Just over a week ago I set my betts up in his own lil tank away from the community tank. I left for a week for work leaving clear instructions for the folks about water changes etc.
Got back today to find a dead glowlight in my community tank, who knows how long it's been there, and on the
betta tank an
ammonia Reading of... Not 0.04 or even 0.4... But 4!!! They've done waterchanfe, not sure how many but they've managed to use up half a bottle of Stress zyme in a 25ltr tank! And not put enough water back in so the filter isn't completely underwater. Grrr, now have to spend my one day off in 3 weeks fixing this mess
Lesson learnt!
