HI there,
Firstly, please get a QT. They are essential piece of equipment just like your skimmer or steriliser or cannister. It is very cheap to set up and invaluable if you value your fish.
But, lets deal with the issue in hand for now.
Yes I have used Kent's RX-P but I did not use it following the instructions. When I used it is did work, but to prove that it did not work permanently my fish have redeveloped Ich about 3 months later, but now I have a QT and I am performing hypo. So it may work in the interim but not permanently, if at all.
As I said I didnt follow the instructions because I spoke to the Marine Biologist in head of European Operations at Kent Marine Inc. (dont ask how i got his cellphone number, lol). Basically do this: Day 1: One dose of RX-P (as on bottle), Day 2:One Dose of Poly-Ox Day 3: Rest! You must have your skimmer on at all times. Basically RX-P contains pepper extracts which naturally irritate the fish (which is intended - but not nice), so on day 2 remove that by Poly-Ox, a natural freshwater plant extract that will sooth and heal. You might need to do it twice to catch the blighters on the fish, I did.
As I said worked for me, although I may have been lucky. I would always recommend Hypo and QT over this but faced how you are now, this is what I would do.
Garlic does help, its like a vitamin supplement and Ich is a natural repellent to garlic. So it may help, but as I said, prevention is better than cure.
Please seriously consider a QT.
All the best,
Tim.
