Tip of the Week # 3 – Waterchanges

Don’t underestimate the importance of waterchanges!

In may low demanding and more basic set-ups, weekly water changes in the range of 5% to 20% would be all that you would need to replace the consumed elements from your water as well as helping to control excesses nutrient build-up. Many people do not realize that water changes when cycling your tank can also be very important and beneficial with harming or prolonging most commonly used cycling processes.

Waterchanges when cycling a marine aquarium with at least some live rock my actually help you out down the road. This is very different from a typical fishless cycle in a freshwater aquarium. Within the nitrogen cycle that develops in your marine aquarium, you will develop bacteria that eats the proteins and turns them into ammonia.  This type of bacteria will reproduce a lot faster than the ammonia eating bacteria, so the ammonia produced can actually grow to toxic enough levels that will prolong the cycle. Typically this point occurs somewhere around 1 to 2 ppm of ammonia. This is why you have to do water changes if the ammonia reaches levels of 1 to 2 ppm or higher. The water change will help reduce the ammonia and other decaying particles from the tank helping the cycle complete faster and the water parameters become balanced quicker. Although there is some beneficial bacteria free floating in the water, it will be in such small amounts that water changes will not remove enough of them to be impactful in any way. This is why water changes when cycling with at least some live rock will help the cycle move along faster, not slow it down one bit.  This will also help to limit the potential for higher levels of nitrates before the nitrate eating bacteria has a change to develop which will reduce the risk of nitrate build up within your rock.
