Penn-PlaxPBV14 2 Count 14 Jour alimentation Blocks

I had tested this product for a14 days period before my actual trip and surprisingly it worked well. There was also a huge amount of the vacation feeder block left in great condition. So it was time for my real 21 day vacation. I cleaned my tank 3 days prior to my trip then added one vacation feeder food block in a secure spot of my tank. So it needed to work for a total of 24 days. When I got back my tank was in great shape and there was still food remaining. Down side was my under gravel air filter was really filthy, and there was a layer of white food powder visible on my rocks but that's okay I usually clean it every 21 days. My tank is 2 1/2 gal, 34 inches tall and 6 inches round. It also has a long rooted pothos plant and is home to community of 5 fish. I also covered 98% of the top with press n seal for the trip to prevent total water loss. I figured that at the rate that my tank lost water (about 1/3 of inch a day) coupled with a vacation feeder food block would mean instant thick soup after 24 days. But the press n seal stop pretty much all water loss/evaporation and vacation feeder worked well.

I was gone for a little over a week and used two blocks in my 40 gallon tank. All my fish survived, and my water was still clear. I even tested my water when I got back and everything was perfect!

My fish did survive. No one starved to death. But I left off a star because it leaves so much debris at the bottom of the tank. Looks like a light layer of sand in my 10 gallon.

We have a 10-gallon tank with 2 goldfish and 1 snail, I have used these a couple of times and they do seem to work well. However, after the 14-day feeding period is over, It is good practice to change the water in the tank as they do add extra matter to the water.

These saved us in a pinch when our fish sitter canceled right before vacation. Did exactly what they say! We will use these again! (2 small beta tanks with one fish. One tablet each)
