I need help, I am done with my MTS in my planted tank. I just want to know what is the smallest load I can get to get rid of all the mts

A group of 5 or more would take care of most of them. One won't be able to keep up with their breeding. Getting them just to take care of snails is the wrong reason to have them. The will also pop little crescent shaped hole in any broad thin leaves and if you have any shallow rooted plants they may loosen them digging for snails.
They can also live a long time, I've got 4 that are going on 9 years with me. A warning if you do get them, you may like them so much you become a loachaholic.
IMO removing MTS is easiest when using a reverse bottle trap, since they live in the substrate it would take a while for loaches to find them all. Just sink it down with some bait and in the morning you've got hundreds of MTS in a bottle, repeat for a couple days and you won't have any left.Manual is the way to go, even if you don't think it's an option.
I placed a small fish net on the bottom and counted out 100 a day. It won't take long before reaching that number becomes difficult. Then let the loaches finish them off.
