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
