can't keep these????

ok so i have had my tank up n running for about two months n my fish are doing great!! however i have gone thru 2 cleaner shrimp 2 peperment shrimp n numerus snails..... have bo idea why.. i use ro/di water so i shouldn't have any copper.. any ideas???

 

what fish do you have? also, what are your parameters?

 

Most shrimp require stable water conditions that a tank that young cant provide.

 

What size tank, what fish are in it? And where did you get the tank, new or used? If it was used, there is a chance someone could have dosed copper :-/

 

coral beauty
2 damsales
2 clowns

amm 0
nit 0
ph 8
pho .25
alk 12
nitrate 20
salinity 1.024
cal 520

 

30 gal (upgradeing to a 135 n bout two weeks)
i've had the tank for years n got it new

 

Are you dosing anything? Your calcium and alk seem high for 1.024 salinity. Not that those should affect shrimp or snails directly. Can you test magnesium?

 

Gosh it sounds like copper to me. Cleaner Shrimp are actually pretty hardy critters as well as those snails but they all seem to be the first to go when copper is present. Is there a possibility that this tank has ever had copper in it. From freshwater days, possibly.

 

uuummm.... i never put any in... no i cant test mag or iodine yet eaither.. i did start the tank with reguler tap water with additavies n the salt mix i use is soupose to remove copper... will try n get a test for copper tomarow scince that seems to be the closest answer.. thanks guys. oh n no i haven't been dosing anything... i was dosing purple tech purple coralline only twice n knowticed that my cal was high.. i have no corels to use it up so i stoped useing it for the time being...

 

Leave the purple up, alone. As long as your alk, ca and mag are all in good range; you will not need to use that stuff. My tank is completely covered and it's only 6 months old now and I have never thought of using that purple up stuff.
