3rd Shrimp Setup

Hi every1,tis is mine 3rd Shrimp setup,
1st 2 setup failed....finally came up with this,

Currently Keeping sakuras only,
Temp : 28"C
Using HOF

Can i know the recommended Ph level and is aged water good
to use during top up and can i use Nutrafin branded Anti-Chlorine
for the aged water?

Thanks for viewing,comments are welcome
