yes i imagine it was when the water was drained from the tank just looked funny on the first pic coz it wasn't at the time when you took the pic now i know every step of your water changes Carol
I was going to ask if the tank was custom built, because it fits the counter perfectly. Is that a dishwasher underneath? Does the washing cycle disturb the discus?
Quick question- when you agitate the water is that permanent? In other words, if I were to agitate a tank of water on Saturday to get it ready for water changes the following week- is that all I need? Or will I need to do that agitation daily to keep the water up to par?
Hmm juss curious but im thinking of doing something much much more easier and simple. if i were to keep a tube connected to the hot water line at all time using PVC would the hot water like some how messed up the PVC???
Agitation releases the carbon dioxide. (The water does not reabsorb the CO2.) Once the pH is stable is stays that way. You don't want to store water for a week. It will grow bacteria. Just make enough for a day or two.
