Should I use a fine white sand or crushed coral for my 125 gal tropheus bemba tank?

or should I do a mix of mostly sand with a bag or 2 of coral?

Stick with all sand

why would you say sand? i would think with the coral and the PH levels and Trophs preferring that ph, the coral would be better for that reason. IMHO. that and I've for the coral sand in my Troph and Front tanks. and they seem to love it.

My one and only Tropheus tank has a Caribsea african cichid mix substrate that is mostly crushed coral I believe. The Trophs seem to love it and this tank has worked very well. It is ground finer than the straight crushed coral I've bought at lfs though - that is rather coarse and sharp feeling by comparison.

a mix of lighter/darker?

I say sand because it looks more natural. I used to use crushed coral in all my tanks, I switched over to sand a few years back because of the look and the fact that it's easier to syphon waste off the top of it than it is to vac the coral. IMO coral does nothing to effect the P.H level. Also, all the fish that I keep (featherfins, gobies, sandsifters, Trophs and petros sift through it in a way that they can't with a larger substrate.

Your tap water needs to be quite soft to dissolve any of the calcium in crushed coral, aragonite, etc. This is extremely simplified explanation but it's true. My tap is at 8 and my tanks are the same with or without aragonite. But if you have a tap of 7 then you will see results from a buffering substrate.

I'm in the same position, setting up a 125 tropheus tank,
Sounds like pool filter sand is the best and cheapest choice. Do all brands look the same ? and they come in 50lb bags how many do I need for a 125 gallon tank. How deep should the sand be if all I'm keeping are trophs?

If the stuff I got around here is any indication, no they don't. In a filled aquarium the stuff ended up looking a slightly purplish grey, and I hated it. Try to find a broken bag or ask to actually see the stuff to be certain it'll be acceptable to you. If it is actually sand-coloured it'll certainly be better than what I tried.
I would think one 50 lb bag should pretty much do. I'd start with that and see if you realy think you need more, but I'm pretty sure 100 lbs would be overkill. It doesn't need to be more than 1" deep, and can be as little as 1/2".

Where can I find White Pool filter sand??? is there somewhere online that won't charge an arm and a leg?

silica sand. AKA blasting sand. It's cheap and it looks amazing. I use it in all my cichlid tanks.

I find that sand looks lighter (whiter) when wet and under lights than when dry in the bag.
I had some pool filter sand that was very very white and I did not like it as it showed debris more and it showed algae more.
