bige Posted August 30, 2013 Share Posted August 30, 2013 I calibrate with the solution and mix to 35ppt. Still had low calcium. But who knows. I tried that new fluval salt that Aquadome was giving away for awhile and it test at 425 calcium. Did anyone see that video that redsea put out about how to mix their salt? They said never mix longer than four hours or the calcium will precipitate. Could this cause low calcium? I've always mixed for 24 hours because I'm a sheep and was told to.

victoly Posted August 30, 2013 Author Share Posted August 30, 2013 Huh, that's weird. I've always mixed overnight. Quote Link to comment Share on other sites More sharing options...
bige Posted August 30, 2013 Share Posted August 30, 2013 Watch it on YouTube. I can't figure out how to link from phone since the YouTube update. Quote Link to comment Share on other sites More sharing options...
esacjack Posted August 30, 2013 Share Posted August 30, 2013 i mix overnight as well.. but i have noticed a build up of precipitate at the bottom of my barrels... i think bio3 had the same issue... Quote Link to comment Share on other sites More sharing options...
bige Posted August 30, 2013 Share Posted August 30, 2013 So would that result in lower calcium? Quote Link to comment Share on other sites More sharing options...
+KimP Posted August 30, 2013 Share Posted August 30, 2013 I thought we were supposed to mix for at least 24hrs to let the ph stabilize? I always mix longer than that and I have a buildup of something in my trash can too. Quote Link to comment Share on other sites More sharing options...
bige Posted August 30, 2013 Share Posted August 30, 2013 In the Red Sea video they say once salt is dissolved the water is ready to use. And should not be mixed more than 4 hours. So I just mixed a batch of fluval salt until all salt was dissolved and which was about 20 min. Calcium was 450! When I mixed over night calcium was 425. I'm gonna test some more.

victoly Posted August 30, 2013 Author Share Posted August 30, 2013 Interesting ! I can echo that I do get kind of a tan precipitate in my bucket. I vinegared it out yesterday. I guess I'll put my mixer on a timer ! Quote Link to comment Share on other sites More sharing options...
Bpb Posted August 30, 2013 Share Posted August 30, 2013 Again...not use RSCP salt, but when I mix mine 24 hours I get TONS of precipitate, and all of my numbers test about 25% lower than they should. I've since started mixing for only 3-4 hours, and all of the big 3 check out at 100% as advertised at 1.026, and the bucket is clean as a whistle. No precipitate. My sps have been none the wiser Quote Link to comment Share on other sites More sharing options...
victoly Posted August 30, 2013 Author Share Posted August 30, 2013 well thats a big win either way. having to test and dose after a WC is a big old pain in the *** that I'd like to mitigate as best I can. Quote Link to comment Share on other sites More sharing options...
esacjack Posted August 30, 2013 Share Posted August 30, 2013 woops, so ive been doing it wrong? dang it.. and i just mixed up some salt last night... haha Quote Link to comment Share on other sites More sharing options...
+KimP Posted September 7, 2013 Share Posted September 7, 2013 I was reading about this salt mixing thing and got to thinking. If alk and/or Ca and whatever else starts to precipitate out if it's mixed longer than 4 hours, would it just precipitate out in the tank if put in before 4 hours? How is blowing around in the tank different than blowing around in a trash can? 1 Quote Link to comment Share on other sites More sharing options...
bige Posted September 8, 2013 Share Posted September 8, 2013 That's a good question. Quote Link to comment Share on other sites More sharing options...
offroadodge Posted September 8, 2013 Share Posted September 8, 2013 I don't know what it has to do with the can other than lack of airiated oxygen that helps keep the element stable. "IN 7 YEARS OF REEFING AND USING Red Sea Coral Pro I HAVE ALWAYS 1)PUT WATER IN BARREL 2)PUT CORRECT AMOUNT OF SALT IN BARREL 3)HAND MIXED WATER MAKING LIKE A TORNADO IN THE BARREL TIL THE WATER IS CLEAR, usually 10-15 minutes or less. 4)THEN PUT NEW WATER IN TANK. The one time I tried to mix it with a powerhead in a trash can over night there was this brown SHIAT all over the inside of the barrel and pump. So that's why I DONT do overnight at all. Happy Reefing!!! 1 Quote Link to comment Share on other sites More sharing options...
