Great video, and interesting results. I've been waiting for these results for a long time. An interesting anecdote from my own experience, I give my dry rock an acid bath in plain old vinegar. I haven't ever done a detailed test like this episode, but I can tell you that soaking the rock in vinegar produces a dirty thick foam, similar to what we saw in the video when your team placed the rock in the water/acid mixture. Household vinegar is 5% acetic acid, and the solution you mention (1:20 HCl to water) is about 5% as well. Because vinegar is already diluted, it's much safer. While vinegar costs more at a dollar per gallon, I think it's a solid alternative to more acidic and corrosive HCl-based acids. Great video, and thanks again for the series.

Great Video and thanks for taking the time to do this. I also did the Acid and bleach to my rocks about 1 1/2 years ago but it was not to help with the cycling of the tank. I did it because I know I am going to have a heavy stocked tank. I wanted to start off with the Phosphates as low as possible to help to reduce my monthly expense on phosphate removers. I know have about 30 fish in a 530 gallon tank and my last test using a Hanna checker showed my phosphates at .31ppm. I know recommend this to all of my friends. I say this is like building a house. If you have a bad foundation you will always have issues. This is only smart way to start the tank. Took me about 4 months to get the rocks ready but the tank looks great now.

Thank you guys for going through all that hazardous testing to bring the community these results! I love how informative this series is. I feel that it is very important to note however that the acid and bleach bath clips showing that guy wearing a respirator are kind of misleading (unintentionally). No respirator in the world is going to protect you from dangerous fumes if it can't make a proper seal with your face, and you can't get a proper seal when you have a full beard. Just something to point out to any men in particular who might be wanting to try these methods. If you're going to wear PPE, make sure you have it on correctly, and be safe!

@Philsta007 2 жыл бұрын

The safety stuff is completely over the top anyway. People use bleach to clean their homes all the time (including in small confided areas like laundry, bathrooms and toilets) and you don't see housewives wearing a full respirator. Hydrochloric acid is also not nearly as dangerous as this would have you believe, especially at a 10:1 dilution.

Thanks for doing this video! I followed your advice and soaked Pukani Rock in 1:10 Bleach water for a week. I then dried them out in the sun for a day and soaked them in RODI with dechlorinator for 2 days. Originally I was planning to just start cycling the rocks from here but after a week in saltwater I decided to go a step further. I did a 50:50 vinegar bath using Heinz cleaning vinegar and saltwater for 30 minutes. I got this idea from reading the video comments. Before removing them from the vinegar bath I did do some light scrubbing. The results were very surprising and had removed almost all the dark stuff from the rock. I rinsed/dipped all the rocks in saltwater before placing them back into the container. Since using vinegar is a much safer option than acid, maybe BRS can do a follow up video. Would be really nice to see how vinegar compares to acid. Thanks again BRS! Note - All this was done outside using a 32 gallon Brute Trash can and powerhead. I also wonder if using vinegar as the last step in the process helped to make it more effective.

@justindancinghawk3885 Жыл бұрын

I'd be very interested to see the results with the vinegar! Here's a step further. . ..what about dumping in some baking soda!?!?!! That will cause a quick & rather volatile, yet *SAFE* ( I'D RECOMMEND THIS BE DONE IN AN OUTDOOR SITUATION! ) reaction that I think would almost certainly bring positive results! come to think of it, I think I'll try it & report my results via my FB page ! Perhaps I'll start a new page specifically for my reefing experiences! Watch for " Tranquility Bay" on various social media!

Very good video guys. It seems the acid/bleach method is the way to go, it gives you the exact amount of PO4 in your water that'd you want for an SPS tank and removes as much of the "bad" stuff you don't want in your tank. But because I'm lazy, I'll still just do the salt water/heater/powerhead curing method and wait. :)

From a cleaning perspective, I would recommend doing the bleach first. If the organics are still adhering to the rock, you will likely not get as good of a removal step with the acid. As someone else mentioned....always add acid to water and not the other way around :) (same for mixing basic solutions as well)

@joshuac673 5 жыл бұрын

I own a pressure washing business and this is how our cleaning process works for organics on roofs which is a rock in a sense including metal roofing. 3-5% bleach concetration to kill molds mildews and algae. so 2 gallons to 20 gallons isnt going to cut it....3 being the minimum for your average roof but for dirty shingle roofs with heavy organics and metal 5% and usually takes care of the organics in about 5-10 minutes after application. Also Im not sure if you can add soap to this mix for it to be safe for later use but soap reduces surface tension bc its a surfactant so add a little to the bleach mix and it can get into the cracks a little better.

For those who want to experiment with acid, I'd recommend "glacial acidic acid" as an alternative to muriatic acid, though one must still be careful: always slowly add acid to water and not water to acid when mixing the working solution. "Stop bath," a chemical used in photo development, is a dilute form of the glacial acidic acid and is safer to use. The Kodak brand has a color indicator that might stain the coral, so I'd recommend other brands unless you're going to follow the acid bath with a bleach bath (which gave the best results in the test). An acid bath is also useful in fresh water aquariums: an acid bath of a rock with unknown lime content can be neutralized or identified by the chemical reaction. Such identification and/or treatment would be desirable for a tank in which one wants to keep soft and acid water from changing pH upwards. But it is bleach that does the ultimate job on all biological material by attaching an oxygen molecule to all bio-molecules, thereby "rusting" and killing all potential problems. And, PS, great job guys, in testing aspects of this hobby and keeping things out of the realm of rumor and guess work.

Just a FYI to BRS: great job with your analysis and data presentation (coming from a marine biologist), but when you plot your data you should be using straight lines on your figures.

@Kamel419 6 жыл бұрын

I disagree, there is absolutely no reason the curved trendlines are an invalid choice. The real points are well labeled, and the actual trend likely followed the curved visual more closely than straight lines. Further, it is up to the person presenting the data to choose how best to represent it using their subject matter expertise to infer what visualization most likely represents actual. A lot goes in to data science and visualization. You can't merely follow rigid rules like this otherwise there would be no purpose or value in the field - everyone would just follow the rules and that would be that.

We haven't revisited this test, however letting the rock completely dry out and then doing a bleach cure would probably yield the fastest results in your situation. Of course, be sure to take the proper safety precautions when using bleach. If you're willing to give it some time, letting the rock dry out and then performing a natural cure is the easiest and lowest stress way to go in most cases.

Was the water changed before each weekly test? If so, and even after several weeks there is still a constant level of phosphate, then that would mean phosphates are leaching off the rocks, just at a steady rate (?). If the water is not changed, then I guess phosphates probably are no longer leaching off. But if the water was not changed out, then how were phosphate levels lowered after peaking?
