Hi - I'm wondering if anyone can explain what went wrong with my shrimp tank!
Although the parameters for ammonia, nitrate, nitrite were good in my small tank, the pH was high (8.2). This remained constant over a couple of months, so I thought it was ok. GH & KH were 6.
Then a couple of weeks ago the red nose shrimp, them this week the cherry shrimp and finally the nerite snails, died. I couldn't figure out the problem. Then today I emptied the tank. It was up on a bookshelf so normally I can't smell the water. Today when I siphoned it out I could smell a very strong chemical smell and the taste (a quick sampling when I siphoned), was tangy. Not like the earthy smell and neutral taste of the other shrimp tank I have.
Any ideas what it could have been?
