones. LPS are more abundant I think

The sand is close to 2" over the entire bottom of the tank.

If you can collect sand off shore, I think it will be better. And it could be very interesting to just put your sand in the tank with saltwater and some water movement and give it a week or two and see what develops. I did it once with a small sample and was shocked at the amount of life that developed.

On the other hand, if you want to get the tank going with corals, it may be better to wash the sand thoroughly with fresh water. Maybe even do a water and vinegar or water and hydrogen peroxide bath for a few hours or a day and then a good freshwater bath. You don't need something from your sand causing issues with corals you may collect.
