I really liked this video, You explained the topic really well and, I just love that you didn't add music to it, really good video mate. just subscribed.
Hey John, I just watched through the rest of your videos related to the crash. In a previous episode you talk about the crash being initially caused by using tap water whereas here in this video you seem to be blaming overstocking and lack of bacteria population. Did you get an ICP analysis done on your tank at any point after the crash? I ask because I tend to think you may have a heavy metal issue that caused the tank to crash either via the tap water or a magnet/metal corrosion. An ICP now may even help to confirm whether you continue to have a heavy metal issue (if this was the cause as I suspect). I highly recommend getting an ICP done asap, especially if you begin to add new corals and they aren’t doing well. If heavy metal(s) are found, you need to take apart and inspect every pump, wave maker and anything with a magnet to look for rust/corrosion. Best of luck getting this tank back up to full steam and better than it ever was!
You do have a good point! I was for the last two years before March of last year using tap water instead of rodi water, and now I'm wondering if an icp test would have caught the issue. That's a great idea! I will go ahead and get an ICP test done on my tank water, and get a better idea of what is going on with my saltwater aquarium. I really appreciate your help. Thanks
I was with you until the end, but you have a pretty large error in your final bowl demonstration around 3:46...what do you mean caused your tank to crash? Do you mean your ammonia production outpaced your denitryfying bacterias capacity to process it to NO3, or are you suggesting you reached such high levels of NO3 that your cnidarians were dying? You are correct that ammonia is ultimately converted to NO3 by denitryfying bacteria, and you need a robust bacteria population to handle the ammonia burden on the tank, so if your tank isnt fully cycled, or if you add too many fish too quickly, it will outpace the bacteria temporarily until they catch up. This usually results in fish death, as they are intolerant of ammonia. But this doesn't take long to develop once the tank is cycled for a few weeks, it becomes pretty resilient to even very large additions pretty quickly, though you should monitor anmonia during the process and be prepared to do large water changes in an emergency the first few days after the additions. However if your suggestion was that you were building NO3 too quickly because you lacked sufficient bacterial colonies, you are conflating issues. There are 2 types of this bacteria, aerobic and anaerobic. Aerobic are the biggest presence and responsible for converting ammonia to NO3. Anaerobic actually break NO3 down, but they are in such small quantities and only establish under certain circumstances they are rarely a significant factor. They develop deep inside of porous rock, and in deep sand beds, which can develop dangerous hydrogen sulfide if they go anoxic. Anyways your anaerobic bacteria is never going to be sufficient to handle a large fish bioload and process NO3, you either have to do carbon dosing to artificially grow this anaerobic bacteria and export it out of your skimmer, or you have to export through macro/micro algae growth in a refugium. There are no other significant means of NO3 removal, even purigen etc.
My understanding is the tank crash was caused by lack of bacteria to convert ammonia to nitrite (or possibly lack of bacteria that convert nitrite to nitrate). It’s a little confusing because he starts the video off talking about reducing high nitrates in his aquarium. But he is talking about his tank in its current condition (i.e. post crash) where his bacteria population has caught up and converted all previous ammonia and nitrite into nitrate.

Im glad you like the video and I hope to upload better quality videos soon.

Love that Pom bro
He has that longer nose that is more oldschool which I like
Thanks he's my new baby. I recently got him after I had to make the sad decision to put my last Pomeranian Cotton to sleep. I really miss him.
