Hi this is my first post so be gental with me please!Iam going to construct myself a koi pond which should finish up about 3500 gal with an average depth of 5ft (2ft in ground 3ft raised).Iam thinking of using a concrete collar then 18x9x4 blocks laid flat for the raised part then gently slope inwards to my required depth,then just use underlay and a good quality liner.I will also be fitting 2x 4 inch gravity fed bottom drains which i will incase in concrete!.Iam new to ponds although iam confident in keeping fish, welfare etc and the construction side of things doesnt phase me at all, but its nice to hear from someone who KNOWS what there doing!!!!
My questions are does building this pond in this way seem ok? Also i want to use my 2 bottom drains (4 inch gravity fed) straight to a home made settlement chamber(either block work or plastic bin type)is the theory bigger the better for this type of chamber?from this- straight to another chamber (thinking of putting brushes in this)again home made block work etc and then a submersible pump from this chamber through to a kockney koi mega max filter & 30w uv out of this to a home made trickle tower (hopefully like Alans from this site!)then gravity back to pond via waterfalls with the abilty to divert some or all to a mid water feed as and when needed.
Wow sorry for going on but i suppose i just need reasurrence on wether this seems feasable?
Any suggestions on media which bays etc most appreciated my pond will be low stocked koi only iam working on the theory if i have a settlment chamber then another chamber with some other media in then by the time the water enters my mega black box it should then cope better with the waste etc.
One final question please iam hoping to construct a home made trickle filter from a water butt like (Alans)i understand the the basic set up ie water pumped into bucket in the top with holes in -strainer inside this water out the bottom of butt back to pond but can some one please tell me do i put the air line in the bottom of the butt?then pile on the media?how far up the barrel do you fill with media?and on Alans design hes got holes drilled about a quarter of the way down the butt what size do these need to be and will i not loose water from these?
Thanks for any help recieved, iam most gratefull and this site has given me alot of enjoyment and knowlede already many thanks to you all.
Regards steve
P.s the reason i want my filters set up like this is ive been given all the bottom drains and pipe work and the mega black box so it seems a waste not to try and incorporate it into my system!
P.p.s All settlement chambers/bays and filter box will have the abilty to flush straight to main drainage(i will put valves on my bottom drains to purge etc!!
