EVoyager31 Posted January 19, 2022 Share Posted January 19, 2022 Anyone use wondershells for calcium and water hardness? I have very soft water and I want to keep my mystery snails healthy and happy in my tank. I always see different sites and forums mention wonder shells. anyone have any positive experience? How many large or small wonder shells do I need for a 75g tank? Link to comment Share on other sites More sharing options...
Beardedbillygoat1975 Posted January 19, 2022 Share Posted January 19, 2022 I think you would be better off with some crushed coral in a 75 g it would be too difficult. I used wondershells in a 15 g planted shrimp and snail tank. Link to comment Share on other sites More sharing options...
Patrick_G Posted January 19, 2022 Share Posted January 19, 2022 If you use them be sure to follow the directions on the Aquarium Co-op website. I used the directions on the package and it spiked my GH way more than expected. I agree with @Beardedbillygoat1975, over time I’ve found crushed coral to be the best way for me to mineralize my water. Link to comment Share on other sites More sharing options...
laritheloud Posted January 19, 2022 Share Posted January 19, 2022 I use Wondershells to remineralize my low-GH high-KH water and it works well for me. I use 1 of the smallest size shells in my 10 gallon tanks at a time (replace once fully dissolved and after a water change), 1 of the medium sized shells in my 29 gallon tank, and 1 of the large sized shells in my 55 gallon. This has consistently maintained a GH of around 7 to 8 in my tanks. Start conservatively and see what it does for your water and DO NOT follow the package instructions. 1 Link to comment Share on other sites More sharing options...

Are there other ways to have it in the tank where it wont be seen? Link to comment Share on other sites More sharing options...

Levi_Aquatics Posted January 19, 2022 Share Posted January 19, 2022 I always use them in my 10 gal shrimp and snail tank and it works well. I put one small one in and then wait until it completely dissolves before adding another one. 1 Link to comment Share on other sites More sharing options...

ChefConfit Posted January 19, 2022 Share Posted January 19, 2022 I have used wondershell before in various sized tanks. As others have stated it dissolves relatively quickly and spikes gh. In larger tanks you are probably better of with crushed coral long term. Using the wondershell to get the gh up initially and adding crushed coral to maintain it long term is probably a solid plan. I use crushed coral in a media bag in my filter as well as mixed into my substrate. 1 Link to comment Share on other sites More sharing options...
