If you've got the stand right against the wall, teevee, it's probably sitting on the tack strip that is used to hold the carpet tight. I think that the carpet layers use 3/8" plywood for the strip, and if you subtract the compressed thickness of the underlay under the carpet at the front of the tank, there's your 1/4".
You should shim it, or you could also just move the tank and stand out from the wall a few inches. You'll have to temporarily drain most of the water first, but it's still an option.
