At this rate all my SPS will be dead by next week

I'm no SPS expert so I won't pretend to know the magic answer. The frags I got from you are doing great and growing well in my tank and you can come over and frag 'em when you get it sorted out. They're from your colony's so it will be like you never lost 'em. Let me know if you need somethin' I can help you with and hope you get it figured out.

Typically yes. What is you flow through the reactor?

Pretty fast actually - constant flow...



After the Westside Gang showed up here, we came up with following test results:

CA:
600 (Robb/ELOS)
550 (Barry/ELOS)
500 (Cliff/Salifert)

ALK:

5.5meq/l (Robb/Seachem)
19dkH (Robb/API)
21.8dkH (Ansley/Salifert)
21.6dkH (Cliff/Salifert)

MG
1185 (Ansley/Salifert)
1350 (Cliff/Salifert)


So, the parameters are somewhat in check, just ALK is off the chart high
- anyone with a good idea on

a) how to counter steer
b) what caused this?


Thanks Robb
 
My question is, if Alk and Calc are that high, why haven't they started to precipitate out yet?
 
Did you guys mix some of the salt that you have been using and compare the two.
the reason I ask is if you had your calcium reactor set up to adjust one type salt mix it may have been too much for another salt mix with already higher levels.
 
The reactor was dialed in for Seachem, now using IO - so coming from high CA to low CA.
Will check reactor effluent for ALK tomorrow.
 
If it were me I would suspend any dosing or reactor use till your levels get back down. Sounds like your reactor is not adjusted properly.
 
All corals are either at their new (temporary) homes or en route.
Alk will be checked daily until I get it to a normal level.

Thanks to all for your input!
 
Robb-

This is the best reference I know of for describing/diagnosing these issues.

If you add a little acid, it should drop the alkalinity. See below-

[IMG]http://www.advancedaquarist.com/issues/feb2002/chemistry.htm">http://www.advancedaquarist.com/issues/feb2002/chemistry.htm</a>

High alkalinity is known to burn sps tips, and this sounds like what is going on. (although I see no reason why, only water changes-?) JMHO
 
You definitely need to check the freshly mixed water also. I have seen a thread on RC lately where people have been getting 420 calcium 9 DKH and 1350 mag readings out of there IO buckets. If you adjusted expecting lower calcium and Alk this might be the problem.
 
5.5 meq/L total alkalinity isn't bad.

How new is the system? If it's new or fairly new and you're running a sulfur reactor, I am not sure why but my gut says that's likely got something to do with it.

The sulfur reactor was brought online in an effort to fight this problem, so it existed before.

While 5.5 isn't bad - the other tests performed where much higher.

Thanks for the input y'all!
 
True... 5.5 = 15.4 dKH...

Did anyone test the Seachem reference solution against the test kits to see if the tests themselves were accurate?

Clearly something is amiss...

Jenn
 
The saliferts were tested against the 8dkh solution and were dead on.

What's weird is that even a 50% WC on saturday didn't change much...
 
I'm sure you are running a controller on the calcium reactor. Rob it almost has to be the calcium reactor. Does it run around the clock?
 
Reactor runs 24/7,
controller on it too - I decreased the effluent rate hoping to bring the dkh down...

...and, hasn't the Seachem salt/borate issue been addressed somewhat(?) At any rate, I believe that he used IO salt, so that does not apply in this case. The levels below should apply, as is.
