DaveSamsell Posted July 20, 2020 Share Posted July 20, 2020 Was tired of dumping the liquid test tubes. So, I constructed a personalized, DIY test stand. 1 2 Link to comment Share on other sites More sharing options...

Hi Daniel, It works by preventing the test tubes from tipping over, when filled with liquid. Each tube is fully removeable. My testing area stays much dryer, now. 😊 Link to comment Share on other sites More sharing options...
Daniel Posted July 20, 2020 Share Posted July 20, 2020 I get it now. Dave, you seem so hi-tech, I thought it automatically did the testing somehow and I just didn't understand it! I bet @Bill Smith is working on a solar powered automated system as we speak. 🙂 1 Link to comment Share on other sites More sharing options...
Sliceofnature Posted July 20, 2020 Share Posted July 20, 2020 Im super clumsy and have knocked over my test tubes on more than one occasion so i knew i needed something like this but i just hadnt taken the time to do it. When i saw your stand today i decided i was done putting it off so i went out and made one out of an off cut i had lying around. So thanks Dave, if you hadnt made yours i probably never wouldve actually made one for myself. 1 Link to comment Share on other sites More sharing options...

Am sure the stands will help the both of us. 👍 Link to comment Share on other sites More sharing options...
H.K.Luterman Posted July 21, 2020 Share Posted July 21, 2020 I had my hubby 3D print me a test tube stand at his work place because I too was tired of the test tubes falling over. Your solution is much nicer looking than mine. X3 1 Link to comment Share on other sites More sharing options...
Tre Posted July 21, 2020 Share Posted July 21, 2020 Can I get a drill bit size for API? I've always rigged weird temporary things....this is a must! Link to comment Share on other sites More sharing options...

I used multiple drill bits, leading up to 1/2" (since that was the largest bit I had available). I have some manual tools here and then used a hand reamer to widen the opening a little bit on mine, for ease of use. It's not an exact science, of course, but worked well with form, fit & functionality. 1 Link to comment Share on other sites More sharing options...
StephenP2003 Posted July 21, 2020 Share Posted July 21, 2020 I want to make a full tray that not only holds the test tubes but also the test solutions. I have one right now modified from a test tube holder I found on Amazon. I cut out the back half to accommodate the solution bottles. The tubes are color coded for each tank, as are my sample syringes. But I have more tanks, so need more room if I want to test them all at once. 3 Link to comment Share on other sites More sharing options...

I think that would be overkill for my 2 nano tanks tho... haha How many tanks do you have right now? Link to comment Share on other sites More sharing options...

I hardly ever test all tanks at once, and I normally just test nitrates. Link to comment Share on other sites More sharing options...

I usually only use the other tests if something seems off. Link to comment Share on other sites More sharing options...

I usually only use the other tests if something seems off. I tried that method a couple of times, but proved to be disadvantageous. Unknowingly, one of my tanks KH & PH was dropping, fairly quickly, with only moderate nitrate readings. It takes only a few minutes more of testing to see the full picture I suppose.
