" The Redox Potential in Aquariums and Ponds and how it relates to proper aquatic health" Filtration As well, dirty fish such as goldfish normally do much better in ponds where there is natural sunlight and good water flow, this is proven to be large contributor to long term goldfish health in aquariums.įor more about the Redox Potential, please read this article: The result can be "Yellow Water" which in itself is not necessarily a problem, but can be an indicator of unstable KH/pH and rising nitrate.Īnother parameter of chemistry (not often considered) for long term health and growth is maintaining a Balanced Redox Potential, although not considered essential, newer evidence seems to refute this line of thought. Please Read this article for more (in particular the FAQ Section):Įxcess organics, which is common to goldfish aquariums due to their higher impact on bio load when compared to many other fish, can often lead to higher nitrates and lower KH.
Keep in mind that excess organic wastes can also affect your pH/KH, so even if your ammonia and nitrites are near 0, a problematic nitrate level can result in problems with pH and KH stability. Unique AAP Wonder Shell Aquarium Mineral Ion Replenishing BlockĪ KH of 100 ppm or more is useful for pH stability and providing the higher carbonate water goldfish generally prefer.įor more about the importance KH, GH, electrolytes and Calcium play in fish heath- especially goldfish health, see this article:įor the chemistry as it pertains to organic waste and the water parameters there of for optimum health of goldfish, I recommend keeping an ammonia/nitrites level of. The use of Mineral Blocks such as Wonder Shells is strongly advised for goldfish for this reason). However the positive ions of these minerals will become exhausted even when your test kit shows an adequate GH, especially when water changes do not keep up with replenishment of these mineral ions.
#Starting a goldfish aquarium plus#
Generally providing a GH of 150 ppm plus (200-500 GH is best) will provide these minerals assuming very regular water changes and replenishment of these essential mineral ions. If a bowl is all you have or can afford, a betta, or even a paradise fish or guppy is a better choice.Īlthough goldfish are not very particular about water conditions, they still do better at a ph of 7.0 to 7.8 (although I have successfully kept goldfish at lower & higher pH, so I would not worry too much about the pH number, rather pH stability).Ī high mineral content is a must, especially important for Goldfish is a constant supply of positive calcium and magnesium ions. New or experienced aquarist a new aquarist needs to start with a much less crowded aquarium.Īs for goldfish in bowls, this is not an appropriate place to house any carp, which is the family to which goldfish belong. Goldfish need a kH of at least 80 ppm, but over 160 ppm is better. Well maintained water chemistry (including kH and Redox). Maintenance schedule that includes regular efficient water changes. These tall aquariums resulted in generally lesser fish health and longevity.įiltration- a properly filtered aquarium (good bio filtration, good mechanical filtration, and good circulation) with multiple filters is important. I have observed many tall narrow aquariums over the years of my maintenance service where the filtration and other factors were equal to comparable sized and stocked rectangular aquariums. The amount of surface area relative to the gallons of water the aquarium holds. Here are a few more factors in determining the amount of goldfish you keep in your aquarium:
In a well maintained aquarium of appropriate size (I recommend 8-10 gallons to start with and 20 + per goldfish for long term health and growth), 15+ years is not uncommon. Goldfish can sometimes live 20 years, but this is usually in Ponds.
Shubunkins make a better choice than common or comet Goldfish, as they receive better treatment in shipping and are not as "over bred" (and of course Ryukins and Orandas are great choices when it comes to their beauty). Many goldfish are imported in very cold water, in crowded conditions, making them very susceptible to disease (especially ich). First let me preface this article to point out that this is extremely basic information and that I recommend following the "further resources" provided within this article for much more in depth information, as well as these articles/resources:
