crs water

[vanessa317]

i am getting crs tomorrow i have been told the water from the tap isnt good enough for there requirement's. i have been told watermill's or water from lfs. does anybody with experience have advice?

[fishman1]

tap water is fine as long as it is dechlorinated properly ask the person your buying from what their water conditions are and try to match that.

I just got into CRS about two months ago and all I use is tap. I have five berried shrimp so they aren't bothered by it at all.

[eklikewhoa]

When I had them I would mix 50/50... de-chlorinated tap and watermill water.

I use ozarka bottle water and ph is stable at 6.8 and i have a berried female with in a month

[eklikewhoa]

I don't think pH bothers the berry up part, it's the hatching and survival rate of shrimplets that the pH has a greater effect on.

i have seen parameters online for crs and im sure just like other things it is the "PERFECT CONDITIONS". what parameters have you found success with or are these pretty realistic. my tap water is about 8 ph and gh 150

well thats why i am using RO with them.and its only a 3g tankso the water is always stable. and its working for me. i jut have to see how the shrimplets will react to it in a couple of weeks.

I would keep the water slightly acidic.
My tapwater is 7.8 out of the tap. They get berried, but are very short lived and I almost never see any babies.
I injected CO2 to reduce the pH to 6.7 and their population just exploded. The older ones stopped dying and the babies survive till adulthood.

[R_sustaita]

i believe Ek had mention that indeed CO2 would drop the ph levels but the breeding would slow down because of the chemical inbalance that the co2 was making.

CO2 doesnt cause an imbalance as long as you buffer your water. If you try CO2 with RO water then your pH will plummet due to the carbon being scavenged. I just experimented with trying to keep neocaridina sp. in aged tap water (pH 7.8-8.0) and the colony is dying. i see no shrimplets surviving at all, as nacra reports. it was suggested to me that high TDS may be the problem as well so i am going back to a 2:1 ratio of watermill:aged tap and IAL until i get my RO setup installed. i would definately look into keeping the pH acidic with substrate, indian almond leaves, or alder cones if you dont want to use CO2. there are a good number of knowledgable shrimp people here, search for posts by armthehomeless, bikeguru, and texsun. there are others too, but i recall that these members have a number of forum posts on the subject.

i have at least 7 berried at the moment, they just got to breeding age, ph is 6.2 (using ro) substrate is brightwell rio escuro xf, gh is 4-5, kh is 0-1, no nitrites, nitrates, ammonia. Its only a 8-9 gallon tank, and so I do water top offs since its a rimless open top tank like once every other day of about half a gallon, and every 3-4 weeks i will let about a gallon evaporate, and then take out another half gallon and put back in 2ish gallons. I use fluval shrimp mineral supplement to get the RO tap water to a gh of 4-5, which seems to be the sweet spot.
