Brackish Question

Marine Salt, Instant Ocean is what I use, be sure to purchase a Hydrometer if you do not already have one.

Remember to be consistent and particular of your salinity levels.. There is a different type of nitrifying bacteria for each salinity level, and too sudden of a shift in salinity can kill off all that good bacteria. So make sure you use a system for water changes and measuring salinity levels.

I killed some brackish puffers, doing too large of a water change and not paying attention to the shift in salinity. After the next feeding, an ammonia spike occured. Ammonia is more toxic in a higher pH, and the brackish tank being at 8.3pH, ended the puffers quickly.

Hmm.. I didn't know that.. I'm wondering if that is what happened to my Violet Goby 2 days ago. I did a 40% water change although my salinity was within .002, I wonder if that would have made a differnce. I'm racking my brain trying to figure out why it passed..
