We live in a very hard water area and have problems with sediment in our water, we have been now been told to put one cup of Chloras (which contains sodium hypochlorite) in our water treatment filter a day. Is this water safe to drink?

Dual media filter is a type of filter used to purify drinking water. It is used by water treatment companies. I want to know the advantages and disadvantages of using dual media filter.

Dual media refers to the number of filter materials in use. For example, the first stage of the filter might be one to catch the coarse particles such as a pleated fine mesh paper material. The second stage of the filter could be a finer mesh media or maybe a netted bag of carbon particles to remove smell or taste.

The advantage of course is efficiency of the filter and effectiveness. Different conditions dictate what media choice you make. The best method I have encountered is of course, a graduated mesh media, starting with a larger opening mesh, then stepping down to a smaller mesh and so on. The final stage of filtration would likely be one that removes smell or taste from the water. The bottom line in advantages is that the fewer number of passes through the filter, the better as long as you achieve a good end product.

I need a reliable source for source citation. I cannot find a source that says specifically how long it takes water, once used, to be filtered by nature back into a drinkable form. I know how long it takes to go through water treatment facilities, but not through the natural process.

I've always heard that once water travels through 12 feet of soil and subsoil it is considered "in speaking terms" to be filtered.
This in no way doesn't absolutely mean it couldn't contain a micro organism if there is a source of continual pollution upon entry into the soil.

specifically in replacing new water.

all i know is to pour some anti chlorine and methylene blue after changing a new fresh water.

is it ok to pour those chemicals while the fish is still there? some said you have to pull out the fish first before using those chemicals and put them back afterwards inside the aquarium after using those chemicals. for more or less 5-10 mins.how true is that?

my equipments are irrator and overhead circulating water filter w/ submersible pump.

please advice how do take care of this fresh water pets.

thanks.

No, you should leave the fish in the tank when you do your water changes; removing him is stressful and unnecessary.

You should not use methlyne blue unless your fish has fungus - meth blue is an anti-funguside, so unless you're treating for something, don't waste money on that :)

As for when to put in the water conditioner (anti-chlorine) depends on how you do your water changes. I'm still using the antique bucket mode. That is, I use my clean 5 gallon fish bucket (never had cleaning products in) and with a syphon tube I vacuum out about 30% of the water, which I dump (or use to water my plants). Then I fill the bucket back up, make sur ethe water is the same temp as the tank, add the amount of water conditoner for 5 gallons, put the water in the tank, and repeat until the tank is filled back up.
However, they have "python" tubes, which attach to the sink and go right into your tank, so you just turn the water on (make sure it's the same temp) and it flows right into your tank. In this case, you need to add the amount of dechlorinator for however much you're replacing, before you start running the water into the tank.

You should do these 30% water changes about once a week. And it is almost never necessary to remove more than 50% of the water or remove the fish from the tank (unless there's an emergency, like if you dropped a whole jar of salt into the tank or something).
