Question about Water and CRS
I have a tank of CRS and have been using Albertson's Distilled water for top offs because my tap water has a high PH. I read on one of the shrimp blogs that people were using the RO water sold by Walmart for their shrimp tanks - so yesterday, I truck over to Walmart and buy a 5 gal. jug of their RO water intending on doing a water change.
Before doing so, I looked up online the name of the water, called PRIMO, and according to its water report, it contains 0.016ppm copper - yikes -
Is 0.016 ppm copper considered high enough to hurt the CRS? If so, I don't understand how people are using the PRIMO for their shrimp tanks. I contacted Seachem rep regarding whether Prime would remove the copper and he says it only detoxifies the copper temporaily.
So, my question - my tap water is out. Is the PRIMO water out too? And what can I use for water changes and top offs? It's a small 10 gal tank so purchasing water from the store is my best bet - but I don't know what to buy. Any advice will be greatly helpful. Thanks.
