DanS Posted March 2, 2022 Share Posted March 2, 2022 I'm starting to use RODI water for my tanks, with some softer water fish and neocaridina shrimp. So far I have been mixing RODI with my tap to achieve the desired parameters. I want to move away from the variables that come with tap water and just use RO with a remineralizer. So far it seems most are just GH and trace mineral boosters, and the only one I see that boosts KH as well is salty shrimp GH/KH+. The salty shrimp seems expensive and I would probably go through it quickly. Any other alternatives out there for GH/KH remineralizer? Or what are your experiences with remineralizers?

Jimmy Posted March 2, 2022 Share Posted March 2, 2022 Not sure if this helps but I use nilocg GH booster. I have soft water, I just aim for a specific tds and it works for me. 1 Link to comment Share on other sites More sharing options...
Minanora Posted March 2, 2022 Share Posted March 2, 2022 Welcome to the forum! I use the Salty Shrimp GH/KH for my neocaridina shrimp. I have them in a 5.5G tank, I change about 50% of their water once every month. I have a tote from smart & final that measures to 10L. I use one scoop of SS GH/KH in there. Works great for me. I recently reduced my water change volume to just over 8L and add the same amount of SS. I'm gradually up-ing their hardness and PH to match my local water parameters. I recommend the salty shrimp stuff just because of the ease. I'm more likely to do things if they're easy. Brightwell also makes a liquid GH/KH product but I wasn't able to purchase it when i got the salty shrimp so that's what I got. 😃 1 Link to comment Share on other sites More sharing options...
DanS Posted March 3, 2022 Author Share Posted March 3, 2022 Thanks. I'll look at the brightwell. On 3/2/2022 at 3:21 PM, Minanora said: Welcome to the forum!

ScottieB Posted March 3, 2022 Share Posted March 3, 2022 There’s also Seachem Equilibrium, like the brightwell product it’s designed to be added to RO water. 1 Link to comment Share on other sites More sharing options...
Mmiller2001 Posted March 3, 2022 Share Posted March 3, 2022 Just get MgSO4 and CaSO4. You will use those two to build GH. For KH, you can use several different things. If you keep plants, I would use potassium carbonate (K2CO3). https://greenleafaquariums.com/products/magnesium-sulfate-mgso4-1lb-bag.html https://greenleafaquariums.com/products/calcium-sulfate-caso4-1lb-bag.html CellarScience - AD640LB Potassium Carbonate (lb) https://www.amazon.com/dp/B074D9BXRT/ref=cm_sw_r_apan_glt_i_DEK26WEGVH2149NAKHPD 1 Link to comment Share on other sites More sharing options...

Yes but I believe it only raises GH not KH. On 3/3/2022 at 1:41 AM, Mmiller2001 said: Just get MgSO4 and CaSO4. You will use those two to build GH. For KH, you can use several different things.

That's definitely a good option and makes it easy to control parameters. I'll have to look into the dosing calculations. Link to comment Share on other sites More sharing options...

You are right, Equilibrium only has K, Ca, Mg, Fe and Mn - which is GH, I missed your comments in the OP. I suppose baking soda could be something to only raise KH? One Teaspoon of Baking Soda in 50 liters raises KH by 4 dH. (Source: https://users.cs.duke.edu/~narten/faq/chemistry.html) Link to comment Share on other sites More sharing options...
DanS Posted March 10, 2022 Author Share Posted March 10, 2022 Thank you for the help everyone. I decided to go with the GH/KH+ from salty shrimp. Link to comment Share on other sites More sharing options...
