Well first, I don't see the need for the sand. I know a lot of keepers thathave only Eco Complete and they grow pretty much anything that they want, even the smallest plants with fine roots. If you want to use it, MTS will not overpopulate so bad that they will be an issue if you don't massively overfeed. My Skunk botia loaches eat any snail I throw in there, even MTS.
As for dosing, with that much lighting and CO2, you will need to dose a lot more than twice a week to keep algae at bay. Remember, nutrient imbalances cause algae not just excess nutrients. If your NO3 bottoms out a lot and you have any other nutrients that don't then algae will be a problem as with any other imbalance.
If you want to use the sand go for it, the plants may appreciate it. MTS will be fine in it and the Eco. Just come out once a month before the lights come on and check the numbers. If the numbers are too high then collect them as fast as you can and get rid of them. Most people will pay for shipping for them if not give you a couple extra bucks for them.
