I have 2 tanks, one 525xl (139 gal) and one Nano 20gal. I’m a newbie, in it about 6 months... That said, my tanks are doing well.
My son has a fluval, 13.5 gal tank. Does weekly water changes (I make extra saltwater for him), checks water weekly, etc., just as I do. 2 clowns and some snails in tank. All was well until one day, one clown died. Next day the other died. All parameters were in check.
2 weeks later, water was still in check, put 2 new clowns in & both died within 3 - 4 hours.
LFS said to leave fish out for 4 weeks & continue weekly water changes, issue would likely work itself out. Did that.
Fast forward 4 weeks, all water parameters still in check, added 2 new clowns, both dead within 4 hours. Snails are still alive.
I’m at a complete loss here...... any ideas??? Obviously there is an issue...? Testing with Red Sea and Hanna...
No shock when sticking hands in tank, ever.
