Hi there. Just joined this forum. I am starting a nano Marine tank.
It has been going with liverock for 6 weeks now. Tried twice to add livestock:
1st A cleaner shrimp died within 2 hours 2 weeks later a damsel also died in 2 hours.
Cycle comeplete because no amonia and nitites in tests. Salinity about 0.26. Temp 25.
Any ideas.

Hi, welcome to MASA, sad to hear you are having problems, how did you acclimatise your fish and shrimp?

You say no ammonia or nitrite, how about nitrate or phosphates? did you test for them?

masahello

Sorry to hear as well, dont think it would be copper, if it was the fish should have been fine

Salinity seems ok, What are you using to test.

Tell us more what substrate have you got in the tank?

What filtration, to be able to help we would need more info, even pics

Welcome to the forum.

How did you add the livestock to your tank? Did you float the bags in the water etc.?

Are you using synthetic salt or NSW?

Ok I have crushed coral for substrate about 1-2mm not to fine. Did test for Nitrate but not phosphate. My test kit is the same one I use with my tropical(freshwater) tank. Nitrate did register a colour but nothing sugnificant.
The Shrimp I put the bag in the tank sealed for 10min them opened added about a cup of water with 10 min intervals and then set it free.
The Damsell I kept closed 30 min then opened and added a cup of my water every 10 min 5 times and let rest another 20 min. I also added an airstone in the bag this time.

The water is tap water treated with a tetra product to take out chlorine and heavy metals. Natural sea salt bought from petshop for marine tanks was used for the salinity.

Oh yes any suggestions for good marine petshops in Cape Town pref. Nothern Suburbs?

Hi there Toothsmith! Welcome to MASA! Also - sorry to hear about your losses.

I think that your salinity/SG might JUST be a little too high. Try bringing the salinity down a little bit. Find out from your LFS where you purchase your life-stock from, what the salinity, temperature, nitrates, nitrites, ammonia, pH, etc parameters are that they are keeping the life stock in before you purchase them. It might be radically different to yours.

I know that a lot of LFS's usually (by default) have their SG/salinity at +-1.020 for fish and +-1.023/24 for inverts....

BUT just check with your LFS, and then make sure that you get your water closer.

Alternatively, you SHOULD acclimatize for a much longer period. The longer you can acclimatize your fish AND inverts for, the better.....

Sorry - I only saw your post about the LFS's in Cape Town, after I posted...

Please have a look at the following link:

I agree with Sparky's link. I think you were not taking enough time to acclimatise and you are adding to much tank water at a time. How have you tested for your Salinity. The swing arm meter is unreliable at best. Also, do not use an airstone as this may have an effect of the P.H. in the bag, increasing the P.H.

Welcome Toothsmith, sorry for your losses. Get away from the tap water, going cause you loads of problems.

Damsels are normally bullet-proof, so there must be something hugely wrong.

Shrimps need to be acclimatized for at least 3-4 hours.

This forum will definitely get you up and running the right way, and remember in this hobby everything is done slowly.

Welcome Toothsmith.

What brand is this "natural sea salt"? Tap water is pretty bad, even when treated with stuff for chlorine etc (that possibly makes it worse). You should try buy some RO water from your LFS (although the ones that's been advising you so far doesn't seem like a good choice)
