Just to clarify Matt, the book I was paraquoting does mention that acidosis/alkalosis does not just happen just in the extremes or fast changes to ph, it can also happen with acidophiles (fish that are normally under 7.0) in alkaline conditions of ph8+ or vise versa. Therefore discus, which are acidophiles, when kept in ph8+, can experience alkalosis. Africian cichlids would be another example if kept in acid (under ph7) conditions.
Well, I know that you understand this and I do agree with you in that "some fish just wont tolerate some PH's, but those fish are less than those who can tolerate it."
To be honest, when I got my first tank, a 30G, I filled it with water and 3 days later got 6 neons. I had actually never heard of a cycle or ph etc. It was a couple of weeks after that I really started getting into the water parameters that I discovered my mistakes. Now I would like to help others in the same shoes. Once you have one tank cycled, as Matt mentions, cycling no longer is a problem.
Mike,
Betta in a bowl! Depends on how big the bowl is? You talking like 1/4 G? lol!
"the more bio capacity of your filter the larger the colony,that way the bacteria multiply quckly when you add a load on the tank.if you have to cycle with fish,dilution is the key to reduce fish stress at this time"
The bio capacity also depends on the amount of "food" (ammonia/nitrites) availible. Once your culture starts growing and multipling, it will stop when the 'food' is gone. Therefore, when adding a couple of fish to cycle, the culture will be very small. In fishless, you can grow as big a culture as you want, providing of course as you mentioned the bio capacity of your filter. However, bacteria will not multiply any quickly just because it has 10x the space availible. No food, no growth. With fish cycling, dilution will reduce the amount of food therefore the culture will not grow as big. Even though I do agree with you that one must reduce the stress on the fishes, I dont like the idea of reducing the food thus reducing the culture.
But you may already know this Mike but I thought I would 'clarify' just in case! *thumbsupsmiley*
