What's the optimal ph level for these fish?

Question

-1 betta
-3 cory cats
-6 neon tetras

I don't mean each individual species, but if they were in one aquarium, what would should the ph level be at.

Answer 1

As long as it would be within the range of 6-7.5 they should all be fine. They don't need an "exact" 7, or anything like that. The range could probably be even wider, but the neons would prefer more acidic water than the others.

It's better to have them slowly acclimate to the pH of the water you have than to continually try and change it and stress the fish every time you do a water change.

Answer 2

In an ideal world, I would guess around 7.0 because that's the preference of the neons and the cories but I think the betta prefers it a little harder. But realistically, it's more important to not be altering the pH much. If you are using treated tap water, all of these adjust to a wide range of pH and should be fine with the pH of your tap. It's a lot harder on their system to use additives to try to maintain a pH that will fluctuate with every water change.

Answer 3

They could tolerate as low as 6.0 and as high as 7.5, but probably would be most happy around 6.5-7.0. The actual number isn't as important as stability. You can't have 7.0 today and 6.5 tomorrow playing around with chemicals.
If it is within the range, don't worry about the number. As the tanks mature, the pH tends to drop. Waste is acidic. This is one reason why you need to do regular water changes. If your tap water is 7.0 and the pH has dropped to 6.5, a 20% water change will bring it back a bit. If it dropped that much, you were probably way overdue for the water change. After 2-3 water changes, you will find your numbers back up and bi-weekly changes should keep them steady.

Here's the profile for the betta: http://www.aquaria.info/modules.php?file=speciesdetails&id=190&op=modload&name=database

In general you shouldn't really worry about the pH of your tank. Virtually all fish in the aquarium hobby will do fine in a wide range of pH, as long as that pH is stable. I would recommend that you NEVER use any products to modify the pH of a tank as a stable pH is far more important than the "perfect" pH.

Answer 5

that's maximum suitable to not mess with the pH point. maintaining it sturdy is greater significant that maintaining it impartial. For the fish you're looking at you will prefer to maintain the temperature interior the intense 70s. that's maximum suitable to maintain ammonia and nitrites at 0ppm for the well-being of the fish. that's oftentimes finished by ability of making specific you have totally cycled the tank in the past including the fish and by ability of appearing recurring partial water transformations and tank cleanings. Nitrates would desire to be under 25ppm, yet decrease is often greater suitable. you may save the nitrates down with familiar tank upkeep. in the adventure that your faucet water is already intense in nitrates you may minimize it with opposite osmosis water. intense nitrate levels will bring about intense algae boost.

Answer 6

7.0 should be good but I think Bettas like it a little higher.

Answer 7

6.8-7.2 neutral water is always better.
