Hello, we've had this torch for about 6 or 7 months now... It's been lumpy and bumpy since we've had it. Has anyone else had this problem? What might it be? Thank you! Calcium 520, Alkalinity 180, pH 8, phosphate .25, nitrate 20. Haven't gotten around to getting a magnesium test, but we are saving up to get Hanna Checkers. Any insight is appreciated!!! He does get adequate flow.
