Yo man just found this site and thank fk i did, Have you tried the new coco boost stuff that is on the market. It cost a lot of money and is it really woth it? List of details of the national reporting systems to communicate adverse reactions (side effects) for use in section 4.8

Probably thecheapest and still the best vessel you can use. If you. canfind one of those four- liter versions, that iseven better. There are several factors that make the soda bottle a. First off, it is designed to hold asolution of water with dissolved CO2. The pressure that builds up. I would venture to say. The capand how to attach the tubing is another issue that. Most of these caps from. Polyethylene doesnot readily bond with most glue. So gluing the tubing in placeis not desirable. Leaks will occur, especially atthe. Furthermore, since we're dealing with gasses, the sealmust be airtight. The best all aroundsolution is some. Some type ofbulkhead. Gas Delivery (tubing)Gettingthe gas to the tank water is the next. Tubing should be selected based upon several. One ispressure retention, or the ability of tubing to. As tubing is put under. Also the tubing will need to be inert; meaning not. CO2 gas internally or the air or water. This pretty much eliminates standard airline. Another consideration. A goodcandidate for this application is silicon. It does not react with CO2 as quickly, has good pressureretention characteristics and is veryflexible. There is. also special tubing designed specifically for carrying CO2 gas, and I would encourage spending the few. But silicon tubing willlast for several years, and is in keeping with the cost savings. DIYimplies. Itis also important that water isnot allowed to. This problem. iseasily remedied with the use of a check valve. Many. check valves are available commercially. Several factors should. I would avoid choosing one. The caustic nature of CO2 gas, the high water vapor content of the. Therefore it is importantto. CO2 applications. In addition,for the. I recommend avoiding the useof any. In pressurized tank. So the use. of metalcomponents is common in thesesystems. The. same should not beassumed on a yeast based DIYsystem. Getting the gas dissolved in the water. Thisis a topic that has received much attention onmessage boards, mailing list servers, andnewsgroups over. And Ithink rightfully so! Many methodshave been described on what the best way to dissolve the CO2 gas into the tank water. This is. the critical point in determiningthe effectiveness of a. DIY system and the reason why many feel thattheir. DIY systems was a bad one. Since the amount of CO2 available in a yeast system is limitedby biological production, it is important to get most,if. CO2 produced dissolved into. Skimp here, and you have wasted yourtime, not to. CO2 gas. Thesimplest, and least effective, method is torun the tube into the tank and simply letthe gas bubble. I do not. recommend this method at all. Since most of the CO2 gas simply rises to the surface andis lost. Next,many have suggested placing this tube at theinlet of a canister filter and allowing theimpeller to. While it is effective in dissolvingthe gas, I do not like this method either, for tworeasons. First, the CO2 bubbles can. Second, some of the componentsin the. CO2 gas and carbonic acids present. Abetter but slower method is the use of. CO2 bell. Simply put. CO2 is allowed to fill up inside. These arealso. very simple toconstruct. Many have been constructedfrom cutting off the tops of one- litersoda bottles. I would recommend using amaterial or object that is. Anothermethod is a diffuser. Two. versions of diffusers exist. One is device that increases the. Usually bypresenting the bubble with a long spiral courseit has to. In the image to the right isone example of this type. Econo Aqualine. 50. Aqua. Botanic, andothers. The manufacturer. The reactor issufficient for an. Gallons. This unit is mountedon. This is a. devicethat increases the surface area of the CO2 gas by reducing thesize of the. Thisis a proven method and can be. CO2 gas to be dissolved. This plate has. thousands of poreswhich the gas passes through, and once it. This all glass unit is. Japan. Other manufacturersmake similar products. The onlydrawback of this method. Other than that singular. The drawbacks. of bothversions is that their mechanical sophisticationdo not allow themselves tobe easily homemade, and. There are manycommercially available choices. The best method,in my opinion, is the use of a forced. A forcedreactor is. The previous methods are. In other words if circulation of the. By forcing mass quantities of water tomeet the gas, via a pump, and mixing itthouroughy the. In general a forced reactor iscomprised. Within the. reactionchamber there is some coursemedia to help. This simplicity of. DIY. concept. The imageto the right shows one example of a. DIY Forced Reactor. It is simply comprised of a powerheadwith prefilter, and gravel cleaning tube,a course filter. The cost to build this, if youwhere to buy all the parts,is inder $3. US. More details. Additional Concepts and Designs. Sincewe are dealing with solids, liquidsand.

Yeastie the Beastie! Yeast is the primary ingredient in our DIY CO2 generators. Common bakeryeasts are. CO2 generators. Yeast is a livingorganism and optimal living. I had to touch upon thisin this text. Also. knowing there are as many strains of yeast as there aredifferent algae, I have to touch on that also. It is also. good to understand the biological processesinvolved here, and. I will discussthis firstly. Theodor Schwann(1. Most yeast used is of the budding. Although easily grown in culture media,each. S. However, in a given culture onlyabout half of the cells. The process offlocculation. Yeastsare probably the most researched organismsin microbiology. Entire scientific communitiesand. If you want to blow your mind out one day, check out. It is a list of researchers, their. Saccharomyces cerevisiae. This yeast. has the distinctionof not only being the one wegenerally use for our CO2. DNA)completely mapped in 1. Yeast Labs. and Research. Thisis only for the brave of heart! A morepragmatic description of the biologyof yeast is given. BIOLOGYYEAST: A living organism formed of onlyone cell. Many othersugars are also utilized. Aninteresting scientific work by Vern J. Elliotshows the utilization of sugars by yeast,and yields some. If you look at the chartbelow you will see growth ratesof yeast over time when. Justto understand the chart, the reference ofthe test is as follows, (for you technicallyoriented. Plates (growth samples) wereincubated at 2. Itcan be reasoned that the yeaststrains we use in our. CO2 systems would have similar. Sowhat does this mean. Essentially,using less. CO2 mixture. Conversly, CO2 quantity measured over time is another. Longevity of the yeast culture. Acids play a much lesser role in. More. on this later). So, useof sucrose seems to be a betterchoice, other factors not withstanding, than othersugars. Theconditions of oxygenation of the environment generate. In AEROBIOSISWhenyeast is in presence of air, it produces,from sugar and oxygen, carbon dioxide, waterand a. It is the metabolic processof respiration. In these conditionsthe oxidation of. Glucose + Oxygen . Thanks to thisenergy, yeast. But it can also use it tosynthesize organically, that isto say start its growth. It willthen have to find other. In ANAEROBIOSISWhenthere is no oxygen available, yeast cannevertheless use sugars to producethe energy it needs. Pasteur defined this metabolic. Sugars. are transformedinto carbon dioxide and alcohol. The glucose oxidation is incomplete: Glucose . But aerobiosisis also. Many of. theseorganisms were discovered more bychance, than. Other typesof yeast and bacteria arealso utilized in variousstyles of beer and brewing beer. Thefollowing is a description ofthe many. CO2 generation. Some are commonly availableand inexpensive; some are harder toget and more. Theadvantages and disadvantages of each type. Bakers Yeast. Bakersyeast (or Dutch Process yeast) is widely available. It isdried active. Most. of usknow bakers yeast, popularized by companieslike Fleishmann's. They manufacture little packetsor you. It comesin several variations. Regular. bakersyeast in 7- gram packets is by farthe most. Lately a newform known as . This yeast is moretolerant of higher. Both work wellin our application. It is. foundin the dairy or deli case. Compressed yeastis available to commercialbakers from a variety of. Compressed yeast has. It is highly perishable and must bestored at a. It has,however, been.

To rehydrate instant active dry yeast, blendone- part yeast with five partslukewarm water, wait 1. Itis worth noting that there isdisagreement. The most convincing argument against freezingis that.
