Switching to RO Water...how?

[michellev512]

I'm trying to lower my PH of 7.4 so I was told to do water changes with RO but I'm nervous about shocking the fish...
For a 75 gallon if I change out 30 gallons each week. How much RO to tap should I do?

You can gradually increase amount.

1st PWC do 1/4RO/3/4 tap
2nd week do 1/2 RO and 1/2 tap.

Test and see where your PH is at.

Are you trying to breed fish ?
Most aquarium fish will adapt to a higher PH. 7.4ph is not high.

What kind of fish and why do you need to lower PH ?

I used Distilled in my small tanks. About 1/2 DI /1/2tap. But that is for breeding fussy Shrimp. Regular tap worked for my other fish.

I keep sa and ca's in 8.2. as coursair said unless you are trying to breed or super sensitive fish I wouldn't hassle with it.

Apistogramma. Not trying to breed. Just want them to be healthy

I eventually wanted to get a pair of GBR but I think my water is too hard and ph is too high...
