I had a little incident about 2 weeks ago whereby my live rock container was constantly over flowing and leaking , this took a while to sort out and obviously lost quite a bit of water
At the same time my top up decided to not to switch off and started to over fill my sump , which I then started to drain water , and ended up doing a mini water change
Obviously all these errors combined must have affected my levels . I was so rushed for time as I needed to leave for a family get together.
the change would have happened slowly on once all the new water plus top up water had mixed into the system
After last nights dose of salt, levels sitting at 1.0203
