In the LFS they recommend 1.020 lowest for my inverts… is that true and is that enough to help my fish to rid ich??
>>I wouldn’t risk the inverts to a salinity that low, quite honestly, I think they were trying to help you with the course you seem determined to take. I believe you’ll lose invertebrates taking this route. Also, there is NO WAY it will have enough of an effect on the ich parasite to be anything but stressful for the inverts. As I stated previously, with ich it needs to be 1.010 (can be a bit lower, but be careful to observe the fish). Since you’re having such trouble with this hypo/fallow thing, I suggest you also search for articles by Steven Pro and Terry Bartelme (I believe Terry addresses garlic use).
