The game give a basic detail about aquarium maintaining, however there’s more to it. Some animals and ornaments can help you maintain and improve the water quality of an aquarium, however unlike real world, not all plant in the game can do this, here’s some tips for maintaining the aquarium.
1. Filter Power
Help you maintain the water quality. Basic Filtration System, Rocks and some animal have this, it’s better to keep more rocks than just basic plants, use the live rocks instead normal rocks if possible and if possible always put the animals that have filtration power as your main animals tankmates. (example : Common Starfish with Atlantic Pollock)
2. Skimmer Power
Help you achieve higher water quality. Skimmer Machine have better filtration system than the Power Filter, only the Skimmer Machine have this. If possible use this rather than basic filter for animals that need a high water quality.
3. Nitrite Power
Help you achieve higher water quality. Nitrite Machine and just like real fish keeping, some plants have this. The machine are more efficient than the Skimmer and the basic Filter, if possible use the plant that have Nitrite Power than the normal plant for the aquarium.
4. More Fish = More Filtration
Just like real fish keeping, the more cramped the aquarium the more filtration will be needed to maintain the water quality. This is because more waste being produced by the animals in the aquariums, if you haven’t have a good filtration machine, it’s better to put less fishes in an aquarium, otherwise the animals will slowly die.
5. Bigger Tank = More Maintenance
The more big the aquarium capacity, the more heater/chiller and filtration system it need. This also work if you want to connect a water pump to more than 1 aquarium, the more tank you connect to a water pump the more machine it will need to maintain the water quality.
6. Hide Your Filtration System
The Guest dislike seeing the filtration system, always hide it with a walls otherwise you will lose some prestige point.
For early game, it’s better to use an ornament that can help maintain your aquariums rather than an ornaments just to increase your prestige. Use the prestige ornaments in late game. (for example : The Canon or Barrels)
