Ira Posted December 4, 2005 Report Share Posted December 4, 2005 Anyone that uses ASW tested their salt lately? I tested mine a few days ago. Crystal Sea KH 9.3 (Good) Calcium 390 (Low) Magnesium 1050 (WAY low!) That's all I tested. I've got some chemicals on the way to fix those though. Going to be like 400grams of magnesium I'll have to add each water change! Quote Link to comment Share on other sites More sharing options...
lduncan Posted December 4, 2005 Report Share Posted December 4, 2005 A lot of ASW is low in magnesium. Red Sea it one that comes to mind. Instant Ocean is often low (lower that I prefer) in alk and calcium. Calcium levels of 390 aren't particularly bad. Around 350 is apparently the limit to where it becomes the limiting factor in calcification (alk usually is). I stick with either Red Sea, or Instant Ocean. I'd use IO if I could get it in 40kg boxes for the same price as Red Sea. Layton Quote Link to comment Share on other sites More sharing options...

cracker Posted December 4, 2005 Report Share Posted December 4, 2005 You wont need anywhere near that much Ira. It goes a long way especially in a 400 litre tank. Will last you ages. Quote Link to comment Share on other sites More sharing options...
Ira Posted December 4, 2005 Author Report Share Posted December 4, 2005 I'm just going by the numbers on http://home.comcast.net/~jdieck1/chem_calc3.html Magnesium Chloride anhydrous would be 200g ish to increase 150 liters by 200ppm.

Ira Posted December 4, 2005 Author Report Share Posted December 4, 2005 Mg chloride is cheap as soap powder so who cares try APS chemicals That's where I got my last batch. Mag Chlor Hexahydrate. Was $30 for 500 grams if I remember right. Quote Link to comment Share on other sites More sharing options...
Pies Posted December 4, 2005 Report Share Posted December 4, 2005 I paid about $105 for 5kg from APS. Don't bother any more, my reactor is loaded. Pie Quote Link to comment Share on other sites More sharing options...
