I going to build a koi pond about 10'x6' depth 3.5', a filter about 3'x6', and a feature wall height 6' and width 10' which include all the wiring and piping. may i know how much it cost? is that filter size enought for the koi pond? i need to purchase a pump, which type of pump is suitable for 24/7 usage? thank
i attach some 3d jpeg file for your to veiw. This is my initial design for the feature wall and the fish pond. the piping and filter system need your to help to complete it. any comment please let me know.
i use this thing on my filter system. is that ok? filter1- brush filter2-brush filter3- japanese sponge filter4-bio sponge filter5 and 6- coral,shell and bio ball i attach on picture on my filter system. check attachment.
Welcome to the forum. Based on your drawings, it is good to know that you already have some general idea regarding the filtration system. My coments are:-
1) If possible, try to provide a 4'0" x 6'0" length for the filtration chambers. With that dimension, each internal chambers dimension will have a clearance of about 1'9". This mim. dimension is still possible for the workers to work on it during cement rendering stages etc.
2)Please allow at least a 4" mim. diameter bottom drain piping from the main pond connecting to the 1st. Chamber. In this 1st.chamber or Settlement Chamber, I think it is better to leave it empty rather than placing brushes in it. This chamber will collect the most waste products and normally you will need to clean and syphon out those waste products quite often even though there is a bottom drain discharge connected to the Dry Chamber for back flushing. Hence, it is better to leave it empty for that purpose.
3)I would consider having the following media into the other biological chambers:- a) Chamber 2 - Brush b) Chamber 3 & 4 - Japanese Mats c) Chamber 4 & 5 - Bio-balls, Bio-rings etc.
Thank, thiamwa do you know where to buy the bottom drain drawing attached or can we make it using concrete. i attach the bottom drain drawing for you review.
You may purchase those from Arowana Specialist Centre along Jalan Puchong or Atarikoi in Taman Desa, KL. It is quite expensive and so most hobbyists will just do it DIY when concreting the pond floor together with the bottom drain. Just allow a 12 inches x 12 inches wide and say 3 inches drop sloping toward the bottom drain outlet for more effective waste products collection. Normally, you could purchased those rigid perforated plactic mesh to cover over the bottom drain to prevent small koi from getting into the pipe.
Hi,thimhwa May i know the height of dry chamber must shallow than the depth of the koi pond or the other way around, dry chamber more depth than koi pond. my friend one is the dry chamber deeper than koi pond, he need pump to pump the water to outside. If the dry chamber shallow than we not need to pump the water but the water cannot drain all. is may that correct? which one is better?
The depth of the Dry Chamber will depend on the level of the nearest public drain level where the waste products are going to be discharged. Ideally, if your outside public drain is very much lower than the pond depth level, you could just discharge it out without much problem. The problem only arises when you are face with the outside public drain set at the same level with the top of your pond. In this case you may either have to raise the height of the main pond or have a Pump-Fed filtration system instead of the Gravity-Fed Filtration system.
I think it is very difficult to explain to you in words without having diagrams to show and describe the two different systems. Alternatively, where about are you staying? If you are in PJ or KL, maybe you may want to drop by my house over the coming holidays and I will run you through the whole filtration system. I think that is probably more beneficial for you.
Best Regards, Thiam Hwa

thimhwa, thank a lot for you inviting. could i visit you on this sunday 28 oct. when would be a convenient time to meet? i stay at Rawang. where you stay? i travel to pj or kl need 30 minutes. can email me your address? my email address is lawfucan@yahoo.com.my
The main thing that is how to empty the water on the pond if the dry chamber is shallow than the pond? or the pond water will no empty for koi pond.

thiamhwa, my 10'x6'x3.5' pond is that enought for 10 kois. 18' x 6'x 3.5' is that better for 10 koi? if for 18'x6' do i need to use 2 bottom drain? thank
thiamhwa, thank a lot for your great assistant during the visit on your pond at your home yesterday. i really enhance my knowledge on this koi keeping hobby during the visit. i find that your DIY BIKI shower is very nice. i also try to use your opinion on the insulated the pond by using aluminium sheet to reduce the pond temperature. i will redesign my pond in order to achive low temperature water. i also need to built pagoda on top my fish pond to reduce sunshine to increase the water temperature. i decide to ask my contractor to stop work and redesign all the layout which will include the aluminium sheep,pagoda and a DIY BIKI shower on it and extend the pond size to 18' x 6' x 4.5' if possible. but this all need money. All this need to many discussion and more money to pump in. look forward for me reply after the discussion with my contractor. thank best regards ken

hi thiamhwa, Today manage to talk with the contractor, the pond size increase to 20feet x 6feet x 4 feet depth (3 feet under ground and 1.5 feet above ground. above ground is more safety for my two active sons. ) The water lever is 0.5 feet below the pond and final water depth is 4 feet. the filter will be 3x 15 feet around 30% for the pond size dept 2feet. (1.5 feet above ground+ 0.5 feet bellow ground) The alumminuim sheet that you suggest to consider as insulation to keep water cool , the contractor will consider it and he suggest to add a layer of water prove coating on the inner wall of the pond to perform the same effect and more safe for the water leaking problem. is that ok ? and do this coating can harm the fish? For the bikki shower, we will stand by one pipe from the pump at the end of the pond, if i need to add in the DIY bikki shower. From 10feet x 6 feet to 20 feet x 6 feet another 7.5 k gone. it ok for me to paid one time for the fish pond and use for many years. best regard kenlaw

Please note that the suggestion to use those double sided aluminium foil consisting of a single layer of polythylene bubble layer sandwich in between plus another layer of polystyrene foam boarding on the outside of the pond wall has not been proven that this will reduce water temperature.
Before the commencement of your koi pond project, you may want to consider setting up two mock-up sample in your garden i.e. one water temporary storage unit with this membrane enclosure and another without. Test this out to determine whether there are any different in the water temperature between the 2 mock-up during day and night time. If no different detected, then just throw out this stupid idea .
With regard to the depth of your filtration chambers, is it possible to go for mim. 3'0" depth instead of the 2'0" ? With 3'0" depth, it will accomodate more filter media and hence more good nitrifying bacteria in the biological chambers.
thank for your information , i will change the depth of the filter to 3 feet . but another nightmare appear, they dig the pond and found a sewer just below the pond. now they stop digging and need to change the depth of the pond.
we change the bottom of the pond to 2 step inorder to avoid to change the sewer.

I will suggest you to construct additional 2 main holes for easy maintenance in case of blockage in the future, strictly no L-shape pipe as shown in your plan. Please find my sketch in blue. Good luck.
wsc888, can i man the new man hole smaller compare to standard size, i find that there are no place to put a standard man hole. just 3 feet for the walk way. the width on the area only 10 feet. 7 feet for the pond and 3 feet for the walk way.
Sorry, for the late reply. I have been away on holiday.
Regarding the sewerage piping problem, please check the depth of the last Manhole before it connect to the main sewerage pipeline. If it is much deeper, then you may want to consider re-enlarging the 2 Manholes beside the koi pond bigger to say 2'6" X 2'6" and deeper to allow a deeper sewerage pipeline run between the 2 Manholes. That will allow you to have a deeper pond. Alternatively, you may want to also consider raising the koi pond wall higher than the existing ground level.
Please try not to re-direct the sewerage pipeline if you do not have enough space for the bending flow. You do not want to end up with future sewerage system problem which will clog up your sanitarywares discharge.
thaimhwa, i would like to buy the pump for the pond. please recommand some pump for me. and which pump suitable for 20feet x 6feet x 4feet depht pond.
