OK to add water during end of cycle process ?

Adding water is fine. In fact, after your fissless cycle, you have to change a lof of water to reduce the Nitrate concentration. Remember that the bacterial filter turns ammonia into nitrite and then into nitrate. If you have a test kit, check for nitrates and they must be fairly high. Keeping them less than 20ppm is excelent. Nitrate is not as toxic as ammonia or nitrite but has to be kept low.

When you perform your water change, remember to use a declorinator before adding it ot the tank. Chlorine can kill your bacterial colony.

About fishes, once cycling is complete you can add fishes. In fact, if you let the cycled tank with no fishy the bacteria will have nothing to eat and will die. You can add 2 fishes, wait a week and add two more and so on until you reach your desired stock.

If you add too many fish at once you might end up with more ammonia than your filter can handle. Remember not overstock your tank capacity, and your filter will adapt to your fish load.

Hope this was helpful to you, and good luck.

Happy Thanksgiving!!! I wouldn't worry about adding water to either, it shouldn't affect your numbers at all, just make sure your added water is declorinated.
If your getting 0 then you can add fish, but if you'd like you can wait a day just to make sure your numbers stay at 0. Also, what kind of fish are you planning on getting btw, if you don't mind me asking.

Looks like patoloco finished writting his response first, and is better explained. Lisen to him. or her? Listen to it.

Depends on how much of each you plan on having. I have 8 white clouds for a schooling fish. I also have a german blue ram. It kind of depends on what you like then you got to find out how big they get and if they'll be nice to everybody. I really love the german/gold rams, but I hear they can be hard to keep alive sometimes. I just got mine yesterday, and so far so good. still wating for her color to come back though so no pics yet.

Umm. I dont know but he didn't mention doing a fishless cycle. Cribbinator you DID add some ammonia to the tank right? Because if you simply had an empty tank with water running in it then of course the ammonia and nitrite will be zero. If you were doing a fishless cycle by adding ammonia then you should be okay then.

The first post stated "ammonia and nitrites finally 0", so assume there was ammonia and nitrites at some time.

For a 29 galloner, i'd put 3 gouramies (1 male, two fem - top swimmers), 4 rainbows (middled) and 3 corys (bottomers).

A gourami ratio of 1m-2f is good for cutting the male agression. Cories do better in groups. As for rainbows, I just threw a number that would "fill" the imaginary space in my head. Do a little research an rainbow's requirements to get a better number.

Remeber to add them little by little. You could surely start with the gouramies since they are pretty hardy, so they will better tolerate any unwanted situation. If after 1 week, everything is going normal, put in the cories. And after that, add your rainbows.

What kind of rainbows we talking here? Boesemanis go between 3.5 and 4+ full size. That's a lot of fish for a 29g. I have 5 2.5" in my 36g and they are getting cramped.

Seriously don't think Boesemanis should be in anything smaller than 50 gallons based on my experience. If you are planning on upgrading eventually, you'll be fine for . . I'd say about 6 months. They grow pretty fast from what I've seen of mine.

I emailed LiveAquaria.com today and *****ed them out for having 4" rainbows in a min 20g. They even had one 6" rated for 20g! They are schooling fish.

Also, watch your male-female ratios. I've learned recently that once they get sexually mature they get awful nippy if there aren't enough females to go around.

Just my 2cents
