Today's Pond Q&A
In this issue:
- Dreaded String Algae
- Central Florida Koi Show
Hi - I was reading your newsletter, thanks for sending it out.
We have a 6000 cement gallon pond (which I think if we would ever
move and do another pond we would not do a cement) and we have
trouble with green and brown water also and after a couple of
years of doing the lava rock filter we did change to the aquabead
filter system that works for a 10,000 gallon.
We still have much trouble with string algae and other algaes. I
noticed that the carbon is suppose to remove the brown. We have
d in a UV light because it is expensive and they say that it will
not work on string algae. The part about Nitrobacter is that
available to buy. I am thinking that there are little pin holes
in the cement and just lots of food for string algae to grow on.
We do salt our pond but it comes right back.
The fish love swimming around in it, but I am concerned about the
oxygen level. We can harvest a 5 gallon buck now in about 2
weeks and when it is hotter more often. Plus we do have healthy
fish 5 are 6 years old (4e and 1 M) 4 are 4 years old (1f and 3m)
and then our spawn of 2003 about 40.
All the rambling and I guess my question is do you have any ideas
for string algae?
Yes, it's that time of year again - when the weather starts to
warm up and the dreaded string algae starts to re-appear after
This is mostly because of all the built up extra organics in the
pond from the winter 'break' have been slowly decaying and are
now an excellent food source for string algae!
It's true that UV's will not help with string algae (only green
water), and you are correct that cement is more difficult to rid
of string algae because of the porous nature of it's surface. It
gives the string algae a better 'foothold' which is tough to
The short answer is -- try some Algae Fix! It's about the *only*
thing I've found to work and is safe for fish if used correctly.
I use it, and feel safe using it with my imported KOI -- but it
can cause a drop in dissolved oxygen levels of the water SO MAKE
SURE TO AERATE WELL WHEN USING ALGAE FIX. Just run your
waterfall 24/7 when using it, and you should be fine.
Generally, 2-3 treatments of algae fix will do the trick (spaced
3 days apart as per the instructions).

Orlando Koi Show << Out of Office Announcement >>
This is just to let everyone know that we will be out of the
office from this Friday March 11th through Sunday March 13th.
We are exhibiting at the Central Florida Koi Show in Orlando this
We'll be teaming up with Gary Cryer of Aquabead to 'teach these
old timers' a thing or two about pond filtration...
For those of you who may be in the area, or would just to check
out the show's website, you can do so here:
This is a BIG koi show, so definitely try to make it by.
We'll be taking lots of pictures (and more videos) to share with
you when we get back next week, so look forward to that.
As always, Happy Pondkeeping!
