Might want to swap with CaCO3 based sand.

This will work fine.

Diatoms: from a nutrient pulse of some sort. Scrub it off and it generally
doesn't come back well unless you add relatively high to moderate nutrients.

Water change. Does great things for marine tanks especially the simple ones.
Easy but cost $ for the salt for the make up water.
More snails will help but it will not solve it completely.

Make sure you scrub. Also, blackouts work on SW tanks also.

I use 4-5 inch base of aragonite gravel they use for sub packing under side
walks here. Cost about 2$ for 100lbs. You might need to look around but this
will help.

The issue with many of the macro's is maintaining the Ca levels and adding
enough nutrients.

Add too much and you'll get blooms of the diatoms but these are not too bad.
Don't add enough and you'll get slime algae.
