you take out the water (50%). then you start filling straight from your highly chlorinated tap. as you begin, you add a squirt (I'm guessing about 10-20mL). then midway through the filling you add another squirt. and you check your temperature midway through to make sure it's still the temp you want (minor fluctuations during the filling, you mentioned, are okay?). and adding too much conditioner doesn't hurt anything, right?
Within reason, correct. I don't overdose conditioner excessively--first it wastes money, second it is a foreign substance entering the tank and while essential for its intended purpose of detoxifying chlorine and metals, there is no point in over use for no purpose. And notwithstanding most manufacturers say it cannot be overdosed, I'd rather not test their claim.
The "on contact" is an uncertainty for me. Clearly chlorine burns fish gills. But in a 90g tank that is half empty, the fish are easily able to escape the chlorine-heavy water and they have the instinct to swim away from danger. Also, the conditioners clearly work within seconds, as my experiences have shown. It takes about 30 seconds after starting the refill for me to use the conditioner, sometimes even a minute or two; I've never noticed any problems. The "squirt" is my holding the smaller bottle (with the squirtable top
) upside-down and giving it one moderate squirt.
As for temp, I usually aim to cool the tank by 1-2 degrees for the SA fish. This stimulates the fish, it replicates a tropical rainstorm. If you do this on a day when there is a low pressure system outside, you will probably have spawning that evening, if the fish are in condition. A major water change with cooler water is often used to spawn difficult species like Corydoras and many characins.
In my SE Asian tank, I aim for equal or slightly warmer temperature, because I have two species of highly sensitive Chocolate Gourami (which regularly spawn, they are young fish and first 12+ spawnings are normally unsuccessful but I have a baby now in fact among the floating plants) plus my pygmy sparkling gouramis, and these fish do not appreciate being chilled. Chocolates are highly prone to skin parasitic infestations brought on by chilling.
