T.A. Nitrate Destroyer experiences?/Vodka dosing questions

[i have crabs]

i found it did work but was too costly on a large tank to be worth it, i went back to large waterchanges, another one i tried i think was called no-no3 and it seemed to work better

Ya, I'm finding on a large tank it's going to be fairly costly, although probably not much more then what I'll have to spend on salt. I'm thinking a few fairly large water changes should help. Unfortunately I don't have a mixing tank larger then 100g and to fill that I'll have to use tap water and prime. Even then a 100g water change is still only 20% I love having 2 large tanks all plumbed together except for when it comes to dosing and water changes
