I've been cycling my 90 and I acquired some gravel and water from my uncles cycled tank to speed it up. One thing I was worried about was the water got really cold when I was transporting it back home. It did not freeze but I bet it was 50 degrees. Do you think it killed the bacteria?

gee i wonder why u edited your post?????? now that u have a real question.....i would assume that it would kill the bactera but u never know. i would add it to your tank anyway and see what happens. it can only help. what r your parameters, how r u cyclin the tank, and how long have u been cyclin for???

I don't know for sure, but since bacteria-culture products like Bio Spira are kept refridgerated, I'm going to guess that the beneficial bacteria are cold tolerent and shouldn't have a problem with being temporarily cooled.

I've had 8 big mollies in my 90 for 2 weeks, I'm adding a dose of bio-spira tommorow to speed it up more. My question is...I was thinking of buying 5 6 inch caribas once its done cycling. My question is: will the increased bio-load of fish that size cause the tank to re-cycle again? I want it to be prepared.

YOu really should not overstock a tank that much, especially with caribas. The increased bioload could cause an ammonia spike.

How do you suggest I proceed?

The tank probably will re-cycle when you add that many new fish because there will be far more ammonia in the water than the bacteria can oxidize. It will take a while for the bacteria's population to catch up to the new bioload.

Personally, when I am starting up a new aquarium, I only add one new fish (or two small ones) per month. You may want to fully cycle the tank with feeders, then only add one or two fish at a time until you get the shoal you want.

I'm not gonna buy 5 anymore. I'm buying 3 cariba. I kicked up the fish pop in there and now have 14 huge mollies. Its been going for 2 weeks but I'll add bio-spira with the mollies. Then add the p's later ,when its done cycling, and then add another dose of bio-spira =). I think it will work. However, if I would quit being impatient ,and take your advice Bullsnake, it would probably be easier on myself and the fish.
