Is cloudy water part of the new tank process?

I set up a 40g with 1 used marineland cartridge to boost the bio. Within the next day the water go really cloudy so I ran a 75% waterchange. Today the water go a bit cloudy again but not as bad as yesterday. I have no feed ever since getting the new tank setup so there shouldn't be a reason why it would be cloudy. Is the tank going thru the new tank bacteria bloom process? will the cloudy water kill my fish?
 
Hey FnC,

Are the fish you posted yesterday in the tank? I remember seeing your 40g tank thread, but can't remember if the fish were in that tank or not. If so, and with the bio from the cartride, I'm pretty sure the bio bloom is normal "new tank" cloudiness...as you suggested.

I know you know what you're doing so I won't insult you by suggesting testing parameters and continuing water changes :D

Good luck!

There are currently 3 fish in the tank. If the water cloud up more tonight I'll add an air bubbles. I would think the Emp400 would create enough surface agitation to clear out the water.

Funny thing is on my other 20g tank it's crystal clear. This tank was also setup in the same evenning. The only difference is this tank is running on an established HOB filter.
 
Yeah, which sort of makes sense. The established filter has hungry bio. The new tank gets an ammonia spike and the bio go on a feeding/reproducing frenzy. The cloud is the result of this microscopic mayhem :)

would the cloudy water be harmful to my fish? how long should I expect it to clear up?
 
Well, the actual ammonia and nitrite are harmful to fish, the bacterial bloom is not (although you do have to aerate the water more, as the bacteria also use oxygen). Have you tested your water? There's no way to know if you're going through a minicycle unless you test.
 
No, the cloud itself shouldn't be harmful. But you know what happens when bio takes on an ammonia spike...your nitrites go up (and so on). Just keep an eye on your parameters and do water changes as needed to control levels. You should cycle pretty quickly since you added bio to begin with.

I would also give the fish a good look over every so often too. Look for any signs of stress, heavy breathing, etc. Not saying there is anything wrong, but you're well aware of the cycling process and what happens. The water isn't ideal of course with these spikes...but you should be able to control it pretty easily.

Good luck!
 
It's fine
 
Historically the bloom has cleared quickly for me. With the emperor 400, lower the water level a little and let it splash more, this will create more agitation and should keep up the o2 levels.
