A warning to anyone thinking of using frozen food bags to cool your aquarium

Hi folks
Yesterday my tank hit 30 degrees and the Mrs decided to put an apparently sealed bag of frozen Brussel sprouts into a 240 litre tank to cool it down. I came home late from work, all seemed well and I just went to bed and didn't pull the bag out.

This am the tank was milky and stank of Brussels sprouts fart. I've done a 90% water change, but have lost a few young fundulopanchax gardneri and this rest are gasping.

The bag still looks virtually sealed but there is a small breach in the heat seal which has been enough to let water in and pollute the tank.

A warning in case anyone is daft enough to do the same. Mr Freeze ice pops on the other hand are fine, but upset the kids and the Mrs when they are not free to be eaten. I hate Brussel sprouts even more now.

brussell sprouts are without a doubt the worst "food" ever. this just further proves my point. i normally put a few cubes of ice in a plastic ziploc. and just float it around. never had any issues.

For the next time, put a few Pet bottles filled with tap water in the freezer. :)

Most of the time not doing anything is best. Cool the room (open windows in evening/close blinds in day), add air to the tank to increase oxygen and sit it out. Mine was up at 32 late yesterday and even the shrimp are fine. I think people often do more harm trying to yoyo temperatures than just leaving it.

You need to do some serious managing if you want to keep the temperature lower and stable. Even more so if your aiming for below room temperature.

You can easily shave 2-4 degrees from a tank's water temperature with a decent fan blowing across the waters surface, and it is much more stable than adding frozen items. The price you pay is increased evaporation, but that is easily solved with a jug.

At least the brussel sprouts ended up in the bin - arguably the best place for them! 🤢

Thanks for the suggestions. I've got 9 tanks. 3 display and 6 breeding tanks. All the ice cubes we had went in the little breeding tanks. On my day off I did the weekly water change with cool water. Whilst I was at work we had to get inventive and got caught out by apparently sealed bags that weren't sealed enough.

You make a good point. I've never really bothered with ice before but lost a load of young cory pandas I'd bred in the heat wave last year. This 240 litre tank has got a load of Cory's including pandas and some cw041s that I'm trying to breed and I didn't want a repetition of last year. Although these were in a loft room that got hotter than the rest of the house.

Sprouts get a bad rap from poor cooking methods. Cook them in the oven and roast them or stick them in the air fryer with some seasoning. If you really want to flavor them up, fry them in a pan with bacon.

off topic but someone had to stick up for the step child cabbage 😂

You mean you're not supposed to boil them for 4 hours like Mum does at Christmas?! 😂 . . . .and come on man, that's cheating - everything tastes good if you fry it with bacon!
