Performing Water Changes

Water Changes reduce nitrates, increase oxygen and mineral value

Water changes must be performed frequently to keep oxygen levels up and nitrates down in our goldfish house. We’ve learned that beneficial bacteria are responsible for the nitrogen cycle. Without these friendly bugs, goldfish would be poisoned by their own waste. Keeping fish safe in captivity would be a challenge if not impossible without this miracle of nature

Without the nitrogen cycle, life would not exist as we know it

Nitrates are the third and final conversion in the cycle; tolerated by goldfish at low levels. This toxin can only be removed by means of a partial water change. If the environment in your goldfish house cannot support beneficial bacteria, then it will support harmful bacteria. If bad bugs flourish in your tank or pond, your goldfish won’t. It’s that simple

Exchange less water more often to keep nitrates at consistent levels

Water changes

Another reason to perform frequent water changes; goldfish emit a growth hormone dangerous at high levels. Goldfish in overstocked tanks are at risk of being poisoned by these hormones which may stunt growth. These same hormones cause cancer, heart disease and even death

Add plants to your set up. Plants feed on nitrates keeping levels at bay. There is one plant that forms naturally in the right conditions with no maintenance, and that’s algae

Fish are at risk of ammonia and or nitrite poisoning if the cycle has not completed

Changing goldfish water

If your tank has not cycled, perform daily water changes between 20% to 30% (depending on stocking levels) for the next 8 to 10  weeks. Use water treatment (enough for entire tank size) that eliminates ammonia, nitrite, chlorine and chloramines

Refer to Step 5: Water Treatment: to determine recommended dosages required for making conversions

Never perform a 100% water change. Along with the bad bacteria and toxins, you’ll be throwing out water that provides nourishment for good bacteria also

If your tank has cycled perform bi weekly water changes of 10% to 20% depending on stocking levels. Eliminate chlorine or convert chloramines using water treatment if present

An overstocked tank requires increased amounts of partial water changes

Test fish water before every water change; adjust water changes accordingly. The comfort zone is 20 to 40 ppm with the lower end of the scale being preferred; a buffering zone in case of a spike

Here are some tips to keep water changes easier

  1. Make sure water buckets have strong and secure handles 
  2. Keep the buckets light so they’re easy to carry; don’t over fill
  3. Take your time. Don’t rush through bailing water; slow and steady
  4. Keep a towel beneath buckets while removing or adding water 
  5. Keep filters and pumps in fish water at all times
  6. Never use detergents or cleaning agents on goldfish house or equipment
  7. Work water over to remove supersaturated gases from tap water
  8. Never add water treatment or any other substances directly to goldfish tank
  9. Keep a watchful eye on running water from a faucet unattended
  • How to perform proper water changes

Match the amount or percentage of old tank water you are going to remove with your freshwatersource

Prepare fresh water by adding treatments and eliminating super saturated gases

Vacuum waste from gravel, beneath pumps and decorations

Replace old tank water with freshwater gradually in order to prevent nitrate shock. Take your time by removing and replacing 5% every half hour in a cycled fish house. This added effort will help your fish to acclimate to the change of nitrates and temperature of the fresh water, reducing the risk of shock

Partial water changes accomplish much more than assuring the continued production of friendly bio bugs. Partial water changes allow the goldfish to remain in the safety of their tank or pond. There may be some stress involved with the event, however, much less than being caught and temporarily relocated

Oop Boost with every water change to improve oxygen levels and to eliminate chlorine (does not remove chloramines)
