A fantastic new 6ft column has been installed this week at First 4 Electricals offices. It makes a great addition to the space, and will look even better once the full compliment of fish is added. It is important to add the fish in stages to allow the tank to cycle effectively without overloading the new aquarium with too much ammonia from fish waste. The smaller first batch allows some waste to bring up the balance of beneficial bacteria in the aquarium, so that it is ready for the second batch to be added later without risking losses. So while the aquarium may look a little empty at first, it is all part of the process to help keep the fish healthy and thriving throughout the lifetime of the aquarium.
