After two week holiday – no maintenance yet
We took a two week holiday and left the fish and plants in the Fireplace Aquarium on their own recognizance. I did an 80% water change the day we set out, gave the fish a little extra food flakes, turned off the CO2 gas and otherwise left things as they were. The fish, plants, fish and snails were all fine. No casualties, and in fact everything was looking pretty good upon our return. I had expected a huge algae problem to scrape off, but that was also fine. Turns out these things are pretty robust. You can buy “slow release” holiday food but I do not recommend doing that; for a couple of weeks, if everything is healthy when you leave, things will be ok upon your return. Coming back, I gave the fish a slightly larger portion of food, did another water change, turned the CO2 back on and resumed EI fertiliser dosing.
