tank has been up for 3 months

PARAMATERS

ph 8.3-8.4
ca 480
mg 1600
alk 11
phos less than or equal to .20
temp 80F
nitrate 0

ten gallon sump/fuge running a skimmer

5-6 gal fuge nearly full of chaeto and gracillia

generous portion of carbon
chemipure elite



lost a clown today (seem to have a white haze on him 24 hrs before he kicked the bucket.)
and a lawnmower died before the water change


i been doing this for a few years... i donno what gives

Sounds dumb, double check the salinity, check calibration on it. Mine was off by .008

 

[doubleott05]

Ok ill do that. Salinity was .26 yesterday. Did all the other tests righbefore this post.

 

[timkatz71]

When is the last time you checked the calibration on it?

 

[doubleott05]

Never did. It is a coralife. Never needed it.. i never calabrated one in ten years. I have lost fish on foew occasions... The only reason that this is significant to me is because it happened in such a short time frame maybe 3 or 4 days apart

When was the last fish added to the tank? Quarantined?

 

[doubleott05]

no but they have been in there for over two months together.

Were all current fish purchased from the same place? By the way, the more information you can give us, the more likely we are to figure out the problem. A white haze suggests parasites.

why r u using carbon and chemipure elite?

this is why i posted so you can pull info from me that im not thinking about.



all but one came from the same store.

both the fish that died came from the same store.

why r u using carbon and chemipure elite?

...... why wouldn't i?

It has carbon and GFO in it.

 

[timkatz71]

I think that I read somewhere to only use carbon for a short time after water change unless in a reactor if I remember correctly

 

[timkatz71]

I stopped using it and haven't had issues since

 

[doubleott05]

is water flow through the carbon a debate?

 

[timkatz71]

I think that what they were saying that once it was exhausted it becomes toxic but I could have misread. That is how I took it and removed immediately, I throw a couple cups in a media bag for about 24 hours after a water change

 

[doubleott05]

Well im upgrading to a 50gal im building it as we speak I'm hoping I won't need to use carbon in this set up cause I'm going to do everything by the book except there is no book....

 

[timkatz71]

Lol, yea I know that one, we just bought a house, so of corse... New tank was also purchased. I have about 6 weeks to do my planning for the 225 that I just bought, the 120 and 55 as well, plumbed together

 

[doubleott05]

Gonna start my journal thread soon. Im working on the stand currently
