SW is a buffer. That`s why frequent PWC`s will buffer your tank water.

Well, it was sitting 3 days after mixing. I dont check right after mixing.

Okay, then your dKH is just a little high then. Not out of range at all, and I'm sure once you add it to your tank and it starts getting "consumed" the number will level out a little.

I came to the conclusion that the instant ocean salt must be causing my cyano. I siphoned out the cyano last night, did a 25% water change and this morning it was worse than before. Im running Phosban in the Phosban Reactor and my parameters are as follows.

Nitrates=..05
Nitrites=0
Phos=0
Ph=8.1
dkH=19
Cal=480

Im going to Big Als tomorrow and I want to know what salt i should get and why? Please help me out here. Also, I am thinking of adding seltzer water to my tank to lower dkH. Look forward to your input.

What are you dosing your tank with? Calcium levels of 480 and alk of 19 don't come naturally with Instant Ocean and RO/DI water.

Lol. Everyone has asked me the same question. I dont dose my tank. THat is what has perplexed me from the moment i started testing for alk. I was reading that Red Sea has an alk of 2.5 after mixing with RO/DI. ANy thoughts on this? I am getting ready to go to Big Als in 20 minutes.

The alkalinity isn't really why I said that. Using pure water (RO/DI), your Instant Ocean should mix up between 340-360ppm, from my experience. If you're using tap water (no RO/DI), then I can see your Ca levels being higher because you have the additional Ca that's in the water to start with. But you're using RO/DI water, right? And the fact that you tested your RO/DI water and you're getting 0 dkH for your alkalinity leads me to believe that your membranes and resin in your RO/DI are OK. So that extra Ca is coming from someplace, or your test is giving you bad results.

Regarding the alkalinity numbers you mentioned, you're mixing apples and oranges. The 2.5 number you quoted is in units of meq/liter, but the numbers you're getting from your test are dkH. Totally different beasts. To convert, 1 meq/liter is equal to 2.8 dkH. Soo... that 2.5 number you quoted for Red Sea is the same as 7 dkH. (Still a little low for a reef.)

Something is weird with your water, and personally I'd try to figure out what it is before changing things randomly. Salt mix doesn't "cause" cyano. Some salt mixes might inhibit the growth more than others, but the basic cause isn't the salt, from what I've read.

Thanks for replying Kurt. I went to Big Als a little after my post and I bought the Red Sea Salt. I tested my RO/DI water before adding the salt and I got 0 dkH. NO2 & NO3 NH3 all 0. I added the Red Sea Salt and I got 5 dkH NO2 NO3 NH3 all 0. PH=8.4 . From what I am gathering so far Red Sea is far more stable than my IO Salt i was using. I dont know why I am getting those results with the IO. Maybe i got a bad batch to begin with? Either way, I am going to scrub the Cyano off of all my Rock 2morrow, do a 30% water change and rescape the tank. THen i will monitor the tank over the next week or so and see how it does. So far I am very happy with my purchase. I got a bucket of Red Sea Salt (250ga mix) for $45. BTW Nikki, I asked for you but they said you werent there. Maybe the next time i go i can finally meet you. Even my wife asked if you were there. Lol.

I have to agree with Kurt on this there is something causing the odd readings. I think I would invest in some new test kits. They do have expiration dates. Get a couple of new test kits and see what your readings are. I switched away from IO because of continued Cyano also, but as Kurt said the salt mix alone isn't the issue.

Well getting new test is out of the question because i just bought a new Hagen Master Test kit about a month ago, and i had a salifert master reef test kit that measures the same. Like i said, i might have just gotten a bad batch of IO. Either way, im done with IO.
