wooz29 Posted February 1, 2006 Share Posted February 1, 2006 Currently I am cycling my tank and running the lights 12 on 12 off. My temp is staying between 78 & 80. My question is does this 2 degree fluctuation cause any problems? Also my salinity is at 1.021 for the past 4 days. Is 1.021 acceptable or should I raise it to 1.025? Thank you Link to comment

My temperature swings between 78 and 80 as well throughout the day, so I don't think it's an issue. Link to comment
wooz29 Posted February 1, 2006 Author Share Posted February 1, 2006 What's the best way to raise the salinity? Just dump a little salt in or mix it with a bit of r/o? Link to comment
drg0nzo1 Posted February 1, 2006 Share Posted February 1, 2006 DO NOT, dump salt directly into a tank ever, always mix it first. To raise salinity, add salt water Link to comment
Paladin Posted February 1, 2006 Share Posted February 1, 2006 I'd slowly raise it by mixing it with your top-off water. Link to comment
wooz29 Posted February 1, 2006 Author Share Posted February 1, 2006 DO NOT, dump salt directly into a tank ever, always mix it first. To raise salinity, add salt water Why would you not want to dump it directly in the tank while cycling? Link to comment
drg0nzo1 Posted February 1, 2006 Share Posted February 1, 2006 well if you are first setting it up its fine...i assume you have LR in the tank? If so, mix it first. And adding salt directly can result in you putting way to much in very easily. Link to comment
Maeda Posted February 1, 2006 Share Posted February 1, 2006 What I do once in a while is dissolve some in a small amount of water and then put it in my sump.... Link to comment
steelhealr Posted February 1, 2006 Share Posted February 1, 2006 First off..it's specific gravity....you are discussing specific gravity. Salinity is measured in percentage points and is a DIFFERENT PARAMETER. The 'proper' way to raise your specific gravity is to do your water changes with a slightly higher level s.g. Eg. if you are at 1.021, do your next 10% water change with 1.022. The other way to do it would be to let your s.g. drift slowly down one point and then topoff with the same s.g. SW. DONT DUMP SALT MIX INTO THE TANK UNLESS IT IS EMPTY and it is being prepped for LR and LS. SH Link to comment

steelhealr Posted February 2, 2006 Share Posted February 2, 2006 pet peeve...no problem.....welcome aboard and.....here's to Iowa. SH Link to comment
wooz29 Posted February 2, 2006 Author Share Posted February 2, 2006 On my refractometer, right side of scale there are percentages, is that for salinity? Link to comment
steelhealr Posted February 2, 2006 Share Posted February 2, 2006 Yes....salinity is the amount of salt dissolved in a fixed volume of water and is not dependent on temperature. Specific gravity is the density of salt in a unit of water and IS dependent on temperature, hence, why many refractometers are calibrated to be accurate within a varied set of temps.
