Koi pond filtration for reef tank?

[Lee adams]

I used to have a reef tank in the UK some years ago so definatley not a noob..
Im in the process of designing a 3 x 500 liter filter for my Tilapia and Koi ponds here in the Philippines and have decided to utilise the same filtration tech for a 110 gallon Reef rank Im in the process of setting up..It all may go pearshaped but I really cannot think why it should.
So my plan is to have a submersible pump in a bare bottom tank..The water line goes up about a meter and 2 meters horizontally into 3 chamber vortex and settlement filter. Then on to a 60 liter gravel and sand filter..From there the water goes into a 4 stage above tank trickle filter with outlet back to tank.. No skimmer for first 6 months and probably never but I may add a UV light and use top half of gravel filter as a refugium. The main tank will be built into a wall with all the filters in back room..A bit like a living wall picture.
We live on an island with an abundance of coral reef so stocking the tank with fish and live rock will cost next to nothing.
I have looked for similar systems being utilised on youtube etc but nothing.. Your thoughts please.

I don't see why this should not work. you will have a great load of both mechanical and biological filtration.

Im using stuff that I have laying around on the property including a 500 liter plastic drum that needs bio media.. Im making large bio balls by rolling up the type of fishing net in pic.. Pretty sure this net will give similar surface area to nylon scrubbies.. Looks like I have about 30 meters of this net which will fill half the drum.
I also cut up 20 meters of flexible electrical conduit into 1 inch pieces ,made a net bag and threw that in also..

The first stage filter from the tank is the vortex and settlement chambers..I made the 3 chambers out of purified drinking water bottles and 3/4 inch pvc pipe.. Tested this already and works like a dream..Any solids entering will 100% not return and can be flushed weekly/monthly etc.
I couldnt work in a trickle or Koi Bakki filter into the system but might add in a separate configuration later...or not.
Obviously, this type of set up is definitely not feasible for most household situations!!

front end.. Luckily we live on an Island with dry coral stone in abundance so the hard scape was all sourced from our garden.

Almost 3 months testing this filter system and it is the most efficient filter I have ever owned..All solid waste goes directly to vortex cannister and is removed from there once month via a 1 inch gate valve..No more disgusting filter socks or ever clogging filter pads..gone forever.
Amazing!

Do you use water from the ocean for water changes?

Do you use water from the ocean for water changes?

Yes..we are just up the road from the local beaches and I fill up 4 x 5 gallon water bottles while we are up there.. Free fish and free water is something I enjoy taking advantage of here.
