Our Story

Our Story

Reverse Respiration was invented by retired quantum physicist Mark Porzilli of Los Angeles, California.


Our highly experienced team tested and refined the concept over a six-month period. The guidelines we propose are based on evaluations conducted alongside over 250,000 field tests, with feedback gathered from users on the Aquarium Co-Op Forum, where we first introduced Reverse Respiration.

Reverse Respiration Intro to our FAQs

Reverse Respiration Intro to our FAQs

Reverse Respiration Intro to our FAQs

As more and more users reported their experiences, we refined our recommendations. To that end, we have created a short list of FAQs to address the most common questions being submitted.


                       *

 

Please Note: 

New Timing Recommendations


While these findings are not scientifically polled, consumer feedback has prompted us to reevaluate soaking times. 


We have reports of some delicate plant types being damaged by the 12-hour soak time. THIS IS EXTREMELY RARE (to date, after reaching 250,000 users, we have seen only 1:34,000 occurrences) , but as we have almost a dozen reports of this occurring, we have established new timing recommendations.


To reduce the time in seltzer required to kill algae, we have added an optional alkaline pre-soak prior to the seltzer soak to kill algae in just 2-hours vs 12-hours. 


These abbreviated times will not damage any plant types that we are aware of. 


Note for pest removal only; 2 HOURS is recommended and should prove safe for all plant types. 


                        *


NEW SOAKING TIME RECOMMENDATIONS AND ADDING AN OPTIONAL ALKALINE PRE-SOAK FOR ACCELERATED ALGICIDAL ACTION.


To abbreviate Reverse Respiration soak times for the protection of some delicate plant types, while retaining the algicidal effects of Reverse Respiration,  you may add an alkaline pre-stage to dissolve proteins in algae cells before the seltzer soak precipitates them. 


This will reduce total soak times to only 2 hours to kill algae.  A 2-hour seltzer soak must follow and is still required for the complete algicidal effect and for pest removal. 


NOTES:

If algae is not a concern, to kill pests-only, the total soak time in seltzer will be only 2 hours. 


Please adhere to timing, lighting, and enclosure recommendations set forth in the original Instructions. 


The following method should kill most forms of algae while reducing the risk to delicate plants to near 0. 


                         *


NEW INSTRUCTIONS:


Make a solution of Sodium Carbonate (Baking Powder) to raise the pH by 3 points:


Use 1/8th teaspoon (about 550G) per gallon (3.78L) of water. This should raise the pH by approximately 3 points. 


Fully submerge new plants in this solution for 2 hours. Darkness and container sealing are not required for this step. 


After 2 hours, remove the plants and THOROUGHLY rinse the plants to remove the alkaline water to prevent it from diluting the seltzer. 


Immerse the plants in the seltzer.  Adhere to lighting and submersion recommendations in the Instructions area. 


Reverse Respiration kills algae by shifting the pH. A high pH dissolves algae proteins and a low pH then precipitates the proteins, killing the algae.


The more dramatic the shift, the more potent the algicidal effect. The addition of the alkaline pre-stage increases the algae's enzymatic dissolution by a factor of 10,000. As such, this also reduces the time required in seltzer and should be safe for ALL plants. 

FAQs

Reverse Respiration Intro to our FAQs

Reverse Respiration Intro to our FAQs

What is the maximum soak time for Reverse Respiration that is safe for delicate plants?


A 5-hour soak will fatally damage most forms of algae and will eliminate all pests, parasites, and eggs. A 5-hour soak is safe for most plants.


What is the minimum soak time for Reverse Respiration for total pest elimination?


Two hours, and it is safe for all plants.


Why is Reverse Respiration patented when anyone can use it?


We always wanted Reverse Respiration to enjoy free, public access so more people would try it and realize it is infinitely superior to all other pest elimination methods. We elected to apply for (and have since been awarded) a U.S. patent for the process to protect our intellectual property.


Can I use sparkling water for Reverse Respiration?


No. Sparkling waters are not sufficiently carbonated for Reverse Respiration to take effect. Use ONLY club soda or seltzer water.


Can I add something like 'Alka Seltzer' to create carbonated water?


No. Reverse Respiration effects can only occur under pressurization. The 300% atmospheric CO2 pressure in seltzer and club soda is required for Reverse Respiration to work.


Can I turn my CO2 infusion system up fully to effect Reverse Respiration in my entire tank?


No. Reverse Respiration requires pressurized CO2. The maximum CO2 pressure possible with a CO2 system is the same as the atmospheric pressure. The 300% atmospheric CO2 pressure in seltzer and club soda is required for Reverse Respiration to work.

The Experiment

Disinfecting Aquatic Plants without Chemicals

Reverse Respiration was invented by a Quantum Physicist, a Doctor of Veterinary Medicine, a Doctor of Plant Physiology and an award-winning Aquatics Breeder. The full experiment lasted 6 months and is is published here...

Reverse Respiration is a patented, chemical-free technique that removes worms, eggs, insects, and diatoms and kills algae on aquatic plants in less than 12 hours and leaves no residue but water.

Killing algae without chemicals.

Reverse Respiration kills all parasites and bacteria through asphyxiation vs toxification and is also a Chemical-Free Algicide that cannot harm the plants...

Reverse Respiration kills most forms of algae with an extended session in darkness. No residue and no chemicals are required. As it's just CO2 and water, it cannot harm the plants.


NOTE:  To date, we have observed a 1:38,000 or approximately 0.0002% of treated plants may appear to 'melt' during Reverse Respiration and it's easy to assume the plants were damaged. Obviously, CO2 and water cannot harm your plants. If melt or apparent damage occurs, DO NOT DISCARD your plants! Unless they are necrotic, they are unharmed and will regenerate if planted. See new information (Coming Soon) on necrotic tissue and emergently grown aquatic plants before you discard any plants!

About Reverse Respiration

Our Mission

  

Reverse Respiration was an advanced scientific experiment that took place over 6 months during the peak of the pandemic. Reverse Respiration was the first of a series of scientific tests and designs to circumvent the common usage of poisons and toxins that pollute the environment and stress or kill our beloved aquatic animals. 


This website is dedicated to new, inventive ideas and solutions for old problems in fishkeeping. In the months to come, please return to read articles and proofs on dechlorinators and ammonia, emergent plants and their alleged toxicity, inexpensive aquarium chilling and oxidation techniques, and many new, inexpensive and inventive methods to solve common aquarium issues. 


Reverse Respiration, being just CO2 and water, cannot harm plants of course but it can accelerate necrosis or 'melt' and a dying plant that appears healthy, and as such, may see accelerated decay. In almost all cases, such situations are NOT fatal and the plant should still be installed. In fact, usually this is followed by accelerated growth. 


Seltzer water should NEVER be poured directly into the aquarium. It has a very low pH and a very high CO2 content and as such, is not safe for fish. Nor should a plant be in seltzer with the top sealed, as the pressure of carbonation may kill it. Fortunately, it takes just hours for the CO2 to bubble off, leaving only pure water. Please follow the instructions and you’ll be rewarded with growing, healthy plants free of disease and parasites and no residue to worry about. 


Although we have a preliminary US patent, the information is free and anyone who cares to try Reverse Respiration may do so. As it is a free, published scientific experiment and not a product or an endorsement, we can assume no responsibility or liability. By trying Reverse Respiration, you agree to these terms. However please feel free to write us with any questions and we’ll try to help if we can.
