Has anyone tried Clear as Crystal by Clear Pond? Main ingredients are
Laumontite Crystal & Calcium Aluminum Silicate. It is said to slowly
clear cloudy or dirty water and keep ponds clear for up to three months,
at which time you're supposed to replace the bags. It says remaining
crystals are safe for fish to eat.

My questions: Is it also safe for plants? And the biggie, does it work?

I saw it at PetSmart. Most of the information I've found through Google
is either from people selling the product or a bit too scientific for my
wee brain to wade through.

Hi Gabriella,
In my first season, I tried commercial methods to clear up my pond.
They worked: for a while and then you had to keep doing it. During
the second season, I started using water cress, water hyacinths, and
other plants to clear up the water (along with my bio/mech filter and
now a veggie filter) Since that time, I usually experience one really
good algae bloom during the early part of spring and after that, I am
the envy of my neighbors that have bonds. Water remains clear to
crystal clear through the end of the season (for us in Colorado
Springs that is around Thanksgiving). In short, yes, it probably
works. However I think you will be much happier in the long run by
working on the ecosystem of your pond. Finding that balance that
keeps the water clear for you.
Just my opinion. Hope it helps
Dale



I've been pretty much "natural" for over two years now. I do
periodically add koi clay & bacteria plus dechlorinator when I add
water, but I don't use algaecides and don't want to.

My 1500 gallon pond has one waterfall filter with a small settling pond
-- both filled with water hyacinth -- a 75 gallon Skippy filter that has
WH at the top so it is also a veggie filter, a small mechanical filter.
The pond itself is about 20 -30% covered with water hyacinth, water
lettuce, and parrots feather that are all still spreading.

I have had clear water from late November, when it cools down, to
mid-March when it starts seriously warming up here in southern Arizona.
Then the water starts getting murky due to the heat, the increased
bioload, etc. I haven't had pea soup this year, just some string and
blanket weed, which I tolerate in most spots. I don't mind slightly
murky water but would like to see more of my pond, which is why I was
considering the Clear as Crystal product which is billed as "all natural".

The blurb says "Clear as Crystal is a unique form of Laumontite Crystal,
Calcium Aluminum Silicate and when placed into pond water, produces
oxygen, balances pH, purifies water through an ion exchange process,
reducing toxic levels of ammonia, contains essential minerals that are
utilized by the fish to keep them healthy and their color bright and
will keep your pond clean and Clear as Crystal."

I'd still like to know if anyone has tried it or knows anything about it
and whether it would be safe for plants as well as fish and turtles.
