Duff0712 Posted October 12, 2015 Author Report Share Posted October 12, 2015 Dosed my 12g with the acid and alkaline buffer per seachems instructions and the results are interesting. I figured the alk/acid buffers wouldn't mess with GH so I could try to get a precise PH without compromising GH. I decided on using both alkaline and acid this time to try and get a target KH and PH, since they are supposed to work well together in getting a more precise solution. I might try experimenting with only alkaline buffer (or even baking soda as I've been suggested) in a bucket of RO and see if I can pinpoint what I need without adding acid. Testing before: PH: 6 or below KH:0 GH:9 TDS: 204 The app told me to dose 1tsp alkaline and .5tsp acid for 12gallons to get 7ph and 2KH from my current KH parameters. I probably should have said 10g of water, but oh well. SCIENCE!!?!?!? Testing 1hr after dose: PH: 7~ (dim light so I will recheck tomorrow) KH:4 (off my target by 2) GH:9 (makes sense this wouldn't change) TDS: 297 (increased by 93) The TDS jumped almost 100, which is quite significant. KH is a little off my target, but for Neos shouldn't matter too much. If PH is at 7 then that was a bullseye. I just dumped the buffers directly into the tank so I will test it again tomorrow after the buffers have had all night to mix and see if any parameter has dropped. I am also going to just move all my experiments to my Journal. Quote Link to comment Share on other sites More sharing options...
