Reduce water changes! REDUCE WATER CONSUMPTION!<span class="smallfont"> <b>(2 Viewing

With all the MFKs having between 500gals to 5000gals ++++..

I was just wondering how do you avoid those weekly 100gals++++ water change?!

There's like droughts in some parts of the world..
I have like a 500 gal outdoor pond but a very little 2 5gal gravity filter and a 9w UV Lamp.. My bad!!!
The water's pretty green!!!
Damn DIY!!!

The weekly 100gal water change don't seem to help with the green water. And the amount of the water change seems like hell to people in somalia...

Maybe I'd change them oscars & pacus and just put on 1000 angelfish and neon tetras!!! hehe!

HELP!!!

UV sterilizer for green water.

Got The UV already

Got The UV already

Perhaps 9 Watts is not enough. I think you need to go bigger. We run a 40 Watt UV sterilizer on our 300 gallon tank. The 40 Watt UV cleared up the green water immediately.

tnx! how often then do you do water changes?

 

[pirarucu319]

yup..
UV Sterilizer/ UV Filteration used to disable algae.
UV light having radiation that kill cell..
that totally reduce water consumption..
UV Filter used depend on how many volume of water..

If you are simply trying to get rid of green water you would aim to run a UV clarifier not a UV sterilizer. The clarifier will take rather less power than a sterilizer and a quick Google for pond equipment shows devices of less than 13 watts being more than adequate. Though it is important to remember that you should change the bulb frequently and keep the quartz glass sleeve clean.

Many manufacturers of pond pumps will provide a clear water guarantee, so confident are they that the few watts they provide will be sufficient to remove algae from the water column. This is with the proviso that match appropriate equipment to your size of pond; whether this would apply to indoor tropical ponds is hard to say. Of course this rather assumes such products are available in the Phillippines.

If you are not doing large water changes then there are other technologies you can borrow from the regular outdoor pond hobby. For instance, you can operate a solids handling pump and run it through a cyclonic filter or use filters with basic backwashing facilities so that you can remove solids before they contribute to you bio-load and thus provide nutrients for algae.

Edited to add:
Incidentally, water isn&#8217;t a natural resource that you can use up. In some parts of the world there are shortages, in others it just drops out of the sky in great lumps. If you&#8217;re somewhere with an excess then you're not helping those guys living where there isn&#8217;t much by not using your own.
Water changes are always going to provide the most satisfactory solution so long as you can afford the water and so long as the water isn&#8217;t polluted. From minimal research you get about 80inches of rain a year in your part of the world, so go crazy and crank up your water changes!

How about some real spec.s on the pond?

Physcial size?

Water chemistry?

Bio-load (fish)?

Feeding schedule and type/amount of food?

Type of filtration?

Water turnover rate?

Sunny / Shady?

Pix would be nice...

Small ponds... cover pond completely for 3-4 days so no light can get in (no peeking), you need to break the algae life cycle.

Need to know the other stuff to answer more than hypothetically.

If you dump you W/C in you Eco-garden by the time it filters thru the earth to Simolia it will be clean again so the should love you for your W/C's as much as your fish will.

This is one of those thought provoking questions (at least for me). We are going through a very dry period in my area. The rivers are barely flowing. I feel a bit guilty using 120+ gallons of fresh water every week for water changes.

Is there something I can do to my "used water" to remove the nitrates and other impurities and be able to use it in a week for my next water change? It has to be something relatively inexpensive and not require a lot of work.
