Aquarium Water 'Top Off'

I have noticed a lot of people asking about 'topping off' aquarium water. This means that typically over a short period of time you may notice your aquariums water level going down from the water gradually evaporating into the air. Some people have the impression that you aren't suppose to replace that water in the aquarium, and that's actually not true. If you didn't replace that evaporated water than overtime your aquarium wouldn't have any or enough water in it to sustain its inhabitants. However, you do not want to consider topping off your aquarium water as a type of 'water change' because technically you wouldn't be changing any water.

So now you may be wondering what to do in this matter. Well, you can top off the aquarium water all you like to keep the aquarium from emptying out, but I'd suggest to do a partial water change at this time by emptying out some of the current aquarium water, and then replace that removed water and top off the aquarium in the process. If you happen to notice any of your water parameters (nitrite, ammonia, pH, etc.) aren't where you'd like them to be after testing the water then it may require more additional water changes. Be sure the new water you add into your aquarium is the same temperature or within 3-5°F of the current aquarium waters temperature (or you may risk getting your fish sick with things like ich).

A few ways you can try to reduce aquarium water from evaporating quickly is by keeping a lid on the aquarium, although you still want some openings on your lid so that the aquarium gets proper air and water exchange so that the tank can cycle naturally without causing toxic CO2 buildup. Another thing you can do is try to lower the aquariums water temperature if you do have an aquarium heater, or try adding in an air diffuser to reduce heat. Also insure you don't have any leaks in your aquarium or filtration, and that any air pump tubes used have working check valves on them. If you do run an air diffuser it may make water gradually splash/bubble out of the aquarium if you don't have an aquarium lid.


Happy Nisai

The 1st of January marked my ranchu turning into Nisai so, what better way to start the new year than with another ranchu weigh-in! Also, if you didn't catch it on my Twitter earlier they will be moving into a bigger tank very soon.
Bumblez (left) and Oakki (right)
The last ranchu weigh-in was 3 weeks ago and Bumblez is now 38g, with a 3g gain from the last weigh-in. Bumblez is actually showing his gain for once but unfortunately its not as huge a gain as Oakki. It's no joke, Oakki is almost 10g bigger than Bumblez now which is pretty crazy. Even Oakki's top-view shape seems to be changing more around the sides of his head. So now that Oakki is weighing 47g today, its a 7g gain since their last weigh-in.

I think my goal for Bumblez right now is to have him be at least 50g by the end March, as it will mark them turning 1 year (12 months) old. Do you think Bumblez can do it? I bet Oakki will be at least 60g by the end of March, what ya think?

What's Nisai? Any ranchu born the previous calendar year (making the next year there 2nd year, but not meaning they are 2 years/24 months of age) regardless of what time of month the ranchu was born during that year (yes, even December). Nisai in Japanese means "two year old", but don't let that confuse you!
