SoCal suits me perfectly! Let's set up a date.
Meanwhile, just some quick data, in case anyone happens to be interested.
A lot of people seem to be concerned about how cement/grout effects water hardness. In this tank both the rock work and woodwork are grout.
They cured for a good couple of months before setting the tank up with flora and fauna.
I made a long overdue water change to this tank today. Changed about 70 % after three weeks of negligence.
Before wc:
pH 7,8
kH 5 dKH
gH
7dGH
After:
pH 7,5
kH 3dKH
gH 5 dKH
Tap water around here is buffered to stay mildly alkaline and pH is usually at high 7 or
even 8.
I see a tendency of the effect cement has on the water chemistry reducing with time.
This tank's only been in action for a few months.
My conclusion:
Not overly dramatic, to my eye. I'm not worried, at all.
Still, I wouldn't say cement is totally safe when used in aquarium deco.
Thanks for looking.
