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.

Hi Aron,
Why wud one take up the hobby if there's any hassle??? :
If you like the hobby, I suppose you sud only feel pleasure and not pressure! ;)

I used to wake up at 5am in the morning, go around picking up friends and drive a long distant into Malaysia just for an expensive game of golf. End of it, I'll be tired and red, but if you ask me if I'm interested to play again tomorrow? My reply will only be what time and which green. Some will only feel its ridiculous. Try explaining to your wife why EPL is so interesting!!!

Thus, this hobby to me is much cheaper and more comfortable. Don't you agree? ;)

Btw, you're in Donguang but know of our water cost here? Are you a Singaporean working in China?
