1st I need to ask, is there a water holding tank with these setups? I do not use a holding tank on no aquarium all there is is just the aquarium no holding tank. 40g per day = 240g every 6 days he did state daily in a 225g tank. All aquariums go thru a Nitrogen Cycle, the nitrogen cycle converts organic wasts ( ammonia and other nitrogen compounds ) into beneficial plant fertilizer (nitrate) the process of an aquarium is Nitrification, refers to the degradation of harmful nitrogen compounds by nitrifying bacteria. When inorganic ammonia is present, (NH3) is present bacteria (nitrosomonas sp.) convert the ammonia to nitrite (NO-2) other bacteria (nitrobacter sp.) consume the nitrite and convert it to nitrate (NO-3) a relatively harmless compound that is the highest oxidized form of the nitogen. As a result, harmful wastes are converted into nitrates that benefit plants.
The Nitrogen Cycle. Wastes produced in the aquarium consist primarily of ammonia and other organic compounds. The organics break down into ammonia, which is reduced by nitrifying bacteria into nitrite. Some nitogen blows out of solution as a gas, but most is further reduced by bacteria to nitrate. Some of the nitrate is consumed by plants as food, but most accumulates in the aquarium and must be deluted by regular partial water changes. Nitrifying bacteria grow on all surfaces in the aquarium. These bacteria must adhere to some surface in order to do there job. They also require oxygen in order to convert ammonia and nitrite. In fact the more oxygen available to these bacteria, the faster they preform.
These bactreria is what one can destroy and leave none to very little bacteria within the aquarium by over changing the water.
You'er joking right?
an inaccurate explanation of the nitrogen cycle ? Really?
couple of quick questions...what's the difference in aerobic and anaerobic bacteria as it applies to the nitrogen cycle?
Why is surface area for the colonization and proliferation, of benificial bacteria so important when selecting Bio-media like SCRUBBIES?
Did you know that 500 gallons per week, that is dripped at a rate of 2.976 gallons per hour into a 225g tank, NEVER will reach 100% water change, ever...
The ongoing nitrogen cycle in our biologically filtered aquariums actually have colonies upon colonies of Beneficial bacteria being produced and dying off at all times, it's what keeps the bacteria healthy.
The easiest way to remove NitrAtes from the tank is by doing water changes. It has been proven time and time again that large regular waterchanges using dechlorinated water will not effect the nitrogen cycle...
just ask any serious Discus keeper.
The real problem with doing rather large waterchanges is the swing of Ph.
I would have to say, water changes that are on an erratic schedule is what causes the Ph shock, that is detrimental to the fish.
Free swimming water-borne beneficial bacteria count is nothing like the bacteria count on the surface area of your Bio-media.
If the above statments are true, how can you flip the PH from high to low and back to high again, without adding anything to the water? and why would you want to?
RO water mixed with dechlorinater tap water can easily change the TDS of the water, but it won't be Ph stable until there are enough bufffers to hold the hardness...
This fishkeepers saving grace is the fact my fish have been acclimated to the tap Ph. Should I ever experience a total meltdown of my filtration system, for what ever reason, like multi-day power outtages, I can put some Prime in the tank and turn on the hose and my fish and fry will be fine. Then upon the restoration of power, I can then clean out the Media and use a bottle of SeaChem's STABILITY and in 1 weeks time can be right back on top...
