Review on Seachem 28658 Alert Combo Pack by Anne Franson

The Ammonia Alert is very helpful in teaching my daughter to change the water in her broiler house weekly for her fry and feed to avoid overfeeding. She just has to follow the color daily. And she sees that after a 50% water change, she's turning yellow again. Great tool for monitoring and learning. Warning: Using leaves, cones or wood for tannins in a shrimp tank will stain the pH disc and make color determination difficult. In tanks without the addition of tannins, it is very legible and fairly accurate. I highly recommend it for hobbyists who are just starting out or anyone looking for an easy way to keep track of their day-to-day life. Especially for nano aquariums where the balance can change rapidly overnight or for smaller betta environments. But great for all freshwater setups. The first two are tainted with tannins and need replacing. They do not pass water tests. Includes 1 pH change for 6 months. Be careful not to throw it away! Photos of 3 different installations. The first two are colored with tannins and need to be replaced. Ambient water test ranging from 7.0 to 6.8. Do not use pH charts in a tannic environment.
