Interesting that the clowns are still alive - Brooklynella usually gets them first.
I have a 75g standard tank and a pine stand at the shop here on consignment but it may be more than you want to spend right now (not expensive... lmk if interested).
My weapon of choice is Hikari Ich-X. It's formalin based so it addresses ich, but it also addresses protozoan infestations - which is what Brooklynella is. It also addresses Oodinium and/or Amyloodinium, which can show symptoms somewhat similar to Brook, so if you aren't 100% sure what you're treating, that is a good choice because it gets a good variety of ills that look alike.
If you use that, you must NOT use Prime, or Alpha or other sulfur-based water conditioners - but I also carry Hikari's compatible product for that. Reason I mention that is because frequently people will use Prime to combat ammonia or nitrite that can happen from a quickly set-up hospital tank, and such. So I usually recommend getting both products. I'm not at the shop right now but I'm thinking they're about $7-8 apiece for those two products, in a 4oz size. I also carry the 16 oz bottle of Ich-X - don't know the price off the top of my head but in the $17 range. So it's not expensive but it works well in my experience.
Another member had a similar outbreak recently and I shipped him some and his fish pulled through - he posted as such on my sponsor forum a couple of weeks or so ago.
