I am not sure,I did use it and after about 1 wk all my parameters were right where they should be. I had a local LFS
helping me and they agreed that my levels were right.
I then added 3 damsels and a wk later added 1 clown fish.
About 2 days ago I noticed that my levels were no longer perfect here is what they are
PH 7.8 Alk
high Nitrite 1 or above Ammonia 0 Nitrate is 20. Not so good
So I did a 30% water change but they are the same.
I do have some live rock in my tank but not a lot, my blue damsel with the open mouth died during the night.
I wish I had just stuck to the old fashioned way, but I didn't know much and when I asked at the LFS
they suggested doing it this way. Figured they knew more then me.
I am wondering if I should do another WC
Now I see that my lg black damsel is faded, twitching and scratching against things in the tank ... Help
