Transferring fish to new tank question.

[Roland]

Hello I just set up my new 260 gallon tank with 65 gallon sump I have a bubble magus curve 29, two 7 inch filter socks, 120 lbs of live sand and around 150 pounds of live rock. I currently own a 90gal and a 55gal both with sumps "been establish for nearly 5 years". I used around 50 lbs of rock from my established tanks to begin the cycle also around 10 lbs of sand. I also added my filter from my 90 gallon and one bottle of ATM nitrifying bacteria. The tank as been up from 2 week and finished its cycle 2 days ago (all levels are good). Today I did a 90 gallon water change and I am thinking of moving my fish from the 90gal tomorrow to my 260. QUESTION how many of my fish do you think I can move all at once??? Most of my fish are small/med size. Thank you

Beside adding the ATM nitrifying bacteria have you added anything to feed the bacteria, such as ghost feeding or adding ammonia? If not the new tank may not be able to handle too many fish added. Try one or two fish and test for ammonia. If the tank is able to handle that without excess ammonia, more fish could be added.

The method I would suggest, however, would be to get household ammonia and add 5ml a day and wait to add fish until the tank can handle that amount of ammonia. Then you should be able to add most of your fish right away.
