The subject says it all really. I have a female Dalmation Mollie that has given birth in a 10g with 8.0 pH back to the 60g at 7.0 pH.

My plan is to do a 30% wc with 7.0 replacement water, wait awhile, then put her in a bucket with 1g of her water then drip another gallon of the 7.0 water from the 60, then pour the whole mess into the 60g.

Think she'll be ok? I know that Mollies pefer the hard, salty water, but the 60g is the only place she can go. The three Mollies were aggressive to the tankmates in the original 10g they came from. So far, the Mollies in the 60g seem to be doing fine.

An easy way to do this is with a large, sealable plastic bag. Place her in the bag with some water, about 1/2 full. Dump about 1/4 of the water out and replace it with your new water. After about an hour dump another 1/4 out and replace it with your new (7.0) water. Do this 2 or 3 more times and everything should be fine. Mollies can tolerate sudden changes in ph or hardnes much better than a lot of fishes.

Forget easy...do it right and drip acclimate the fish. Just as easy as any method and proven to be the best way.

Well, she's out of the 10g and back in the 60g and seems fine, thank goodness. What I wound up doing was repetitive wc's in the 10 until the pH got to 7.4 and then just scooped her up and into the 60 with the 7.0 pH. I wanted to get the pH of the 10 down to a more manageable level anyway. I took about 45 minutes between 20% wc's to allow her (and all the Mollie fry) to get used to it. I didn't count the number of wc's it took but it was a lot. I just finished and I started at the beginning of this post.

It looks kinda cool with about 50 little fry swimming around pecking on the numerous plants and algae I allowed to grow in that tank. I'm using finely ground flake food and dust sized dried brine shrimp as fry food.

I had setup that 10g as a rescue tank for any of the African Cichlids that might have needed it when all that chaos was going on. They have settled down and all seem healthy now. Now it's a fry tank.

Good morning Restart...

Glad everything worked out for you and your fish. You actually worried too much about the pH of your tanks. Most aquarium fish can tolerate water with a pH of between 5 and 9.

If you follow a good tank maintenance schedule which starts with a 25 to 30 percent water change every two weeks in tanks up to 30 Gs, (larger tanks require larger changes less often) you really don't need to be concerned with pH. The reason is regular water changes keep carbonates in the water. Its the carbonates that maintain a constant pH.

Good Memorial day to you BBradbury,

Yeah, I guess there is as much art as science in our hobby. Some friends told me fish are more sensitive to quick pH changes than tempreture changes. I finally felt that a .4 change (from one tank to another in seconds) would not harm them. So far, so good.
