Hi all,

I would like to connect some type of pre-filter (charcoal/micron??) for chlorine (at least) to the output of my tap prior to re-filling the tank.

I have seen many on the Web, but the less expensive ones ($100-200) only seem to deliver 5-10 gph, which seems like it would take hours to refill 90-100 gallons weekly

I also live in an apt and want/need to hook/unhook easily, so no perm changes/plumbing. Plus, I would like to put away when not in use, and not clutter the countertop.

Maybe some sort of under cabinet setup where I just quick connect the flex tubing when needed, so it is coiled neatly????

Extraction is easy with a spare pump and some 3/4 tubing, but the refill has me puzzled a bit. Plus, no permanence.. (but would love to have the auto drain type stuff I read about!).

Plus, one of my tanks is at least 20 feet away from the tap, so distance is also a bit of an issue.

Many thanks,

The ability of a carbon filter to remove chlorine and chloramine is dependent on how long the water stays in contact with the filter. So, high flow rates would require a BIG filter. Why not just use Prime to neutralize the chlorine and chloramine?

I took your advice and it worked fine....

I was replacing plumbing/hoses/valves/etc and installing a new bigger trickle filter and had removed about 75% of the water on my 180.

I have/had a phobia about putting any chemicals in my tank, epecially these days where products seem to claim omnipotent powers when used, when all I want is to remove the chlorine/chloramines.......

I used to use bottled water for large 50% water changes every 3-4 weeks, but since I want to switch to EI, I need to do this weekly, and was concerned about the use of tap water for such a large regular change.......Plus the expense of bottled water, not to mention the carbon footprint to have it delivered was bothering me a lot. Now that I use tap water, my conscience is clear(er) and my wallet is a little fatter....

Not sure if they were excited by the work or the large WC, but one of my Bosemani males and one of the SAE both jumped into my lap while I was checking for leaks. No harm, but glad I was there............

Thanks again for a great suggestion.........

Now that I have the setup to easily drain/replace for large WC I will do 50% weekly............

Seachem Prime so far in my experience is a terriffic product. I add it directly to the tank while filling it with a hose and have had no ill effects. It also goes a lot farther than a lot of the other dechlorinators out there.

I understand being leery with all the poor products out there but I think you can rest assured that Prime won't hurt anything and will work as stated.

Couldn't we make a DIY prefilter useing PVC pipe and fittings with screw on caps for cleaning etc with a screen at the bottom and then some filter floss, filled with carbon? The water flow time could be regulated by the tap. It could be 2" in diameter and 24" long or what ever size you would like it.

Would there be any benefit? Cost effective? etc? How long would the carbon last if only useing it for filling the tank and top offs? Would there be any problem with it setting unused for a week or two at a time? Should it be drained? Any other concerns would also be helpful.
Thanks

Crazymid,

Yes I have a large 2 liter bottle of Prime on order.

I just needed some reassurance that others used tap water with some type of conditioner with no adverse affects on plants or fish

Joe,

I think Vaughn nailed it when he spoke about the duration of contact time with the charcoal or media.

If you use a large diameter flow, the contact time will be lessened and the effect on the water would be less. If you restricted the flow to the filter to prolong the contact time, it still would not be that much (I think). Plus, unless you wanted a VERY SLOW flow rate, a large media would be required. Imagining it makes my head hurt

I think you can do it, but not sure it is worth the effort.

I will however use some type of spraybar or DIY to try and mist or spray the output from the tap into the tank. I read somewhere that this will help to dechlorinate. Not sure if true, but it can't hurt.

Thanks to all for the input.

Can you confirm that I am understanding this correctly?

You recommend doing the following:
Drain aquarium tank (50% or whatever)
Add Seachem Prime directly to the aquarium tank.
Take your hose of city water and put it directly into the aquarium tank.

What about other supplements such as Banking Soda for PH adjusment; macro or micro nutrients for the plants?

I have a 125 gal tank. Are you doing this for a 125 gal tank or similar size?
How long have you been doing this without adverse results to fish or plant?

tks

Hi,

I have a 180 gallon tank. I use a 500 gph pump to drain to the desired level (50%) weekly.

I have been doing this now for 4 -5 weeks and NO ILL effects on fish or plants. Quite the contrary actually.

Add PRIME to remaining tank water.

Refill from tap.

Any GH booster should be added at this time.

Please navigate to the Estimative Index on the Forums tab for dosing strategies and amounts.

Hope this helps.

I know other folks do this for larger tanks than mine, so I feel it is pretty safe.

Thanks for the reply.
Well, I'll take the plunge next water change. Next Sunday.
I don't have the Seachem Prime but, AquaSafe by Tetra Aqua ; the container says that it's "Made In Germany" and that should be worth something, technologically speaking.

For those of you that just put the hose in the tank and fill it up - how do you match the temperature of the water? Do you have the hose connected to the hot and cold source and get it lukewarm before filling? Do you just add cold water to the tank?

Thanks,
Aaron
