Why didn't I think of this sooner. No need to have a real person helping out. lol
Here are a few examples that I asked it today, in order of increasing difficulty (IMO):
1. Describe the importance of alkalinity and calcium in a coral reef aquarium.
ChatGPT reply:
Alkalinity and calcium are important in a coral reef aquarium because they play crucial roles in the growth and health of coral and other marine organisms. Alkalinity, measured in terms of carbonate hardness (KH), helps to maintain a stable pH level in the aquarium water, which is necessary for the survival of coral and other marine organisms. Calcium, on the other hand, is a vital component of coral skeletons and is necessary for their growth and maintenance. Without adequate levels of calcium, coral will not be able to build or maintain their skeletons, which can lead to slowed growth or even death. It's important for the aquarist to test and maintain proper levels of Alkalinity and Calcium to ensure a healthy and thriving coral reef ecosystem in the aquarium.
Randy rating: 60%. It fails to explain that alkalinity does anything other than stabilize pH, but does a decent job with calcium. Answered immediately.
2. Describe the effects of phosphate in a coral reef aquarium.
ChatGPT reply:
Phosphate is a nutrient that can be found in many types of aquarium water, including coral reef aquariums. In small amounts, phosphate can be beneficial to coral reef aquariums as it is used by many types of coral and other marine organisms as a growth substrate. However, in high concentrations, phosphate can lead to the excessive growth of unwanted algae and other organisms, which can outcompete and harm the coral and other desired organisms in the aquarium. High levels of phosphate can also lead to decreased water clarity, and can make it more difficult to maintain proper water chemistry. To maintain a healthy coral reef aquarium, it is important to monitor phosphate levels and keep them within a safe range. This can be done through regular water testing and by using phosphate-removing products, such as phosphate-adsorbing media or liquid phosphate-removing solutions.
Randy Rating; 80%. Very good, IMO. It might have just been traffic, but it thought about this one longer.
3. Why is strontium incorporated into coral skeletons?
ChatGPT reply:
Strontium is incorporated into coral skeletons because it is a chemical element that is present in seawater and can substitute for calcium in the formation of the coral's exoskeleton. Strontium isotopes can also be used as a tracer to study the coral's growth and environment.
Randy Rating: 95%. It might have added that strontium looks chemically like calcium .
4. Why does a conductivity measurement need to be corrected for temperature to allow determination of seawater salinity?
ChatGPT reply:
A conductivity measurement needs to be corrected for temperature to allow determination of seawater salinity because the conductivity of seawater changes with temperature. This is because the concentration of dissolved ions in seawater changes as the temperature changes, which affects the conductivity of the water. By correcting the conductivity measurement for temperature, the effects of temperature on the conductivity of the water can be eliminated, allowing for an accurate measurement of the salinity of the seawater.
Randy Rating: 5%, total fail. The conductivity of seawater does not change with temperature due to the number of ions changing, but rather to the change in the mobility of each individual ion.
5. Is a refractometer or a conductivity meter a better way to measure seawater salinity?
ChatGPT reply:
A refractometer is typically considered a more accurate way to measure seawater salinity than a conductivity meter. This is because a refractometer measures the actual salt content of a sample, while a conductivity meter measures the electrical conductivity of the water, which can be affected by other factors in addition to the salt content. However, conductivity meters are generally more convenient and easier to use in the field, and also cheaper. So it depends on your purpose and situation.
Randy Rating: 10%. Fail. The answer is partly opinion, which it cannot fail, but the description that a refractometer measures salt directly is ridiculous.
6. Is silicate a limiting nutrient for dinoflagellates in a coral reef aquarium?
ChatGPT reply:
Silicate is not typically considered a limiting nutrient for dinoflagellates in coral reef aquariums. Dinoflagellates, like most marine phytoplankton, require a balance of macronutrients (such as nitrate and phosphate) and micronutrients (such as iron and manganese) in order to grow and reproduce. While silicate can be present in seawater, it is not typically considered a limiting nutrient for dinoflagellates. However, silicate can be used as a nutrient source by diatoms, another type of phytoplankton, which can compete with dinoflagellates for resources and lead to changes in the community structure.
Randy Rating: 99%. Very good. I'd remove the word "typically" as it implies some scenarios where it may not be true, but otherwise an excellent answer.

Convincing nonsense. The correct answer is that there's no clear connection whatsoever between reef tank iodine levels and dinos, but instead it says, sure there is - iodine dropping too low drives outbreaks, and here's what you should do about it. YIKES!
