i was thinking of having plexi anchors glued to the bottom of my
tank, with holes drilled in them to run pipe through to hold the pipe down then run my pipes up from there. are u just useing the rock on top of the pipe to hold it at the base of the structure?
thanks marc...killer tank

Simply exquisite! Best application of planning and amazing ideas I have ever seen thus far! I definitely commend you on your ideas and the application of them! The system amazing!

Amazing work! I've been debating whether or not to go plywood/fiberglass/starfire on my future 500+ gallon tank. I'm now officially convinced.

after seeing what you did im considering building my dream tank (96" x 32"x 24 h - 320 g)
in thinkung that can u show any detailed construction pics especialy of the sides and corners
also i was thinking ;
instead of spending a fourtune on fiber glass resin and epoxy paint
why not seal the wood w a few coats of sealer then contact cement a layer of pink foam then use a pool or pond liner contact cemented to the foam (doubled up of course )
that should seal it water tight

A little update..with a big skimmer

Hi all,
Just wanted to update you all again,
I have had abit of a problem keeping up with algea for some reason latley, so i was spurred into this next project.
( and the reason i havent showed too many tank pics latley..lol.)
Heres a bit of an unconventional skimmer build project that ive been working on for the last few weeks.
Its an dual Dart GG wheel and epoxy/fiberglass skimmer, built using a mould.
I started measuring to determine how big i could make it but still be 100% raw overflow fed, still get good flow through it, and be small enouph to fit in the foot print of my fishroom space that i had.
It ended up with a diam of 24" and a total of 70" tall.
the main body is aprox 105 gal.
Next step was a crash course in mould making.
Using MDF and arborite i made a half mould (is that how you spell it? )
Arborite being placed..
Waxing the mould...

Fiberglass layup..with the backside done first for the sake of practice.
On the front i wanted to be able to see, so i can learn abit from the impellar designs and view bubble size, and to have flat walls for bulkhead mounting.
I wanted the windows to be seated for strength aswell.
So i fit the front half of the mould with the needed shapes, and coated with wax again.
And glassed...
Out of the mould...
Halves tacked together...

Making the cup was next...routing pvc sheet for a flexed lexan exterior.
complete...
Determining (guessing) appropriate neck size & finish sanding for exterior.
Making the keyhole flange,
Onto plumbing drains, 10" input chamber,feeds and outputs and leak testing...
Impellar and venturi testing...
This one nice fine bubbles, but didnt seem to be enouph.
The end result was pulling out the entire venturi`s and pumping in 100 LPM of air on a pump.
i didnt have a flow meter to really get accurate, but it seemes it will accept about another 50 LPM before becoming unstable or burping.
Possibly more impellar designs should allow me to get 200LPM in there i hoped.

Removed some of the vanes and covered in GG..this one overheated the pump, causing it to shut down.
removed all of the vanes, and did the ties better to avoid the wobble i had on previous tries.
Finally,some good bubble size and foam worth skimmin at half full...
Little turbulence, but performing excellent.
Install and removal of old skimmer....this part sucked as you can see.
