Help needed as Fishes die after changed a new pump

[wearenotmonkey]

I just changed a new pump to drive my chiller but the next day I saw my damsel fish die and a day after another fish die... what could be wrong with the pump? I checked water para and all within ranges ....

[Jameshong]

never experience b4 but did you wash clean your new pump b4 use?

[wearenotmonkey]

just normal water rinse ...

before the damsel die, I observed she just laying and hiding at the rock and breathe heavily...

Sometimes new pumps have a thin layer of lubricant to prevent the insides from rusting.

Either that or there is grease leaking out from the parts... I suggest you give it a good clean (soak in vinegar?) and see how it goes.

But that shouldnt cause the fishes to die.. unless the lub itself is toxic. But i always rinse my new pump before putting into the tank.

I checked the water para today ...and notice the ph os 7.8 ..is that too stress for fish?

Yes ph 7.8 is too low for the fish, buffer it up to ideally 8.3

ok noted and will buffer it slowly and check again thanks..

[wearenotmonkey]

So far everything is back to normal....fishes are not hiding anymore...will start buffer ph bit by bit...so is ph 8.3 good for lps and sps also?

Yes it is ideal for a reef setup as well
