Great job so far. You are rapidly approaching the over the hump time for the initial period. Once you get to about 4 weeks or so the biggest threats have been passed. While a lot has been written/said about treating the fish as soon as they arrive, I am in the camp of waiting to see some indication of problems before treating. And if I have to treat anything proactively for imported wild low pH fish, then it would be for parasites and/or worms rather than bacteria. My expreience with the 8 I have had for a while now was that once they can be gotten over the initial stages, they are just like any other angels. They are all pigs who beg for food whenever they see you.
From all I have read and discussed regarding establishing cycling bacteria that can survive acid pH conditions, there are basically two choices. One is to do it yourself which can take several months to get an acid tolerant colony established from those few survivors started at a higher pH (according to Dr Timothy Hovanec). The other way is to get seeding bacteria from already established low pH colonies. I had those lined uo originally but when I learned that H.A.W. was keeping them in the over 6.0 pH range, I reverted to the former method as the drop from my 7.1 tap to the 6.4 it is now at was not drastic.
I am getting ready to call H.A.W. and place my order today. I sure I hope I can do as well with mine as you have done with yours so far. Please keep posting here as things develop.
