I purchased this 7 day fish feeder, placed it in my aquarium, and left with peace of mind that my fish were going to be fed while I was away for the week. Upon my return 7 days later, I was shocked to see that the entire crab feeder was intact and the same size it was 7 days earlier before leaving. So, my fish had not been fed because the feeder did not activate to feed them. Fortunately, my fish were still living. I used this brand of feeder before with no issues so why now? I’m concerned about trying this feeder ever again.

Tried this for a 7 day vacation and came back with a tank of super starving fish. My guppies and tetras just did not like it. They all looked super weak and were all just hanging in there until I fed them their normal fish food. My tank water is still pretty clear tho other than the white powder residue.

I'm a realist. I knew leaving a fizzing white block of "food" in the bottom of my tank for 6 days was not going to be pretty just based on the fact that leaving any food in there for 6 days is not great but I was leaving so I gave this one a chance. After 6 days I returned to a white powder across the bottom of the entire tank. The 6 day old filter was covered in an unnatural slime. Ok....to be expected. The fish however looked as tho they aged 5 years. All fins are rotting and they are very lethargic. They look like they are going to pull through fine with the correct water adjustments but it certainly wasn't a vacation for them. Definitely don't recommend and I'll be trying a different brand.

Gone for a week camping and came home and goldfish were alive, water was clear, and pH within range. It was completely gone So the fish must of enjoyed.

This product works great. All my fish are alive. Tablet dissolves over time and there is no cloudiness.

I bought this because I was going to be doing a staycation. Since it is good for 7 days or more and I would be gone only 4 days I decided to put this in early. At first the Corys were interested however after that nothing. The Tetra didn't even bother with this. I figured that they just needed time so I just left it and when I came back it appear that this thing only desolved and the fish didn't like it, didn't even go by it. Then it made my water super cloudy so I had to clean the tank. I will never get this again.

Horrible mess it left while it dissolved in the tank. I have bought 7 day food but never this product. Don't plan to again.

The short story, we left 2 goldfish in a 10 gallon tank, filter on high(its adjustable), lights on a timer. We dropped this in, came back 5 full days later, they were alive, water was crystal clear, no residue, and about 15 % of it was left. Will definitely stock up on this one.
