The Aquarium Vacation Checklist

Vacation is wonderful! But somewhere, the thought lingers: "Will my fish survive without me?" The idea of ​​relaxing on the beach while your aquarium at home continues to run smoothly is quite comforting. It's actually possible if you prepare your tank wisely. No stress, no fish dramas—just come home to a healthy aquarium.

Clean your aquarium 48 hours before departure with a 30-40% water change, check the filter and equipment, and choose a feeding method: don't feed for a maximum of one week, set up an autofeeder, or hire a pet sitter. Avoid holiday food blocks to prevent algae and ammonia spikes.

How to prepare your aquarium for vacation?

Essentially, it's just a maintenance service with a little extra planning. Think of a thorough cleaning, making sure all your equipment is working properly, and a feeding schedule that fits your time away. A few basics:

• Do a partial water change 48 hours in advance, siphon the bottom and check the filter.
• Choosing a feeding plan: no feeding (max. 1 week), an automatic feeder, a pet sitter, or even a live food source.
• Test whether all devices (auto feeder, lighting timer, heating) work as you want.
• For a pet sitter: leave clear instructions.
• Do not use holiday feed blocks – they often cause algae and poor water conditions.

How to make your aquarium holiday-proof step-by-step?

1. 1–2 weeks beforehand: Feed slightly more than usual (without overfeeding) so your fish have some reserves. It's advisable to feed slightly less during your vacation. If waste builds up during your vacation, you won't be able to intervene immediately.
2. 2 days before: Feed as usual but do a 30–40% water change.
   
3. One day before: Clean only the fine filter sponges. You don't want your filter to become clogged during your vacation. Leave the coarse sponges and filter media alone and only clean the fine filter wadding.
4. Choose your feeding method:
   • No food: This is fine for up to 7 days for healthy fish. (Depending on the fish species)
   • Auto feeder: set to the minimum quantity, test this beforehand.
   • Pet sitter: Pre-portioned food in bowls or pill boxes, plus clear instructions.
   • Live food: for fussy eaters, such as cichlids or puffer fish in the aquarium.
5. Ask someone to check the water level, lighting and heating occasionally.
6. On return: Observe fish behavior, check equipment, measure water parameters and perform a major water change if necessary.

Common mistakes (and quick fixes)

• Last-minute water change: do it at least two days in advance so you can still resolve any problems, and clean the filter one day beforehand. This prevents you from cleaning too much bioload at once.
• Too much food in the auto feeder: set it to the minimum and test it, it takes a bit of fiddling but it can work very well.
• No instructions for the pet sitter: divide portions beforehand and provide clear explanations. You don't want to return to an aquarium that stinks from two weeks of rotting fish food and dead fish.

Checklist

• Water change and filter check 48 hours before departure
• Set up an auto feeder or select a feeding schedule
• Labeling portions for pet sitter
• Do not use holiday blocks
• Check equipment (lighting, heating)
