danny, if u decide to have only 1 pump, let it be but u need to have a T done at the outlet so that another will be directed to the hole that i told u to build. I hop your water feature water is drawn from the last chamber. reason as epal explain, to direct the excess pressue to your main pond so that firstly, u dont waste the pressure, secondly to save your pump in long run. There should be 2 valve, one for your water fall, the other is towards the pond so that u can adjust when required.

My filter design change over night, now I only need one filter (bought OM2) to pump the water from filter to water fall top. The water will be overflow from pond to filter section (first section)..

add another filter pump, optional, need to on when pond is dirty, to suck out all the dirt..

Hi Danny,

After looking at the latest photo of your pond, I am rather confused with the 'latest' filter design.

(1) You said - "The water will be overflow from pond to filter section (first section)." Are you saying the 1st narrow chamber on the left-hand side?

yes you are right, the first section of the left hand side, you can see it is lower a bit.

(2) Is the original design of bottom drain still there? If so, which chamber based on the photo is it in now?
Yes the bottom drain pipe still be there, but will be change to the direction of the filter pump, the function of the pump, is for additional cleaning of the pond when needed.

(3) What is the new square chamber ? Is it part of your filter?
the new square is the holding place for the filter pump (pump cum filter). Grundfos, model - SM033. There will be a pipe from this section to the external drain, a man hole beside the this section, to the right, that one i added (pay 500 for this additional man hole).

(4) Is the pump (OM2) in the 1st chamber from the right hand side?
OM2 will be at he 3rd section, clean water (on the far right hand side), and will be pump up to the feature wall top.

Any comment please..

Re: [dannysao] My Fish Pond construction [In reply to]	Can't Post

danny, why did u ask them to build a manhole just to place the pumps? already, you have smallish filter and now wasted on placing pumps?

anyway, since its done and now clearly that your set up is quite opp than most hobbyist...confirm that ur contractor is not a specialist but merely some water feature guy...

with whatever done, suggest u keep your bottom drain (assuming it goes to your first filter/ chamber) if its located in your 3rd or last chamber, then forget it and i buy your proposal since that would be the best since nothing much can be done now.

lastly, suggest u get larger fish otherwise all of them will be in your filter instead of pond....

My existing pond place there was a manhole, hence I move the man hole to outside fish pond area, so then only I can build the fish pond, without relocating the man hole, it is impossible for me to have fish pond there..

Hi Danny,

You didn't quite answer my question (2). Which chamber the bottom drain is in, right now? Is it the 1st chamber on the left-hand side?

Can you please describe how the pump - Grundfos, will function in the filter system? ie. which chamber the water is being pumped into Grundfos and where does the water flow to afterwards? Is Grundfos being used as part of the pond filter system or is it used only to clean the chambers?

1. bottom drain - bottom drain pipe will be direct to the filter pump section, not the filter section.
2. filter pump - to suck the water from pond via bottom drain, to give better cleaning for the pond water. as of now the water go into the filter section only via overflow, there is no water from bottom, which will consist of the fish waste, to the filter, hence need this pump to clean up the waster at the bottom of the pond. Basically this filter is like normal aquarium filter pump, where water flow into the pump and pass thru filter then go out. The water from this filter pump will direct to filter section, 3rd chamber of clean water, to be pump up to the feature wall, via OM2 (tsurumi).

I attached the design see, if you can understand.

Re: [dannysao] My Fish Pond construction [In reply to]	Can't Post

Hi Danny,

Ok, it looks like the Grundfos pump/filter is a mechanical filter. It will certainly clear the fish waste at the bottom of the main pond.

The potential outcome is that water will flow in the opposite direction, ie from the filter (1st chamber on the left) to your main pond as well.

Let me explain. Since the water from the Grundfos pump goes to the last chamber (ie right most) for the OM2 to pump up to the feature wall, the water level will go up resulting from the Grundfos pump output. This will push water in the last chamber (right most) towards the left handside chambers.

This will not happen provided the OM2 pumps out more water volume from the last chamber. I seriously doubt the OM2 can pump out more volume without affecting the water flow at the feature wall.

Ya< I think you are right,there is possibility when I on the filter pump, the water might flow from 1st chamber back to pond..good observation, I need to ask my contractor again. Thanks.

Re: [Epal63] My Fish Pond construction [In reply to]	Can't Post

Danny, my suggestion, let the drainage be on norm without any pump as really, gravity will do the trick. Of course, the problem that u will have, is that your pump chamber will overflow or if let be, it will remain stagnant and does nothing unless u switch the pump on to suck the pond water.
From what u have now and minimize hacking work, my suggestion is that u use the pump chamber as your extra filter chamber, call it chamber X. Then make a gap between Chamber X and your chamber 1 (filter) so that the water can flow into chamber 1. the gap should be on the top and not bottomm. With that your so called chamber X will be a settlement chamber where all the waste will be collected at the bottom whilst reasonable clean water can flow into your Chamber 1 and u can make CHamber 1 as your bio chamber if u want to increase your bio filter room. When the need arise to clean your waste, switch on the grundfos (i presume summersible) which will drain out the waste into your manhole....
With that problem solved.

basically no progress for a couple of week now, busy with tiling now. Just finish tiling for my living/dinning/dry kit.
The next thing he wanted to do is to change the bottom pipe to have the water go to the filter Pump section, screw up design, change half way without my knowledge as well, not stuck there. Not yet done. Once this is done then I think is water proofing then tiling.

The wall opening is for water overflow and go into the filter section before it get pump to the feature wall top..

see another pic for filter section..and the bottom pipe hole in the middle of the pond..

Hi Danny,

What is the bottom drain diameter? It looks very small.

From the looks of the pictures, my guess is that main water drawings will be from the "overflow" rather than the bottom drain. I suspect the bottom drain might lose its effectiveness in cleaning up the wastes from the pond floor.

I think it is about 3 in. This bottom pipe is to suck the water to the filter pump (grundfos), additional filter pump to clean the pond whenever needed, not on 24x7.

the pump which is one 24x7 is the feature wall pump..which need to always pump the water from filter up to the feature wall top..

i am thinking of putting tile for fish pond, i afraid it will look very urgly when see the bottom..how is ur pond? do u put tile for bottom?

Re: [Epal63] My Fish Pond construction [In reply to]	Can't Post

Hi
Next door will do the fish pond or feature wall as well, and ask me to top up my wall to the pilar height, because his wall going to be that height..i put some brick there, it is no look nice..wonder if I did not do this, later when next door put up the wall will it impact my feature wall top? my contractor advice is not to top up my wall, just let next door do his wall, then later on my side I just paint black color ..so this is to separate the feature and none feature wall (which is next wdoor wall). But next door said, if I did not do my wall, when they do their, it could mess up my top part of my feature wall...

any ideas are welcome??
