Ich meds are fine at half doses in some tanks but not in others. This is due to differing water parameters. If you must use ich meds watch the loaches closely for the first two hours and do a 50% water change at any sign of major discomfort.TwistedPenguin;3979799; said:I've said it a thousand times-ich meds will kill Loaches. Period. Never ever use ich meds, not even at 1/2 dose. Always use salt and heat only and always for 10-14 days.
There are different white spot strains. Some worse than others. In the german aquarium industry we had a problem with an aggressive strain 5 years ago that we believe came from south america. This strain was worse for almost all species of fish in our shops. The meds didn't work anymore so we beefed up the UV on all our systems. This was the only measure that stopped the problem.
On a personal note I have to agree with others here that the best way to ensure long term trouble free enjoyment of loaches is with the use of UV
