pH Status

Well, the pH yesterday and today drop further without any "task" carried out. At the moment it's around 6.57, this morning it was around 6.8.

Hopefully it can maintains at 6.5-7 which is ideal for Kelesa. If it drops too much, I will need to put in 1 KG of coral chips to buffer it a bit.

Might change some japanese mats for ceramic rings these days, stay tune!

Here's another photo I just took:
