As my place water is very alkaline ,7.8-8...and very low in Gh and Kh.
After aged the Ph remain the same.

May I know what is the Ph of the babies ranchu in ur place?.

As i reliased that after 2 days in green water my Ph will drop in2 6.2 .After water change the second days ,most of my goldfish always cover with slime while the ammonia raise in the critical level due to Ph crash.
To avoid the tragic happen again,i add some coral in the tanks as a buffer.

Can i do the same thing adding coral in these babies ranchu after i recieved from u?.thanks.
