I know on many sites they say the ideal pH for RCS (or neocaridina's in general) is between 6.5 and 8. However, I know many people here find they are breeding at pH's of 8.7. Has anyone ever tried more acidic pH's, like anything under 6.5? This is just out of curiosity at how well these little shrimps adapt.
i tried keeping some of my cherries in my bowl with my crystal shrimp back when i was converting the water slowly to soft, and acidic. after a while though the cherry shrimp (i think there were two left in there) just disappeared so i assumed they couldn't live well in very acidic water. the crystals are still doing good.
though i do hear of people keeping them in acidic water, i bet they don't do as well in something less than 6.5 like you said.
I think my bowl pH is a bit less than 6.5
I had bad experiance with RCS in my CRS tanks.I lost over 100 for a year in 6 tanks.PH is 6.4-6.6 I have one tank at work with PH 7-7.2.With killis,swordtails and neons.Water changes every 4 months.temp is 70-90F there are more than 200 RCS.
