hey guys i'm new to RC and so far boards have been helpfull but i have some questions about my new aquapod 12g. Anyway i filled it with water this morning to mix salt in the tank but i am having a terrible time keeping the temp constant at the temp i want to mix the salt i was wondering what you guys do to keep from having temp fluctuations? the lights arent on because i read that they heat up the tank so i wanted to get salt mixed before running them. Any help is greatly appreciated thanks!
