Hey all. 55 gal
. Filled with (no salt) water added heater, Second Nature Acura 1000. This heater is has temp. indicator that corresponds with temp. value. I use a digital very accurate temp. gauge. I set the temp. for 78 and stayed steady for one week. (on vacation) I added my salt to 1.023, temp. climbed to 80. Is this because of the salt ? Had to turn the heater down to 75, this morning 78 and holding. Just curious if this is normal for heaters and salt.
