biomedia for fish pond?

Question

i would like to know the material properties of biomedia used for treatment of fish pond water.
can i use any inert porous material as biomedia

Answer 1

Any porous inert material will work. Low density ceramic is typically used because it is cheap and easy to form into tubular shapes. Tubes are good because the insides are protected from mechanical damage so the biota in the inside are not disturbed if the media is moved around.

Answer 2

In aqaculture class, we used a sand bed filter for bio-media. the water was pumped up from the bottom of the sand box, and drawn off the top. In the large bio-beds at the local sewer treatment plant they use large river rocks about two feet deep, and contantly trickle the water over the rocks from overhead sprinkler arms. This keeps the organisms alive and functioning.
I guess it depends on what your goals are for the water, and how much energy you are willing to input for the results. a passive bio-filtration system with surface plants- the hyacinth, and duckweed, as well as the porous rock for surface area and microbes, will work- (look up constructed wetland or marshes on google) then again so will a smaller contained pumped unit with sand and occasional chemical balancing.

Answer 3

Hyacinth is a good option to treat water. However, they multiply quickly, thereby reducing the sunlight reaching the water. To maintain the marine life, it might be a good option to use bamboo poles as floating fence to guard unwanted hyacinth growth. Inert porous media such as rocks may help, but they will reduce the volume of water in the pond. Some people prefer to use sand to reduce the muddiness of water during summer time. But this procedure can be used with caution as many fish tend to move to deeper waters during summer daytime.

Answer 4

I don't know if this answers your question or not, but the quality of my current pond of approximately 1200 gallons, and my previous 250 gallon pond is most effected by being balanced with plant life. The cheapest way to a clean pond in warm weather is running your water through a tub or stream of water hyacinths. They multiply quickly, and the roots act like thousands of fingers catching dirt, and absorbing nutrients. Next best thing is Lava Rock, in My Humble opinion. Plenty of sources and sites on the net discussing this. Dave

Answer 5

From the searing i have done any biomedia works for filtering out the unwanted. what i suggest is finding the right inert biomedia for your particular situation. find out what you need in the pond and what needs to be filtered out and then find the appropriate biomedia the fits your needs.

Answer 6

I've always found that if you place lots of plants in the pond and have plenty of wildlife ( fish, bugs e.t.c ) then just leave nature to do the rest of the work.

if your pond has a little blanket weed growing in it then just leave it be, as a little blanket weed ain't no problem to your pond and there are a lot of bugs that like to eat such things.

if your pond is clogged up by blanket weed then its a case of getting your hands wet and pulling it all out.

if your pond is always causing you problems then the easiest thing to do is fill it in and grow a lawn. saves you having to mess with the pond ever again.

Answer 7

Aquatic plant life and lava rock work well. Also... ( if possible ), Next to your pond (southern exposure) place a few blue panes of glass or plexiglass and have the sunlight shinning through them hit the water. If you have your water running/moving at any point such as a fountain, a carbon fliter also helps.

Answer 8

whilst you're finding for "solid hardy fish," don't get stay corals. Corals are plenty harder to maintain alive than fish are. the huge variations are which you need plenty greater tank area for saltwater fish than for equivalent freshwater fish (because of the fact salt water holds much less oxygen, for one situation) and that saltwater fish are much less tolerant of water that's no longer completely clean. additionally, each thing related to a saltwater aquarium expenditures approximately 5 circumstances as plenty.

Answer 9

yes, bio products get caught in the porous material.

Answer 10

Wow! It looks like you stumped everybody on this question. You should get 100 points for that.
