The bubbles ain't my thing. I'm a drip kinda guy. If the high temps are a temporary thing (if you are in northern Europe, they are!) Keep on with the frozen bottles till the weather breaks.
I did see somewhere a cheap reservoir cooler that's was an old fridge with a coiled up hose pipe in it ,with a pump running it around the reservoir.
Check out other hydro systems, you can make some yourself if cash flow is a problem (you have a fat tv to replace after all).
Oh, and I'm glad there was no kids or animals that were involved in your break up, it may not seem it, but it could've been a lot worse.
Here's a tip, make sure your next woman smokes more than you, actually, witchy is single.
