Agreed. I suspected nutrient deficiency from the beginning. If the NO3 comes back zero on that ATI...I’m pretty sure that’s gonna be the cause.Zero PO4 = dying corals.
I guess another misattribution to the salt, then. Didn’t watch the video though.
ICP analysis says 17,000 is normal, in Fiji. I guess that’s PPB thoughFrom Hanna instruments blog:
Chlorine analysis is extremely important for aquariums, aquaculture operations, ornamental fish ponds or any facility which maintains aquatic life. Chlorine, chloramine and their varying forms are important to track for the health of aquatic organisms.blog.hannainst.com
Chlorine in Aquatic Systems
Generally, municipal water has a relative chlorine level of 1.5 to 2.0 ppm out of the tap. Chlorine is a strong oxidant and can be lethal to most fish at level between 0.1-0.3 ppm. Although is its best to maintain levels below 0.001 to 0.003 ppm as health issues can arise in aquatic systems. Since chlorine is a great disinfectant, many beneficial bacterial strains in water or biological filter systems may be killed by its presence.
Fish may exhibit symptoms of overexposure to chlorine such as hyper activity, jumping out of the water, lateral recumbence and spasmic movements of the tail, fins or mouth. Chlorine overexposure of levels above 0.3 ppm in fish can also cause difficulties respiring, suffocation or in some cases, death. At a pH range of 6 to 7 hypochlorous acid (HOCl) is more predominant and is the most toxic form. As the water’s pH becomes greater than 7 more hypochlorite (OCl–) ions become present, and are less toxic compared to HOCl.
Chlorine can be removed from water by the use of strong aeration or activated carbon. Aging water will also work to remove chlorine as natural dissipation can occur after 24-48 hours. Sodium thiosulfate easily neutralizes chlorine, but chloramine is generally more difficult to get rid of.
Chloramine can be more difficult to remove compared to chlorine as it is less volatile. Chloramine is more toxic to fish. Water conditioners to detoxify chloramine generally use sodium hydroxymethanesulfonate which breaks apart the chloramine and converts the ammonia to ammonium, a less toxic ionized form.
Much attention is paid by aquarists to detoxify various forms of chlorine with commercial supplements known as water conditioners. Reverse osmosis/de-ionized water is also used to provide pure water samples to aquatic systems. Although these methods are used with relative success, measuring chlorine is still important to make sure that one is not harming their organisms. Sometimes RODI membranes will becomes less effective and water conditioners can expire, resulting in ineffective use. Thus regular monitoring of Chlorine in both the aquatic environment and the water source for your system is best practice.
Cl - is indeed chlorine. In tanks its usually in the form of 'Chloride' (i.e. sodium chloride) - I cant see his sodium, other levels - not interested in watching the entire video as its hard to piece all of the chemicals together. If his other 'cations' (like Na) are high - the 'chlorine' being 22000 is likely not a problem. If not - it might be a problem with RO/Chloramine - or something else. I'm sure @Randy Holmes-Farley will weigh in.So he has Chlorine in his tap water?
I think I am going to send in an ICP test of my pool water, well water, drinking water (filtered), RO water, and RODI water. Just because I am curious how this all works, and they were cheap at MACNA lol.Cl - is indeed chlorine.
