 Works great -- test your water, remove trayApr 13, 2010
By stevegt
I did a 5-day test; I removed the foil, dropped the tray of food in the tank; the fish all instantly attacked it in a feeding frenzy (I hadn't fed them yet). Went out the first day, came back, noted that the fish were satiated, were only pecking at it occasionally. By this time, the agar had swelled a little, making a film of white on the food block. This might be what some reviews (here and for TetraVacation) are calling "mold". It's not mold, it's agar; inert as far as the fish and tank water are concerned.
Then I re-read the reviews, and realized that an extra comma in the instructions made me miss the fact that I was actually supposed to remove the tray from the food as well. Took the tray with food out of the tank, flipped it over, and the food block fell right out -- soaking in water had loosened it. (The only reason I can see to remove the tray is to prevent it from being flipped over by a bottom feeder; that would make the food inaccessible, as one reviewer noted.)
As of this writing, it's 5 days into the test. Most of the food block is left, I still see the fish eating it now and then, their bellies look full, they're pooping as usual, and they're acting normal. The tank water has never been better; ph 7.0, ammonia, nitrites and nitrates all zero. I haven't been feeding them anything else during this time.
So, it looks like this thing works. Reading these reviews got me so paranoid that I was afraid to try it. But as far as I can tell, many of the reviews are misleading -- either they didn't remove the tray, don't know what agar is, don't test or maintain their tank water quality, or maybe overfeed their fish in the first place. I'll reserve the possibility that maybe only guppies like this stuff, and other fish don't -- no way for me to test for that.
10 Gal tank of about 10 guppies, ranging in age from fry to adult, hang-on-tank filter pulling through undergravel filter (using the undergravel as a prefilter and biomass). Heater set at around 77 deg F.
Recommendations for the folks who make Tetra: You've got a good product here, and I'd like to keep using it. It would be a shame to see it not sell well; as far as I can tell, it's much better than the plaster blocks. Here's what I'd do:
(1) Rewrite the sentence "Remove foil seal, and tray, drop...". It's too easy to misread that. Try instead something like: "Remove foil seal, remove feeding block from tray, then drop..." Maybe add a hint about soaking the tray in water if it's difficult to remove.
(2) Add a sentence about the agar, so people know what to expect in appearance.
(3) Add a whole paragraph about water quality and temperature. I think some of your critics might be getting poor results because they're trying to leave their fish untended in an unfiltered bowl, or in a tank that is poorly maintained.

 My hungry fish hardly touched itMay 26, 2008
By Anthony Chee

I was really hoping that this would work for my goldfish. My goldfish have voracious appetites, and at first I thought that they might eat it all up and get really sick if I put the whole feedder in the tank. I decided to try it out before I went on vacation. After leaving the feeder in for two days, they hardly touched the food. The product has been in my tank for 4 days and it has not clouded the water, but my fish are not eating it.

Didn't work, but maybe your fish are smarter than mineMay 11, 2008
By A. Pleasants
"Music Lover"
I gave this 3 stars instead of 1 because it worked exactly the way they said it would (didn't cloud the water, didn't dissentigrate, lasted). The problem is, my fish wouldn't eat it. My Molly nibbled off of it the first day but not after that. My Platy never even recognized it as food. I finally gave up and bought an EHEIM FEED AIR AUTO FEEDER that I love. If you get this PLEASE test it before you leave town.

 DON'T BUY THIS PRODUCT!!!!!!Mar 08, 2012
By Judy H. Strickland
"Waycross48"
I bought the 14 day vacation feeder for two 4 1/2in long Carandas for an upcoming one week trip. I decided to test it over a 2 day weekend since I'd never used one before. I put in a new filter, the water was crystal clear, as always and everything was spotlessly clean. When I returned 48 hours later, I could barely see my fish in the water!!! I was scared to death that they would be sick. I immediately had to change out 2/3 of the water. The bright blue clean filter I had placed in two days earlier was now BROWN. The bio filter was FILLED with thousands of tiny particles of food. It was the biggest mess I've ever seen in my life. It looked like an aquarium that been left for weeks unattended - HORRIBLE is the only word I can think of. I keep my tank crystal clear, clean and free of algae. I use ONLY Dr. Tim's aquarium products and they can bring a tank like the one I came home to, back into proper levels overnight. The fish are for my grandchilren and I love them also. They are attached to me and will eat out of my fingers. I nearly cried at the thought of loosing these two gorgeous fish. STAY AWAY FROM THESE WEEKEND BLOCKS OF FOOD. GO WITH AN AUTOMATIC BATTERY OPERATED FEEDER. MUCH EASIER SINCE YOU CONTROL THE AMOUNT OF FOOD DELIVERED EACH DAY.

 works great for me!Oct 24, 2011
By k10
i have 5 gold fish and have used this product multiple times when going on vacation. when i come home after being gone for 5-7 days, sometimes nothing is left of the food, and sometimes a little gelatinous goo is left, but it doesn't pollute the tank at all. my only concern is that my fish seem lethargic and it takes a while for them to come out and eat normal food, but that might just be because they've been lonely. i'm just happy to come home to find them alive!
