CornAndCrawlers Posted April 20, 2022 Share Posted April 20, 2022 Background of experiment: I have some cherry shrimp in a planted tank. I hear calcium is good for shrimp and magnesium and potassium are good for plants and that these elements can be observed by measuring GH. Problem: How can I add calcium, magnesium and potassium to my water? Hypothesis: If I add a multi-vitamin to my water than it will add these vitamins to my water and I can measure this change by checking GH. Dependent variable: normal tap water Independent variable: water with a vitamin Independent variable 2: water with a crushed vitamin Results: After 24 hours, my GH did not increase from this multi-vitamin. Instead, my PH increased from 7.0 to 8.5 and my KH increase from 40 to 180. Link to comment Share on other sites More sharing options...
Scapexghost Posted April 20, 2022 Share Posted April 20, 2022 The normal tap water is the control not the independant variable. The independant variable is the amount of vitamin and the dependant variable is the gH. Link to comment Share on other sites More sharing options...
CornAndCrawlers Posted April 20, 2022 Author Share Posted April 20, 2022 Hah, thank you! In addition to being new to fish keeping, im also new to the scientific method 😛 Doing an experiment was fun though, I plan on doing more and hopefully I will label the terms correctly next time. 1 Link to comment Share on other sites More sharing options...
ccurtis Posted October 23, 2022 Share Posted October 23, 2022 Interesting experiment, I would not have expected the ph to rise so dramatically. Link to comment Share on other sites More sharing options...
Schuyler Posted November 8, 2022 Share Posted November 8, 2022 I bet it's designed to break down in stomach acid. I wonder if you added an acid in the if it would release more of the minerals. Then again it's probably cheaper/easier to just get the wonder shell or whatever Link to comment Share on other sites More sharing options...
Flumpweesel Posted November 12, 2022 Share Posted November 12, 2022 I just tried something like this in very advised fashion. Popped a calcium tablet in the outflow of the filter in my shrimp tank, I didn't expect it to break down very quickly but after about an hour it was mush and the tank was cloudy did a water change (25%) and cleaned out the filter. My shrimp have been very active since and quite happy tested my water and the only change is the GH which is now off the chart. I'm keeping a tight eye on things but I think I got away with it, might take a more careful approach if I decide to do it again. Link to comment Share on other sites More sharing options...
