I have been thinkinng of buying some of the jugs at the LFS and buying my water instead of doing changes/ top offs with tap water and conditioner. My question is should i buy the filtered water or the RO? There is only 2 cents difference in the price so i'm not concerened on the price just what is going to best for my fish. This is a 75G fresh water tank with Cichlids in it.

Reverse osmosis would be purer but really is unnessecairy, I would just stick to tap and a good conditioner like api stress coat. I use that in conjunction with api aquarium salt and I have never had a problem.
Unless for some reason your tap waters parameters are way off I wouldn't sweat it.
 
You will have to buy things to add to the R/O, or after a while you water in the tank will be to diluted and the osmosis will harm or kill the fish.
 
is there an issue w the tap water? RO might be harmful to the fish - what type of Cichlids are they? what is the ph of your tap?
 
where i live the ph is really basic (high) so thats great for africans but not so much for central-south americans. when we had the Geos we would do mostly RO and some tap but that was just to make the water softer for them
 
Definately do not use the RO for the cichlids unless you wish to add buffers to keep the PH stable. RO water is soft and susceptible to PH crashes. Most tap water is fairly hard and good for cichlids.
 
i have south american cichlids in the tank. I'm not sure what the ph is of straight tap water but we have really hard water with lots of chlorine in it so i was thinking with the filtered water it would be easier doing the water changes. and of course trying to provide the best enviroment for my fish

IDK unless you water is raw sewage I don't see whats wrong with tap water. My community seems to do fine in tap but I guess fine and doing well are in the eye of the beholder. I went out and bought an R/O+DI filter and the buffer to make it right for fish, I gave up on that after going though my second bottle of "R/O Right". I was still a young fish keeper then and Said forget it the fish just going to have to live with tap, I can afford this.


Now that I think about it I guess I am using filtered water now, since I have been running a drip system for the past 2 months. However prior to that it was just tap water and our friend PRIME.
