SRC Member fnscasey Posted January 5, 2004 SRC Member Share Posted January 5, 2004 Like to find out how u guy dose kalkwasser so that the dKH & calcium level are balance ? If say, before we dose kalkwasser, we test the PH, dKH & the calcium level first. Results: PH8.3 dKH=8 Ca=320 So when we dose kalkwasser for top-up, how do we make sure that the dKH & ca level are in the acceptable level ? Do we need to test the dKH & ca level after each dosage of kalkwasser ? Are we suppose to dose kalkwasser in term of the top-up level or dose as our tank volume ? Is there any steps when dosing kalkwasser for top-up water level ? Quote Link to comment Share on other sites More sharing options...
lightningstrike Posted January 6, 2004 Share Posted January 6, 2004 use test kits to check. dose kalk by controlling flowrate by dripping.

SRC Member fnscasey Posted January 6, 2004 Author SRC Member Share Posted January 6, 2004 Taken from other forum which is quite beneficial to me. Had learnt so much from this guy, " skeletor " So i'll post it for those who wanna know more ! The amount of kalk dosed is based on the number/size of calcium consuming animals in your tank, not tank or top-off volume. This is something which differs from tank to tank so you will need to figure out what your tank requirements are. You want to get to a point where kalk is maintaining Ca/Alk levels, and not changing them. Do a baseline test, then dose for a week and test again... if you are not maintaining levels then up the kalk dosage, if they are climbing then lighten up on the amount of kalk. Kalk has a very high pH (around 12) so you must take care to add it slowly (dosing pump or drip feed), and not send your tank into pH shock. This is also a good reason to dose at night, as it will help keep the pH more stable.. Dose into a high flow area, or the intake for your skimmer. Top-off volume only becomes important when you are unable to get enough Kalk into the system to maintain Ca/Alk levels. When this becomes an issue you may need to look for ways to increase the amount of evap so you can add more. It will probably take a few weeks to sort out the dosing requirements exactly. sorry that I can't provied more specific advice, you didn't give us much information about your tank, how much you evap, how much you currently dose, WC schedule, Ca/Alk load etc, etc. Quote Link to comment Share on other sites More sharing options...
SRC Member Jun Hong Posted January 7, 2004 SRC Member Share Posted January 7, 2004 Is the Ca/Alk consumption rate always stays constant? I doubt so. Coral grow and new additional of coral will require us test and monitor the Ca/Alk consumption rate again and again. So tedious I wonder how often you guys test your water parameters?

Assillian Posted January 7, 2004 Share Posted January 7, 2004 How about using 2 type of additives like the Seachem Reef Calcium and Reef Builder/Carbonate? Does it work the same as Kalk? Quote Link to comment Share on other sites More sharing options...
SRC Member Jun Hong Posted January 7, 2004 SRC Member Share Posted January 7, 2004 Both of these additives serves the same purpose but they cost much more than kalk. So we only use them to boost the Cal/Alk to optimum value and use kalk to maintain Ca/Alk. Unlike kalk, Seachem Reef Calcium and Reef Builder/Carbonate won't affect the PH.
