Review on 🐠 Penn-Plax Pro Balance 14-Day Vacation Feeding Blocks Fish Shape (Set of 2) - Optimal SEO-friendly Product Name by John Miranda

Place one tablet in a 20 gallon tank with 2 goldfish and leave for 14 days. My friend checking the house added a new pill on day 8 (said the other pill had dissolved). When I came back from vacation, the second tablet had almost completely dissolved. The good news is my fish are alive and well and the aquarium stays crystal clear. I can assume they ate food. The bad news: I would be uncomfortable leaving the fish alone on these pills for more than a week. They quickly dissolve in my water. Recommendations: If you plan to use these tablets, try them out before you go on vacation. You never know how they will perform in an aquarium until you try.
