well the subject of water parameters is an ongoing argument or should we say an on going experiment for all of us and there seems to be no end in sight. but i recently came across an interesting theory and was wandering what all us ray keepers use as a main source of water. untreated "well". or treated "city" water. i know most people dont pay as much attention to where the water is coming from. but when major loss or stressed out rays come in to play you have to only wonder what really is the source? i recently came across a situation where a ray was CB in well water and a year later was brought into "city" water and from the get go was not the same ray. washed out colors. went from a really light base to a dark base, having trouble getting him to eat, not very active. and the same is true in a case of a pair of rays going up north from being rased on well to city water. both of which completely lost color. in both cases ALL other parameteres checked out. the only missing link is the "well" and "city" water.has anyone else experienced this? is it simply a case of not acclimating well? or does it have something to do with being used to certain hardness/gh/kh/salinity/alkalinity that has to do with there overall well being. to some this may sound like a bunch of mumbo jumbo but if some of you experienced keepers put some insight into rays you have either bought sold or traded. as well as rays that were imported. has anyone else ran into this issue? thanks in advance!
