Default put in new flourite, no pearling, kH dropped.

Finally I have totally replaced all my gravel to Flourite in my aquarium. It
was a PITA to clean, but it's done. That was finished friday night, it's now
Sunday afternoon and it's looking pretty clear so that's great. Except for a
few things...:

1. I've got no pearling on my leaves (maybe after transplanting all the
plants it takes a few days for them to start "growing" again) My C02 has
been running for about 11 days...21ppm should still produce pearling...

2. My kH levels have dropped from 10 to 9. (does this have anything to do
with the addition of the flourite?--I thought it would increase hardness??)
I had assumed that kH never fluctuated once you used water from the same
source all the time.

3. kH levels have dropped to 9 therefore my C02 has also dropped to about
21ppm (my pH is staying the same at 7.1) I thought I could just measure pH
levels for C02 but now it seems I've lost another constant in my
calculations

Any opinions?

Dave. THANX

The best I've ever managed is about 13ppm, so my experience doesn't
really apply to your question. That said, I've only seen any pearling
once. And in that case it was actually just one particular plant that
was producing a bubble stream.

Interestingly, if I shone a flashlight beam at the plant (in addition
to my normal 3 wpg lighting), the rate of the bubbling would instantly
speed up dramatically.

Biology in action. Very cool.

My kH fluctuates from 13 to 15.5 ppm. Have you checked that the kH of
your source has remained constant?

I rather doubt that the Flourite is the cause of any fluctuation, as
it's pretty inert.

How much light do you have?
2wpg in a 15 gallon wide...pretty plenty I think.

Anyway, I wouldn't worry about pearling. Your plants can be growing well

even
without it.

I've been getting pearling for the entire time (over 3 weeks) that I have
had C02 running...so it was a bit alarming to see it totally disapear.

Wrong. KH naturally drops in a tank. The more stuff you have rotting in

the
tank, the faster the KH drops. I have to change 30% of my water every

week to
keep the KH up in my 29 gallon tank. It's a bit overstocked. The shrimp,
platies, and snails keep breeding....

It's good I know about this..thanx. Yeah I'm starting a regime that
incorporates 50% water changes every week since I'm doing double doses a
week of traces and PMDD. btw, screw the legalities, send me some of your
snail babies! LOL I'm getting desparate...but I am trying to get the
plants to grow good...this will get rid of the algae. Hopefully my new
regime with PMDD will help with this.

Dave.

I bet you're right about the plants needing to adjust to their new substrate
before they start growing again...be patient and you might see more pearling
yet.
