The minimal hashrate you need to have to be added on Willi's pool is 200 GH/s.

If you want to still use it , you can use the same workername as another of your asics connected to willi's pool if you have one (which is >200GH/s), so your shares will be taken into account.

By the way, there is a dedicated topic to willi's pool: https://bitcointalk.org/index.php?topic=5478927.0
