A worrying time for aquarists is when there is a power cut. Aquariums rely on electricity to keep everything alive and healthy. Here are some useful tips for when a power cut occurs:

  • Remove and drain all filters (internal and external). Clean filter sponges in a small bucket of aquarium water if very clogged. Place sponges in an airtight container or a sealable bag with little to no water so they remain damp. This is important! Bacterial colonies living in the sponges need constant flowing water to survive. If they are left in water, they will drown. In a damp environment, they will continue to breath and not dry out.
  • Water is effective at maintaining heat, so the temperature of the aquarium will not drop too suddenly. If the power cut prolongs for several hours, it may need to be warmed up. In houses with a gas supplied hob, you can warm up water and pour into plastic bottles to then float on the aquarium. It is important not to pour hot water directly into the aquarium! This could lead to isolated hot spots where fish could become burnt, and the introduced water can affect water chemistry.
  • With no water movement, the water’s surface will prevent any gaseous exchange. This means no oxygen coming in, and no carbon dioxide dissipating from the water. To manually provide gaseous exchange, use a jug to collect and pour aquarium water on to itself. This will break the surface and allow these gases to exchange. Stocking density will determine how often this needs doing. If you notice the fish acting sluggish or gasping at the surface, this is a sign the oxygen levels are low.
  • Battery powered air pumps are an inexpensive product to keep in case of a power cut. They will allow oxygen to continue being present in the water by breaking the surface.  For the keen hobbyist, back up power systems are also an option. These UPS power banks (uninterrupted power supply) can provide power to an aquarium filter for an extended period of time. Most are programmed so will only switch to battery power when a power cut occurs. It would not be recommended to power the heater from this source as the higher wattage would decrease battery power time.

Koi Water Barn and NT Labs have a long history of working together, we feel that the products in the Koi Care range offer our customers a quality product at a realistic price. This is backed up by extensive research and development that is carried out at the NT Labs HQ located in Kent. They are not far away from our shop at Coolings (Knockholt, near Sevenoaks), this is an added bonus for our customers as they are buying from a local UK based company.

We have been working closely with NT labs for many years now. We stock their Pond range and test kits, we strongly believe they are the best liquid test kits on the market, we use them in-store and have sold many over the years. Last year we have began stocking more of their fantastic ranges including their Pro-f food range and Aquarium range of water treatments.

“I Just wanted to say thank you for the help with bacterial issues I had in my pond. I can happily say that the mouth rot of one fish and the fin rot of two others has cleared up to near perfection now. I have been really impressed with the service from your technical team. I have already recommended online that people ask NT Labs about their products and recommended usage.”

Your Probiotic food is absolutely brilliant! I bought twenty one 1 year old Japanese Koi via a fish farm in Ogata, Japan about 3 years ago. I’ve been feeding them on Probiotic and Probiotic Growth in the summer months. Some of are now 2ft in length and of superior quality. It’s not cheap, but you get what you pay for.

I have used many products for the eradication of aiptasia over the last 15 years. Often with poor results. After purchasing the Anti-Aiptasia, I was astonished with the results! Absolutely fantastic and not like the competitors which normally contains some form of hydroxide. I would highly recommend NT Labs Anti-Aiptasia. This is arguably the best in the market!

I work at a pet store in Durban (South Africa) and have had the best results with my salt water aquariums that I have EVER seen. I have been in the industry for about 10 years now and seriously recommend the products supplied by NT Labs. All our customers that have used anti-aiptasia swear by this product and have said that it over rules every other product out there. Highly recommended.

"I called your offices for support and was put in touch with one of your Aquatic Biologists. He has been incredibly helpful... Without your help, my fish would be suffering and I might have had to stop keeping Koi. I cannot recommend your products, or staff, enough."
