Dead Snails, crabs, and damsel... Help

[superdave07]

My 20g tank finish it cycled my on June 9, 2011 and two days later I added a cuc and a damsel. From the start the damsel would hide, hardly come out now its been about 12 days and hes missing or hiding very good and most of my snails died and also my crabs, I have the about 5 snails left and some dwarf cerith alive, one or two crabs. What can be the problem? I want to add a pair of clowns but not sure if I should. My test kit is dated 12/10

When I started the fish tank I used tap water with conditioner and I did a 30% water change last weed with distilled water and yesterday I did a 50% wc with distilled, my Trate where at 25 now they dropped to 10

How about using di water for my WC it's a 20g tank

what do you mean by di water? Do you mean ro/di water from a machine? Where did you get the water?

I'm sorry distilled water

 

[carey]

Ahh i see now. I wouldnt continue using that, just what I've heard. Do you have LFS that sells ro/di water? Or can you swing about $75 for your own unit?

To be honest, I don't know specifically. It's just something I've read here on the forums. If you have a Publix or a stop n shop grocery store they usually have the machines out front that you can get water from for about 30 cents a gallon. Can't beat that.

You think the water is at fault for the deaths?

I really wish i had an answer. Don't wanna just guess, but if I had to guess I'd say no probably not. But that's only a guess. Someone will come along and explain I'm sure, it's still early yet.

Lower your nitrates to 5. Make sure your water is oxygenated.

What's oxygenated? I've done two WC to lower the nitrates, any other way to lower it?

 

[cls8s]

Change the water again, 20% or so. You need to make sure your water has oxygen in it. If you have a somewhat larger tank, the filter alone won't do. I have a 37 tall and have two Koralia 750's in it to provide water movement.
