water change in over filter tank

[duanes]

An FX6 or even 10 of them, or any other normal filtration unit, does not negate the need for water changes. You can help a little by adding plants, or a planted sump that use up some nitrates. But the only real way to get rid of nitrates are removing and diluting them with water changes.

cool thank you so much for your response... i think i need to do more research about nitrates.. since im in a quiet save spot for the amonia and nitrite lol..

but if you were in my shoes, given my situation, how often you would do the WC, and how much water?.. thank you so much =)

you mean only using pure drinking water is not a good option when doing WC?..

i did a quick google search about the Aqua mineral water..
"Danone Aqua Mountain Spring Water: Nitrites/Nitrates 0, pH 7.0, Carbonate Hardness 0, General Hardness 0"..

any comments?.. thank you so much..

That has no minerals to buffer, so it will quickly drop and kill your fish,

at least 25% a week, ask around locally to see what people do with fish there. I'm sure you have options

Other particulars that you have to look at is: how big is the fish right now (of course a 16 inch fish will produce more waste than an 8 incher) and how many feedings in a day will you do? More feedings=more waste= more wc

my expectation by having 3 FX6 is that i wont need to do much water change.. perhaps once in a month or perhaps once in two weeks... but sometimes expectation is not the same as reality

Hello; Since joining this fish forum a few years ago I have sensed a belief among some that more mechanical filtration will some how "take care" of water quality issues. Power filtration for aquariums is a good thing. I use them. They are limited as any tool can be in what they can take care of. That you are aware of the need for water changes already while being new to the hobby is a positive. Having the three power filters will not hurt a tank other than a bigger electric bill. The water currents set up by so much mechanical power might bother some fish, but likely not the fish you plan to have. Others who have kept the fish may give good advice about this.

let say U.S.A where the tap water is save to drink,

Hello; Water here in the USA can be and is bad in some places. Flint Michigan has been having an ongoing water quality crisis for some time now. Too much lead in the tap water. You are not alone.

The filters deal with Ammonia and nitrite

Hello Hendre; I hope to not be too picky in my response because you are correct in some respects. There are bb colonies in the filters and these bb do the job of using fish wastes (Ammonia)(and ammonia converted to nitrite) as their "food" during their life processes and in effect removing these toxins from the water. The picky part of my response being that these bb colonies can and do exist on many, if not most, other surfaces of an aquarium and not just in in the filter. No offense nor disrespect intended.
I will add a link about aquarium cycling later for the benefit of the OP (Original Poster).

The final product is nitrates, not so deadly but need to be kept down for the health of fish. This is only really removed by waterchanges, thats the only way.

Hello; This is correct. The bb eventually convert the ammonia and later the nitrites into the nitrates. These nitrates accumulate in the closed system of and aquarium and need to be diluted with regular water changes. How much water needs to be changed being the question. My take is an big fish such as the OP wants will produce a lot of ammonia and will need a good amount and frequency of water change.

Aquarium cycling link


http://www.americanaquariumproducts.com/nitrogen_cycle.html


Hello; The above link in one I keep going back to as a reference. As you are new to the hobby, I will make the unwarranted assumption that you know little about aquarium cycling. The fish you intend to buy seems likely to be an expensive one. If the new tank you set up is not cycled properly that may wind up being a dead expensive fish. The link has sections about a few ways to "cycle" a tank. May I suggest you use one to get the tank ready.

Bear in mind the balance of a cycled tank is dynamic and ongoing. The bb need their food (essentially ammonia) available all the time. A tank does not get cycled one day and stay that way unless the bb have an ongoing source of ammonia.

thank you so much S skjl47 ..
so if add some small fishes to the tank, and feed them regularly, before adding my arowana (which will eventually eat em later on).. how long the tank would be fully cycled?..

thank you so much for sharing infos to me

Hendre i just did some quick research about dechlorinate thing.. so i think this will be a doable solution for me..

i will see if the LFS here have "prime dechlorinator" , so i can just put my tap water and add the prime solution to the tank directly.. but first of all i need to check my tap water parameter first

Good then. Prime is a very dependable brand and very popular.

I highly suggest you do a lot more research before taking on a fish like an Asian arowana. I would kill for one of those

yeah thats why im asking here and there hehehe.. my tank will be ready in bout 2 weeks, i will get the fish when i think i am ready.. right now im just preparing the equipments and the knowledge needed for the tank and the fish hehe..
