Low calcium salt mix

[Gordonious]

I need to find a low calcium salt mix for my three 20 gallons tanks that are currently just about FOWLR.(one small yellow gorgonian) My calcium level has been high for a while and I switched from Oceanic sea salt mix to Instant Ocean with a tiny bit of Oceanic. I have done many changes, actually most were just instant ocean salt, and I am not seeing a big change any suggestions?

Unless your adding calcium, Instant ocean should be okay for maintaining a proper Ca level. I prefer not to use it myself for other reasons. What are you using for a test kit, and what is your Ca level now?

what is the calcium level of instant ocean salt when mixed to 1.025 sg?

320/340 range.

The bucket I'm using now tests at 370ppm at 1.026

thx graveyard ... just the regular IO or is it the reef crystals?

anyone know what reef crystals is at?

Regular IO

Reef Crystals has better CA levels than IO. Same company.

I'm testing using Seachems ReefStatus calcium. Currently my calcium level is around 700 at least. I have to re-fill the titrant in order to react with all of the calcium. Off the charts.

Have you checked the Ca level in the new salt mix prior to adding it to your tank? Ca level of 700 sounds really wrong unless you've been dropping in additives. Also what do you use for top off and for salt mixing? You might want to post this in the chemistry forum and see if Randy can give some better answers.

The regular Red Sea salt might be low on Ca.

I had used a good deal of additives after some advice on an unrelated thread before I became more informed about them.
