I feel like I've seen this all before... It's like a really bad reality show, everything in me says turn it off, but I have to keep watching.
Blake, seriously, learn to be appreciate a little wisdom handed your way. When I was a kid in the hobby, I know how tough it was tough to get respect because of age (and I had some knowledge). You don't seem to give a damn about repect either way. This isn't some kiddy forum, most of the people on here are 2,3,4x your age.
If you want to be better at what you do, the tools have been laid out for you, it's time you use them. Everyone's laid out what you need to do, and it really seems like you just want someone to do it all for you. In my opinion, you should get rid of the Aro. But that's about a sure death, too. So maybe it'll turn into an expensive mistake. Maybe you can walk away from this having gained something.
Anyway, here's another tool for the box. Some people use salt, some people use meds, I've always just used heat (83-85f) and daily water changes to get rid of ich in FW. You need to get lots of oxygen in the water through heavy turbulence at the surface. With the water changes (30%) you need to get down in that gravel as best you can.
Do you have a water test kit??? At first sign of disease, test the water. You're feeding him a ton and the water is probably ful of ammonia. There's a problem right there.
This is why you need to hit the books. Learn some water chemistry. Learn the life cycle of Ichthyophthirius multifilis, and learn to conquer it.
This is no dis on the forum, which is great, but this is the type of place where you can get 5 wildly different right answers to the same question. This is not a place for primary education. No-one ever wrote a thesis with a 1st grade education, and someone with no real fish credentials shouldn't be tackling some of the toughest fish to keep.
The reality of the hobby is that all of these guys with real kickass fish and setups have killed/lost TONS of fish over the years. It's all a learning experience and I think your on your way to a yellow belt.
