Based on 37 years of professional aquarium maintenance, experience, and research.
Unlike many aquatic websites, much of our research is outside the aquarium industry/hobby, so as to not rely on common anecdotal assumptions (such as Redox). We also use aquaculture, horticulture, medical, lighting industry, and university research papers to pair with our experience to compile many of our articles.
Resources to keep your aquatic pets, (fish and more), happy and healthy!
Please scroll down to the navigation list and scroll more for descriptions of each article.
• Please note, some of the articles both here and in Aquarium & Pond Answers are more basic (such as Goldfish Basics), however others such as Aquarium Lighting are intentionally more in-depth and need to be read in full (often multiple times) to fully understand.

Aquarium Answers Articles
(In order of writing/posting)
Aquarium Chemistry- Calcium, Electrolytes, KH, GH, pH, and Magnesium Many aquarists overlook the need for all aspects of aquarium chemistry with the effect of a proper KH (Carbonate hardness). This is especially important with livebearers, goldfish, African cichlids, brackish and many other freshwater fish. The production of Nitrates (nitric acid) will slowly reduce your pH, but a proper KH will keep a more stable pH.
As well, a correct understanding of what GH test does and does not show as to providing necessary positive mineral ions/electrolytes.
Finally, there is much misunderstanding of Calcium and its importance to ALL fish from Discus to marine. This article explains this and also provides outside references as well. Also, information about the set-up and maintenance of an Amazon River/SE Asia low pH aquarium.

Aquarium Disease Prevention Proven steps for a healthy aquarium. With many aquarium over the years, steps have been found to help with sick fish before there's really a problem. Prevention has been the best remedy for aquarium health.
Aquarium Lighting- Kelvin, Nanometers, PAR, and More When choosing lighting for an aquarium, there's much more to consider than watts per gallon. The 2-4 watts per gallon for a Nano reef or freshwater plant aquarium, less for fish, more for hard coral. It's a start, but is very general. There are other factors effecting lighting for your aquarium than just watt output. For example: You cannot compare the output of a 150 watt Metal Halide to a 150 watt outdoor floodlight. Sometimes it comes down to comparing apples to oranges.
This article will explain i detail the important parameters and aspects of lighting. This is also my most updated article do to the amount of new information and research constantly available in this field, including the new SHO, T-2, LED lamps and more!

The Redox Potential A Redox Potential in the -200-400 mV range for human studies has been shown to have the same affect as anti-oxidant preparations such as Vitamin C (and many others). This article shows that the health of aquarium fish can be maintained proper electrolytes and by a UV Sterilizer, not just by the killing of potential disease pathogens, but by the maintenance of a proper Redox Potential. This is an article every serious aquarist SHOULD READ!
Fish Nutrition There is a lot of confusion about what constitutes fish nutrition and what ingredients are needed for proper fish nutrition, growth and health. The aquarist needs to understand there are similarities and differences between fish and other animals. For example: Fish get most of their energy needs from fat, but in humans carbohydrates are a better source. Another point is amino acids (the building blocks of proteins). Almost all animals have different amino acid needs. For example: Cats need Taurine in there diet or they can suffer heart problems

Spirulina Algae The aquatic health benefits for Tropical, Marine and Goldfish- Spirulina a planktonic blue-green algae found in warm water alkaline volcanic lakes rich in raw protein and seven major vitamins: A1, B1, B2, B6, B12 (one of the best natural sources for B12), C and E. It naturally contains beta-carotene, color enhancing pigments, and whole range of minerals. In addition, Spirulina has a 62% amino acid content and contains all essential fatty acids and eight amino acids required for complete nutrition.
Aquarium Ich- Ichthyophthirius multifilis and Cryptocaryon irritans This article deals with a common disease (protozoan infection) in freshwater and saltwater. Also, the treatment, identification, and life cycle. The scientific name for freshwater ich is “Ichthyophthirius multifilis”. The marine protozoan causing Ich is “Cryptocaryon irritans”. Both organisms cause whitish spots, called “cysts”, to appear on the bodies and fins of the infested fishes.
Included in this article are: Identification, Life Cycle, Prevention, and Treatments.

As noted near the beginning of this page, some of the articles both here and in Aquarium & Pond Answers are of a more basic nature (such as Goldfish Basics). However, others such as Aquarium Lighting or intentionally more in depth and need to be read in full (often multiple times) to fully understand rather than just snips.
A little background: When Carl first started writing these articles for the internet (something clients asked for years), Carl made them VERY basic. His early feedback was rather harsh as many said it was "nothing special". Then some who knew Carl better said, although they were still better than many in content due to less anecdotal information, they did not come close to the delivering the information they knew Carl could and his constant research should be reflected. Many experts in SEO told me similar as well.
So now, although some of the articles are still more basic and not all that unique, many however will have well researched information people will not find elsewhere in one location and this information is only best understood when read in full.
Carl will make his point as to why he feel it is so important these articles be read in full and not in snips which can result in anecdotal or poor information dissemination.
"In the 1980s Carl was mentored by an Endocrinologist (MD) whom was also an avid fish keeper (mostly marine). He helped Carl much understand the ins and outs of medications, and one time gave him an in-depth medical article, which he though had useful information, which could be applied to fish as well. Much of the information was not readily easy to understand for Carl, so he skipped over many sections and gleaned the points he wanted.
Later, Carl was making some points to the doctor and he stopped Carl and said he was incorrect and if he had read the article in full, to which he replied, 'no'. He then said there's no way Carl could understand this article without reading it in full and applying ALL the information contained there in".
The point is, often it is easy and unfortunately ALL too common in this hobby to read just what we want, and many web sites (such as about.com) are good at satisfying this basically lazy desire (of which I too have been guilty of), however this often leads to poor understandings of the subject or worse.
Another point is Carl dose not like to make diagnostic charts or similar such as lighting charts for aquariums as there are too many variables making such charts or comparisons often inaccurate (as the mentor of mine noted above also pointed out to me).
Finally, a point for those who stick to the closely held anecdotal beliefs, which so badly permeate the aquarium keeping hobby rather than read researched articles and CITED REFERENCES such as these here or at Aquarium/Pond Answers, is best summed up by another Mentor of Carl's, (Reggie) at an aquarium supply wholesaler, which finished his business career there (after most of his decades of business in different industries specializing in making poorly managed businesses successful again) told Carl this:
"I have never seen a more dishonest and back stabbing business than the Aquarium industry".
His point was about how often he found persons in this business/hobby would outright lie or simply ignore new/good science to either make a sale or not give up their tightly held anecdotal beliefs.
Often these persons will make personal attacks on people such as Carl when they cannot refute his research and experience. Or they will make red herring arguments that an article is not peer reviewed so therefore it is not credible.
Sorry, but if a half a dozen "peers" sit around a table giving a thumbs up, because when they look out over the ocean and see that there is a clear end, this proves the world flat. Unfortunately this does not make it true.
Case in point is Carl's Aquarium Redox Article, where it has gotten a lot of positive reviews from outside the aquarium industry, but not within as many from so-called peers. Frankly those in research outside this often closed minded hobby have much more funding and cannot earn a living if they were attempting to please the status quo in the aquarium hobby/industry. This same problem is common when it comes to aquarium lighting where many refuse to look outside the hobby into research and practical use and instead will make these same red herring arguments in a vain attempt to refute his information
