Be careful with brine shrimp direct. Their shipping is high.
There's also angels plus and pets and ponds ship fast
I have small osi packs.
Best I've had is ocean nutrition without the salt. Works fast and super high rate.
Canadian Aquafarm all the way! I have been buying his brine shrimp/salt mixture for a few years now and always have great results.. Great prices.. free shipping.. or pick up in Maple Ridge if you are in the area! Rick is a super nice guy too!
