Substrate mixing question

This is where you discuss the conditions of your crabitat -- temperature, humidity, substrate, decorating, etc.

Is this what you are using?

Is the Top Fin white, like a gravel, small stones?

I am thinking these may be too coarse?

One 50 pound bag of sand, added to a half or whole brick of EE works well, and is about 5:1.
In my area, many aquarium sands - besides coral sand - is made out of quartz, which have the added benefit of being totally inert and not leading to diatoms like silica does.

Dunno if its the same in the US, but you'd think it be?

I have a very fine sand. No gravel.

The top fin and super naturals are both very fine sands. I'm guessing I should have used play sand all along. Poo.

Many US aquarium sands are epoxy coated so they are made to be inert, or painted to make them more colorful. (So are almost all gravels, even natural looking ones.) It's not always declared on the labels either. They might not be a huge deal in an aquarium, but being scrapped around while mixing and then by the crabs could easily start flaking the coatings. Uncoated and unpainted sand and gravel tends to be limited to the araginites, but I even bought a bag of that online that turned out to have been dyed pink! The word 'natural' mean nothing unless confirmed with the company it has not been coated.

The supernatural are still all uncoated, but the sand tends to be extremely fine which leads to other issues like compaction.

Would mixing in a batch or two of the play sand/EE mixture rectify the situation? (Play sand 5:EE 1)

Is Quikrete Premium Play Sand the right stuff to use?

Yes, Quickrete is correct!
