View Full Version : Carloskoi - Trickle Tower / Waterfall Wall

06-23-2004, 08:11 PM
I wanted to build a trickle tower with the crate idea but my wife wasn't too happy about that.

so i came up with an idea to hide the crates behind a waterfall wall.

we started to build it today.

let me decribe my filtration system i have now.

gravity fed bottom drains to a vortex, then gravity to chamber with Matala mats. from there pumped through two large bead filters with two pumps and back to pond.

one other bead filter on separate pump goes to the round tank on back corner of pond which has water trickle over and gravity back to the pond.

over the settling chamber are two 50 gallon drums with small red lava rock fed by a sump pump. although these have only been online for a few weeks they are starting to slow down and clog some. the lava rock and trickle tower Matala media will be used in the crates.

i will hook the two bead filters up in series to free up a pump to use for the new TT. this pump can draw from the bottom drains through the vortex, bypass the vortex, draw from the Savio skimmer or all three at the same time.

i will be using about 70 crates with Matala mats and red lava rock in them with >7,000 gph over them. they will be five high and fifteen long.

where is the best place to pull this water from?

any comments or ideas are welcome.

the vortex and matala chamber, with the lava rock that is going away

the foundation

framed and poured for spillway

it's not just a koi pond. daughter and friends. the fish went to the 9 foot end while the kids were in the pond/pool.

to continue in my original thread.

it took 5 weeks to quit foaming so much and the water to clear.

08-21-2004, 06:59 PM
75 of these went in

08-21-2004, 07:01 PM
foamed like crazy for weeks

pretty foaming

the water continues to clear. i'm surprised it took 6 weeks to quit foaming. i have been doing water changes 10-15% per week.

i am feeding about 2 pounds per day to the 50 or so fish.

had a small nitrite spike, <.25 after taking the bead filters off line. it only lasted a couple of days, never ammonia.

even three months later still producing a lot of foam. this is overnight production.

the fish have never seemed happier.

Refresh us on what kind of mechanical filtration you have? While the TT may be producing foam through agitation, the mechanical end may be making the DOC's. It's early, hope that makes sense.


09-17-2004, 09:16 AM
my mechanical is a 1600 gallon vortex, 9 feet deep with 125 brushes in the top. i also have a large bead filter that i am not running now. trying to save some electrical $$$. this is flushed once a week.


09-17-2004, 09:28 AM
How do you feel the brushes are working in that application? Do they create a solid wall that the water must pass through before it exits the vortex?

I'm actually hoping to see your setup in person :) Tom talked about spending the better part of a day with you in October so we could see your tower etc. and then go on to Eastern Nishikigoi (and other places?) to look at the new shipments of two year olds :)

come on by. we are having the So Cal Koi Club monthly meeting at the house Oct. 10th. not sure what time the meeting starts. all are welcome.

to answer your question, they do trap much of the solids, although there are always fines in the pond. i am still evaluating how they system is working with out the bead filter. i will probably turn on the bead filter before the meeting to give some final filtration of the fines. i don't need it for any thing other than mechanical.

overall i am very happy with the way things are working now that i added the trickle tower/waterfall. it sounds great too.

i kind of wish i had spent more money and gone Tom's route with the Nexus but would have needed at least three or four and more $$$.

thank you.

all the water is pumped to the top of the TT with a 3/4 hp WLim pump and the water T's off at the far end at the top of the TT with a valve to the TT portion and another valve to the waterfall.

i need to get some better pictures of this area.
