pH The Good, the Bad and the Ugly

Hi,

Can anyone answer this question that I have had in my brain for many years now...

In London, UK the tap water is about 8.2 pH. I used to work part-time in a tropical fish shop and apart from a filter to remove chlorine/chloramine... the tanks used just normal tap water. Mainly as most of the customers also used tap water with this high pH. What happens if I start using RO water with added minerals for keeping plants and tetras? Suddenly these poor fish will be going from a fish shop tank with a pH of 8.2 to my tank which will hopefully be between 6.8 and 7.2 pH.

I guess that is why African cichlids are so popluar in parts of the UK due to ideal hard, alkaline water from the tap.

Anyone got any advice on this?


Thanks,

JJ

you need adjust the fish with drip acclimation. Slowly drip water from your tank into a container with the fish.

I use feeder fish that I have to take from ~45F (7.2C) to 84F (28.8). I don't know what the other parameters of their original water is, but I have to assume its quite Hard. They went into originally hard water and now into very soft water. So, currently, I take the feeder fish from 45F to 84F, from unknown water to very soft water. It takes a few hours because of the temp extremes, but I've gotten pretty good at it.

My point is: Its not really about What you need to do--its much more about How you do it.

Drip-acclimation works well, many people use it and I have gone that route for some time. However, I currently just start them out in ~1g of their original water and add ~1g of tank water, wait 30 minutes and add another ~1g of tank water. I repeat that until the 5g bucket is full and then empty it down to ~1g and start over. After about 3hrs of this--they are usually ready to go into the feeding tanks and holding tank. It used to be a 36hr process with major loses!

Taking fish from Hard to Soft water really isn't difficult. Just think through whatever process you choose. Time is on Your side, and Bigger bags with more water is helpful also---gotta keep an eye on ammonia buildup! The more Original water that You have--the more tank water You can initially mix with it when you get home. The more water involved---the less risk of Ammonia build up.

HTH
