Simply Koi and More Koi

we dont know the relation or orientation of the pond in the garden so its hard to adjust your diagram. but i think youll find it hard to cram in all the pipework, valves, pumps, UV, air pump and filters in that area. it seems a little slim in the width. a better idea i think would be to have a recta...

Bob that looks like a nice space for a couple of koi to grow on ! at least you wont loose them in the big pond....
or even string across a piece of netting and grow some water cress for the salad bowl

WOW, what a good job there Bob.
i do hope your going to see how many gallons of water it will take to fill it?

how many do you think?

great work for a weekend you lot.

i think looking at that hole Bob it will be about 461 gallons.

no, not motor driven... hand driven but a hoover head that fits nicely across the bottom of the filter bay. you just would turn it on at one end and slide it slowly to the other end and then turn it off. least disturbance to the matter settled on the bottom.

so youll be building a special "Bobbed hoover head" for the filter bay. a nice slotted piece of pipe that spans across the filter bay with a connector for your vacuum glued in the middle. add to this a nice little remote for the on/off switch. a click on the remote and one pass across the ...

Settlement chamber? and i thought you were a "technology person" so Bob are you shying away from technology and going back to the good old fashioned way of filtering water? OR are you making this settlement chamber with a difference? Question:- how will the flushing of such a large volume ...

Bob, if your going to make a new mould for the back/chute then have a look at making it out of "foamex" (the stuff they make signs out of) use the 10mm thick stuff. it cuts easily, sands well and glues together easily. and is a lot more flexible than MDF. also it has a natural waxy surface...

well i must say "hats off to you Bob" for a great job well done. a true koi quester. over engineered, superbly made using way too much fibreglass for the job (you could drop that from a jumbo and it wouldnt break) heres a question for you.... if you were to do it again what would you do di...

good idea with the chute and splash guard, why not include the sides as well then you could just make a flat panel for the front that clips on to encase the whole shower and a little hat for the top LOL. if your using the plastic media tray stuff you might want to add an extra SS bar across the midd...

hey Bob got them showers working yet?

bob as dave says get yourself some proper mould release wax. it contains other chemicals that car wax doesnt and makes a big difference when your using a wooden mould more than once. it also works really well as a car wax :roll: i still think you should stick with the fibreglass and make your own br...

well you have been a busy little bee ...
looking good a very proffesional job Bob.

to stack them why not nock up a length of grp in an "L" shape then cut off 2" lenghts and glass a couple of them on each side of the trough.

graham, how will you see when the sand is bubbling around?
maybe you should have spent an extra tennor on a piece of 4"dia clear tube...

Bob, you seem to have a new string to your bow :D :D i bet your thinking "why didn't i ever try fibreglassing years ago"? my one piece of advice to you if your making your own moulds would be to use lots of silicon free wax and a liberal coat of PVA release agent (special purple sticky liq...
