concrete vs liner

[Crazy Taco]

A good uv filter kills desease and other bad things. I swear by them but pond uv filters do not do this they just control water colour basicly

If the pond is below grade, which i surmise it is because the thread starter mentioned digging a hole, then this statement is incorrect. Soil is a very good insulator. Concrete is a conglomerate of rock aggregates that transfer heat faster than most soils.

This is in the indoor pond forum, so I assumed this was inside the house. If the pond is inside, concrete is a better insulator than a liner.

What are you planning to keep in the pond, Kois or tropicals?

From post 1 in this thread:

i have a couple of questions that i was hoping you guy could help me on.
the idea would be building a 30'x12'x5' ingound pond.

-would pond liner be cheaper to construct than a concrete pond?
-why do i see alot of people who used pond liners convert to concrete ponds in the end?
-which material would keep the heat in better?
-how long do liner normally last?
-would a 1st time DIY pond builder have trouble building a concrete based pond?
-do you need UV filters for indoor ponds?

From post 1 in this thread:

Inground in no way means outdoors. I have an inground pond indoors. I have this because of how deep I wanted the pond. I wanted the pond 6 feet deep and it would be very hard to view this pond above ground. Inground just means it is below ground level, not outdoors.

kob got any pics sounds cool ?


also if you have natural light in the pond put aload of plants in and if your bio filtration is good enough then you should be good

I moved away from liner ponds for several reasons over the years. They are more expencive initially...yes but last FAR longer if properly built. If you do the work yourself I don't see a concrete lined pond costing thousands more. That hasn't been my expierance...but they DO cost more up front. You can offset much of this cost by taking your time.

Even the best pond liners fail to live up to thier life expectancy IMO. Especially if you have a large enough pond to require getting into occasionally for maintaince...cleaning...and thinning plants.

Shape and aquascaping is also a lot simpler with a concrete pond. You can create a lot more natural looking ponds that way.

That was exactly my point....

ok, i was reading a few pond books and one of the books mentioned doing concrete ontop of the liner.
what's the point of that?
does it make it any stonger?
when they say using concrete ontop of the liner, how think of concrete are we talking about here?

I have a concrete outdoor pond. 10 yards of concrete. 20x25x2.5 with an attached 36x6x1.5 river. It cost me $2500 total (sand, tile field, wire, rebar, concrete) If you live where it gets cold - don't do concrete. It cracks.
I also have a 12x15x2 indoor pond. I use UV filters on both ponds. Yes, I get algae blooms indoors with the lighting I have.
