The effect of light on seed germinationWhat is Transpiration?

Aerating the water, driving in carbon dioxide, is shown graphically in Figure 5. As carbon dioxide is added, the data point representing the aquarium's pH and alkalinity begins to shift horizontally from the "CO Deficient" curve to the normal CO curve (green line in Figure 5). Aerating with normal air cannot overshoot, and perfect aeration will land the aquarium on the normal CO line. Aeration with interior air that may contain excessive carbon dioxide can overshoot the pH target, and drive the aquarium's pH even lower (Figure 6).

This is because carbon dioxide is one of the reactants for photosynthesis.

Effect of different colors of light on the rate of photosynthesis.

In practice, any one of these factors could limit the rate of photosynthesis.

I recommend adding 6 mL of soda water per gallon of tank water to reduce pH by about 0.3 units. Add it to a high flow area away from organisms (such as in a sump). The local pH where it first is added will be very low. Going about this procedure slowly is better than proceeding too fast. If you do not have a sump, add it especially slowly. Some soda water may have more, or less, carbon dioxide in it, and the lower the aquarium's alkalinity, the larger will be the pH drop. Also, the higher the pH, the smaller will be the pH drop, because the buffering of seawater declines steadily as the pH drops from about 9 to 7.5.

A. Direct addition of carbon dioxide. Bottled soda water (seltzer) can be used to instantly reduce aquarium pH. Be sure to select unflavored soda water, and check the ingredients to be sure it doesn't contain anything that should be avoided (phosphate, etc). Many manufacturers list water and carbon dioxide as the only ingredients.

That the calcium level is at least 400 ppm. Calcification becomes more difficult as the pH falls, and it also becomes more difficult as the calcium level falls. It would not be desirable to push all of the extremes of pH, alkalinity, and calcium at the same time. So, if the pH is on the low side and cannot be easily changed (such as in an aquarium with a CaCO/CO reactor), at least make sure that the calcium level is acceptable (~400-450 ppm). Likewise, one of the problems at higher pH (above say, 8.2, but getting progressively more problematic with each incremental rise) is the abiotic precipitation of calcium carbonate, resulting in a drop in calcium and alkalinity, and the resultant clogging of heaters and pump impellers. If the aquarium's pH is 8.4 or higher (as often happens in an aquarium using limewater), then it is especially important that both the calcium and alkalinity levels are suitably maintained (that is, neither too low, inhibiting biological calcification, nor too high, causing excessive abiotic precipitation on equipment).

That the alkalinity is at least 2.5 meq/L, and preferably higher at the lower end of this pH range. This statement is based partly on the fact that many reef aquaria operate acceptably in the pH 7.8 to 8.0 range, but that most of the best examples of these types of aquaria incorporate calcium carbonate/carbon dioxide reactors that, while tending to lower the pH, also tend to keep the carbonate alkalinity fairly high (at or above 3 meq/L.). In this case, any problems associated with calcification at these lower pH values may be offset by the higher alkalinity. primarily by making it harder for them to obtain sufficient carbonate to deposit skeletons. Raising the alkalinity mitigates this difficulty by supplying extra bicarbonate.

what factors affect the rate of photosynthesis?

s discussed above, a reef aquarium's pH rises when its water becomes deficient in carbon dioxide. In practice, this deficiency can be caused in several ways. The diurnal (daily) change in pH in reef aquaria occurs because of the biological processes of photosynthesis and respiration. Photosynthesis is the process whereby organisms convert carbon dioxide and water into carbohydrate and oxygen. The net reaction is:

how does light intensity affect the rate of photosynthesis?

Hypothesis:Photosynthesis is a process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose....

how does temperature affect the rate of photosynthesis?

Likewise, all organisms also carry out the process of respiration, which converts carbohydrate back into energy for other processes. In the net sense, it is the opposite of photosynthesis:

The Effect of Algae on the pH | Healthfully

Equation 2 demonstrates that when an aquarium has a deficiency of HCO, some of the HCO can combine with H, to form more HCO (moving to the left in equation 2). Since H is used up, the pH (which is simply a measure of H) rises. If seawater has a big enough deficiency of CO, the pH can be as high as pH 9 or more.

Prediction: I predict that as the light source (desk lamp) is moved closer to the pondweed (Elodea), the rate of photosynthesis will increase therefore more oxygen will be produced creating more bubbles.
