My tap water has a reading of 60-70 tds, gh is 4 and kh is 1. So do I need to remineralize it to use it for Crs and CBS shrimps? Or do I use us straight away?

@Josh16622, you have excellent tap water for Caridina shrimp (CRS or CBS). Where do you live? That water is very close to rain water. Theoretically, you don't need to much to it if you acclimatise the shrimp to the water before adding it into a cycled tank. You can also increase it a bit to 100 TDS, doesn't matter what the corresponding GH and KH is. You would increase the TDS with Calcium and Magnesium sulphate which does not increase pH or KH. Premixed products like Salty Shrimp GH+ is what you would buy. But having said that, they shrimp will do well in you tap water. Just remember to dechlorinate it first. If anyone else has any thoughts on the subject, please chime in.

Well, I've got all the supplies for my breeder tanks. Now just working on rearranging, get my RO machine fixed and it'll be hurry up and cycle. I don't have any heaters and don't want to buy any so hopefully seeding the new tanks with mulm and filter cleanings will speed things up significantly. Think I'm going to buy a bottle of bacteria too, and am overstocking the main tank with cholla and whatnot to transfer. Question- Should I cycle with 50:50 tap:RO, or would straight tap be ok? My spring water is very base and hard. I've seen that my pH should stay above 7 while cycling. I'm wondering if I can't cycle with my spring water, ph 8+, I'm not sure about gh/kh(could/should test) but the waters usually 300+ tds from the well, and very iron rich. Ofc once cycled I'd change 90%+ water to hit the shrimp parameters. Before I leave, I found another couple of very fun morphs. They are red zebras with a uniform and complete black undertone that results in a maroon tone darker than Wine Reds. The one pictured has such fantastic stripes!

Do I need to continue adding ammoni?

Hi, eheim substrat pro its not a substrate but is a media to the filter https://eheim.com/en_GB/aquatics/filter-media/biological/substratpro/substratpro-180g but this media is very alkaline and raised my PH. now with new media neo media soft the ph is lower again. I dont use the double of the excel because im afraid too i use an half of the recomended. Thanks
