Vexus Posted July 9, 2022 Share Posted July 9, 2022 So, I started testing my PH and KH and got some results that I'm unsure about. Using the API GH & KH liquid test kit, 1 drop = 17.9 ppm, my KH came out at a 4-5 (71.6-89.5 ppm) my goal is 2-5 so I'm good with that but my GH is what concerns me. My GH came out at 18-20 (322.2-358 ppm) WAY OFF from the 6-8 I want it at. I live in Las Vegas Nevada, so I understand the water here is super hard, but I do my water changes with RO water from my LFS. So, wouldn't the GH be lower? There are times ill use treated tap water when I need a couple more gallons when I run out of RO but not often and I assume not enough to make that big of a difference. I tested multiple times; the first GH test was 13 (232.7 ppm) and the tests after that came out to 18-20. If it helps here are my other tank details.... 36 Gal bowfront Planted pH 6.8-7.0 GH 18-20 KH 4-5 TDS N/A (don't currently have a monitor for this) Temp 74-76 F 3-4 squirts of easy green every 1-2 weeks And a few root tabs once a month at most My water changes are about 10 gallons give or take a few every 1-2 weeks Any help on what I can do to fix this is greatly appreciated.

Tommy Vercetti Posted July 9, 2022 Share Posted July 9, 2022 (edited) I also live in Las Vegas. My tank is GH 21 and KH 9. I use tap water. Ph is at 7.2 before the co2 turns on. Edited July 9, 2022 by Tommy Vercetti Link to comment Share on other sites More sharing options...
Patrick_G Posted July 9, 2022 Share Posted July 9, 2022 @Vexus, did you originally fill the tank with tap water? Maybe you haven’t done enough water changes to drop the GH to your target range. Link to comment Share on other sites More sharing options...
Vexus Posted July 9, 2022 Author Share Posted July 9, 2022 I recently moved so the water was originally 15 gal RO 15 gallon cycled and the rest tap best estimate. And I never really thought to test the RO Link to comment Share on other sites More sharing options...

Very similar water to us slightly west as well. On 7/9/2022 at 2:09 PM, Vexus said: My GH came out at 18-20 (322.2-358 ppm) WAY OFF from the 6-8 I want it at. Question, why do you need it at 6-8?

I will not pretend to be a shrimp expert but I do know neos can handle a much wider GH range than others. I have heard of people breeding them in high GH. That said, it typically is dependant on what the person breeding them keeps them at. Link to comment Share on other sites More sharing options...
Vexus Posted July 10, 2022 Author Share Posted July 10, 2022 Neos are what I’m wanting to get, most people on YouTube normally give similar ranges on water conditions so I was under the impression that’s what I needed to aim for. Link to comment Share on other sites More sharing options...

Amanos in my tank don't mind it one bit! Edited July 10, 2022 by nabokovfan87 spelling scientific names! Link to comment Share on other sites More sharing options...
