[terryansimon]

merely speculating. but did you notice any dead or MIA fishes?

[Terryz_]

MAybe juz a minor spike...

[ReDDeviLs]

nope no dead fishes at all,but theres a dead shrimp that i bought yesteday and died today..saw it kerna shock last night.

[terryansimon]

that could be the cause. but merely speculating, like I said previously.

[ReDDeviLs]

I think the filtration system of your tank is not mature enough to handle the bioload.

NO2 should be zero before you can introduce live stocks.

Think you have to be worried......if it is still going up then you will lose some of your fishes.

One way is to cut down on the feeding and change water frequently so as to reduce the NO2

Can you move some of your livestock out temporarily for a few weeks at least?

If you keep them there, the nitrites will kill them in no time.

Your filtration system needs to catch up with the bioload... and as Prof Morgan says... maturation of new tanks' filtration system does takes time... so stock slowly.

It's a common newbie mistake... Don't worry!
