victoly Posted February 18, 2015 Author Share Posted February 18, 2015 My guess right now is that I just have concentrated alk solution. Link to comment Share on other sites More sharing options...
FarmerTy Posted February 18, 2015 Share Posted February 18, 2015 Does it have the ability to evaporate much? I just find it odd that it was more of a jump in alk and not a progressive increase if the alk solution became more concentrated. Maybe I misunderstood you though.

victoly Posted February 18, 2015 Author Share Posted February 18, 2015 No, no ability to evaporate. I was just thinking that maybe it wasn't mixed enough and kind of settled into a hyperconcentrated layer, although your point is well taken. You would think that there would be a gradual increase instead of a quantum leap at the end of the container. I'll turn my dosing back on tomorrow once it gets back down where i like it and see how a days worth of dosing affects the tank. Link to comment Share on other sites More sharing options...
Reburn Posted February 18, 2015 Share Posted February 18, 2015 I just bought a Hanna alk. When I test with the Salifert I turn the solution pink. Not just purpley blue. When I compared my hanna readings vs my salifert readings they were within 0.2 DKH from each other. I haven't checked against Ty's reference solution yet.

victoly Posted February 18, 2015 Author Share Posted February 18, 2015 I've had them compare close, and I've had them pretty far off. It's inconsistent in comparison. Alk isn't a finite parameter like pH or temperature. There are a several speciations of "alk" involved, and in marine analysis, it's even more complicated because of other interdependent parameters. It'd be great if we could just use the little color changing bulbs like you can use in FW aquaria to indicate CO2. Link to comment Share on other sites More sharing options...
Richard L Posted February 18, 2015 Share Posted February 18, 2015 I like the hyperconcentrated layer theory. I know with BRS's soda ash they recommend stirring while slowly adding it to the water indicating it is difficult for it to go into solution. If only you had experience working with chemicals.

victoly Posted February 18, 2015 Author Share Posted February 18, 2015 Mine was liquid B-ionic because I'm fancy, so it shouldn't be an issue. It's just the only theory I have that makes even a little sense. That or the electronics in my doser freaked out. Link to comment Share on other sites More sharing options...

Reburn Posted February 18, 2015 Share Posted February 18, 2015 The c02 drop checkers aren't that accurate either. They take hours to respond and the solution needs to be changed periodically. While they work at a glace there isn't a good way to measure co2 concentrations in FW on a hobbiest level. Your fish are a more accurate checker. If they are at the surface gasping for air your dosing too much c02 and need to off gas immediately. It's no different then a dosing pump or CaRx. The biggest mistake you can do is set them and walk away for hours. They need constant checking over a day or two to get a needle valve and bubble rate dialed in.

victoly Posted February 18, 2015 Author Share Posted February 18, 2015 Agreed, its just nice to have a "constantly on" indicator of a critical parameter. Link to comment Share on other sites More sharing options...
Reburn Posted February 18, 2015 Share Posted February 18, 2015 Agreed. Some people try and measure co2 saturation by montoring ph as a drop of 1 ph in a cup of just water would be equal to 30ppm of co2. The problem is that driftwood, gravel, stone, KH/GH and numerous other things can affect your PH as well. Link to comment Share on other sites More sharing options...

ckyuv Posted February 19, 2015 Share Posted February 19, 2015 So you guys lost me, does the Hannah alk meter just give you a number you have to put into a math problem? The api test kit works pretty well it turns from blue to yellow in the matter of a drop. Just Gota be able to count to 8... Link to comment Share on other sites More sharing options...
jolt Posted February 19, 2015 Share Posted February 19, 2015 Yes, it gives a ppm number which can be converted to dkH using a formula (X ppm * 0.056dkH/ppm), and if you know the correction factor you scale it by that number. Using Ty's calibration standard we determined my correction factor to be 1.01 Link to comment Share on other sites More sharing options...
victoly Posted February 19, 2015 Author Share Posted February 19, 2015 The only problem with using hanna's standard is that it still uses their analytical method, which may have some bias. I don't know that we could ever find a "true" value short of finding a chemist way above my pay grade, I just want to sit down in the middle of NSW range and try to keep it steady. If it's off by 10 ppm, it doesnt matter that much as long as it's consistent. Link to comment Share on other sites More sharing options...
FarmerTy Posted February 19, 2015 Share Posted February 19, 2015 You make a good point on the standard. Hopefully somewhere I am within NSW range... I know it's been steady so that's good at least. Link to comment Share on other sites More sharing options...
