I put a tablespoon of buffer to a gal of fresh saltwater and added it to my 30 gal nano. Some of the creatures are acting a lil funny, not opening up all the way etc. Did i add too much? lfs said i was low on buffer and to follow dirs on container. Directions say 1 teaspoon to 20 or 30 gals so i added too much. Im gonna do a water change today to see if everyone goes back to normal. Gonna buy test kits today too so i can measure it myself.
