No, I don't have any damsels, I'm cycling fishless.. I've been changing water in and out for the last 2 weeks that I've had the tank running.. I've gotten the salinity down quite a bit, but not to an acceptable level yet... It started at over 1.030, so I don't know what the exact reading was, since it most likely was way off the hydrometer's max reading.. So it could of been higher than that. I'm not adding anything until it gets more exceptable, and since I only cycle my freshwater tanks fishless as well, I don't see the advantage to putting saltwater fish, which are at least 10x more expensive through the stress, and chance of burning due to ammonia and stuff...Though now I do have thousands of copepods running around my tank, and lots of tings alive on my LR.. I'm supposing my tank is rather healthy right now.
