ClarkiiClown Posted April 3, 2005 Share Posted April 3, 2005 Ok- I want to set up a DIY kalk dose. Now I understand that the kalk is held in a container and only a certain amount can be saturated in the water so as long as you dont shake your kalk mix up you can overdose that way. Now my question in do I let this run all day to compensate for the evaporation in my tank? Do I run it at night only? Do I use the water from the kalk doser for my sole evap replacement? (half fresh RO and half kalk-RO? or some other percentage of the two?) Any other considerations that I need to be aware of? Anyone else have a working kalk doser on a 12dx? Link to comment
doncb Posted April 3, 2005 Share Posted April 3, 2005 You would only want to dose Kalk at night to keep from having a large ph change. Also you don't want to dose a lot at once. Right now I have a drip dose on my 24g DX. Drips about 1 drop /second. Dose 8oz of Kalk water each night. Do have a pump on order that I will set up on a timer. Top off w/ RO water in the daytime. Dose Kalk @ night. Link to comment
ClarkiiClown Posted April 3, 2005 Author Share Posted April 3, 2005 OK- I have about 4oz of evap a day so if I set mine to say, 1 drop every 3 or 4 seconds that might be a good place to start. Do you know how many milliters 1 drop per sec equals out to? Link to comment
ndfootball5489 Posted April 3, 2005 Share Posted April 3, 2005 Kalk is something that you have to be real careful with. And in such a small tank it wouldn't take much to mess something up. Link to comment

Do you know how many milliters 1 drop per sec equals out to? Math makes my brain hurt. If you have 4oz of evap in a 24hr period, I'd top off 2 oz during the day and drip 2oz Kalk at night. I would think this would keep SG & ph fairly steady. Or you could drip all 4oz (Kalk) at night. Wouldn't matter if it took 2 hrs or 4 IMO. One thing you will want to test for is ph and hardness dK (dH?). Throw the #'s in a spreadsheet and graph it along with how many ounces of Kalk you drip. See what the trend is & adjust. As to how many ml 1 drop /sec equals depends on the size of the drop. No, really. Drops are different sizes. Honest! Link to comment
ClarkiiClown Posted April 4, 2005 Author Share Posted April 4, 2005 Point taken on being careful. I am going to do this REALLY REALLY slow. Like an ounce of kalk water overnight to start with. I plan to check everything during the night too. Im going to have some water ready too incase I have to do an emergency water change. Thanks for the replies! Link to comment
