Water Change Vs Reverse Osmosis, Water Change vs Reverse Osmosis Options

[ameister]

Let me post a theoretical question...

I understand the need to do regular water changes to remove some nitrates and growth inhibitors. What if we hook up a reverse osmosis system to the aquarium and cycling 20-30% of water through the reverse osmosis system on a weekly or twice a week. Any topping up could also go through the RO system.

If I am not mistaken, RO forces molecules via membrane as it purify the water. It can remove most bacteria, heavy metals and even sodium in some setups. A nitrate molecule is bigger than a sodium molecule, so nitrates will be removed. We can use plants to remove nitrates anyways. As for the growth inhibitor, it should be a large organic molecule and so easily removed by the RO system.

I have recently moved to a flat/apartment and if I were to setup an aquarium big enough for my liking, I dread the water change process that I will be getting myself into.

To all you Goldfish Gurus out there, I your advice, comments and suggestions.

That's a difficult question to answer for everybody

But personally I do a 100% water change every three days

I am not worthy a goldfish keeper...

I am getting even more curious....

Can you please tell me how big is your tank and what is your water supply? If from Singapore, I presume you using tap water. If so, do you:

• 1. Have a second tank, and aerate water for 1 day before?
• 2. Transfer fish to secondary containter, at water, treat water to sequester the chlorine/amines, and return fish to main tank?

Please illuminate...

Thanks

Since you are relatively new in this forum, do spend some time reading the old topics.
Here many of us do massive water changes, usually 80% to 100% weekly,and we do not age water as it will not get rid of the chloramines.

CP, the friend here from Jarkata leh ... if i not wrong, they can age water depending on which part of the water system they draw the water from.

Jarkata or Singapore, Chloramine cannot be removed simply by water aging. I am surprised many people living in countries which use chloramine in their water still practise Water aging method.

I have even read some local old birds advocating Water Aging and preaching it to newbies.
