How to restart a marine fish tank?

[src7014]

Hello! I need advise here.

Recently I started a new tank that runs well for 1 month with fishes swimming happily. Howvever 1 week ago I brought a anemone and the next day the anemone was sucked under my pump and polluted my tank! All the inhabitants die soon after. Please advise how can I restart the tank ? draining off the water completely and filling with fresh per-mix salt water can ?

Hello Tuna,

I have another question.

My other tank has completed the nitrogen cycle?

I tested my tank and has detected zero reading for ammonia and nitrites but after I introduce a few fishes into the tank and on the 2nd day my test for nitrites went from light blue to purple (2.0 ppm).! I used API test kits ! but ammonia was clear! the fishes are still alive but why? Do I have to try to get the nitrites down to "0" light blue and alway keep it "0"?

Regards

Ronnie

Anemone is not recommanded for a new tank, since it is not easy to keep. I would suggest for a major water change with salt mix ( Mix the water at least for 24 hour) or Sea water. You could also use carbon or poly filter to remove the tonix from the water.

Appreciate your advise! I already did that ! Thanks !

Btw do have similar experience here. My other 4ft tank which has completed the cycling. zero ammonia, zero nitrites and nitrates! during the cycling I noted a spike in ammonia and nitrites.

I tested my2nd tank and has detected zero reading for ammonia and nitrites but after I introduce a few fishes into the tank and on the 2nd day my test for nitrites went from light blue to purple (2.0 ppm).!

your 4ft tank should have been cycle successfully since you have notice the spike in the ammonia then the fall. For your second tank, i advice you double confirm the nitrite reading with another test kit ?? You can check out Salifest test kit .

My tank has been revived and now into the 6th month. Patience really paid off. I almost wanted to give up this hobby.

This is the first time i am posting my tank picture here.
