The recommended Ph for a community tank is 7.0 which is neutral between alkaline and acidic.
Water will always have a pH. pH is a measure of how acidic or basic a solution is. Intruduction of basic substances such as carbonates will raise pH. Introduction of acidic substances such as carbonic or sulfuric acid will lower pH.
The density and pressure of saltwater is different from freshwater as is much of the bacterias and parasites. The acidity of the water is also of concern as the lower the PH the higher the acidity of the water. Saltwater being of a higher PH would not handle the lower PH of freshwater very well. Also if moving a freshwater fish to saltwater that fish will lose a great amount of water in it's body causing death and if the saltwater fish is moved to freshwater it will gain great amounts of water causing death.
It depends on the type of fish and plants that are in the aquarium. For most tetras, danios and swordplants, a pH of 6 is preferred. For guppies, platies, swordtails, hornworts and cichlids, a pH of 8 is ideal.
A pH of 8 indicates that the water in the fish tank is slightly basic. This pH level is suitable for most freshwater fish, as they typically thrive in a range between 6.5 to 8.5. However, it is important to monitor the pH regularly to ensure it remains stable for the health of the fish.
Seawater has a higher concentration of salts and minerals compared to freshwater. Seawater also has a higher density and freezes at lower temperatures than freshwater. Additionally, seawater has a higher pH and different composition of dissolved gases compared to freshwater.
The pH of seawater is typically higher than freshwater due to the presence of minerals and salts, which can buffer against changes in acidity. Freshwater bodies are more vulnerable to changes in pH because they lack these buffering compounds. Human activities such as pollution and acid rain can also contribute to fluctuations in freshwater pH.
There are a variety of elements in all water. Each element carries with it a specific PH. Salt water maintains PH ranges anywhere from 8.4 to 7.6. Fresh water carries different elements and the PH range can become lower, down to as low as 6.0.
The best PH level for cichlids is 6.8-7.2. In discuss cichlids, this level will be much lower (pleas note- discuss are VERY hard to keep).
Depends on type of tank you wish to keep, rather more aggressive or community, higher PH or lower, cold or warm, completely fresh or brackish, etc. Your best would be to choose a type of fish you like the best, then research which fish can be with that fish.
Freshwater typically has a pH ranging between 6.5 and 8.5, which is considered slightly acidic to slightly alkaline. This pH range allows freshwater ecosystems to support a variety of plant and animal life. Any significant deviations from this range can have harmful effects on aquatic organisms.
DON"T DO IT!!! Why on earth would you want to do something as drastic as that?Adding even a tiny amount of pure concentrated H2SO4 to a tank containing fish is begging for trouble. You are more likely to kill (from pH shock) your fish and every other living thing in the tank than do anything else if you add any amount of H2SO4 to it. Go to a good garden centre and get some PEAT MOSS (product of Sphagnum Moss). It must be the real thing and not any kind of modern (Coir) substitute. Place some of this (pre soaked) peat moss in a stocking and put that into your filter (Or a corner of the tank) so that the water can run through it. It will slowly and gently and naturally lower the pH. It will also lower the GH/KH/DH slowly.
