I recently went to Mexico for a week long trip and had my sister tank sit for me. She's done it before and is generally pretty good about looking after things but she's no "Advanced Aquarist". I didn't want her to have to monkey about with the tank too much so I took some steps to make her life a little easier.
1. I had a 33g rubbermade tote full of RO/DI water as a top off reservoir which is good for nearly two weeks of top off water. My usual reservoir which fits under the tank is only 8 gallons, good for about 2 or 3 days.
2. I set up an automatic fish feeder to feed the fish once in the morning and once at night. By the way, what a great little device! I got the Eheim one. I like it so much I use it almost full time now. It plops food in in the morning only though as I still like to hand feed (my fish mush and PE mysis) for the evening feed.
3. Lastly I decided to modify the skimmer to collect a week or mores worth of skimmate. In the past I just turned the skimmer off. However, this time around I wanted to keep it on but I didn't want my sister to have to empty the skimmer cup every few days or so. The cup does fill up pretty quick. Well, it doesn't actually fill up, but it fills enough (about half way) to a point where the foam itself has no room and starts to bubble over. Anyway, here's what I came up with.
I used one of these elbows and simply chopped off one end like so.
I then drilled a hole into the base of the skimmer's collection cup the size of the chopped off end, like so.
I then silliconed the elbow into the collection cup.
Then I stuck an appropriate sized hoze into the nozzel.
And voila!
At some point I'm going to put a valve inline there. This has worked out well and I have not touched the skimmate collection since before I left. I do dump some fresh water into the cup to rinse it a bit though. I will probably be using this full time even though it was only meant to be temporary.
Also, I think I can use a slightly smaller bottle, like a 2 litre soda bottle would be fine, instead of that gallon monster I have on there now
