Water Change

[Crazy fishes]

I am very impressed with this and felt that I should share it with you guys and girls. www.reefvideos.com and at the bottom of the selection bar click on Carl's 300g reef. He does water changes every 3 months but no surprise that water quality is excellent with a setup like that !!

Happy viewing

A lot of people are "joining" the no water change "movement" now, and some of their tanks are great. But i dont have the guts or experience to try it.

I would't dream on not doing a water changes every 2 weeks.

I went away to Australia for a month back in April and when I came home the tank water parameters were fine, the Macro Algae I had in the main aquarium had gone ballistic and had to be ruthlessly trimmed back. I'm always tinkering at the moment re-arranging corals etc so I need to waterchange on a weekly basis, once I'm fully stocked I plan to change water on a fortnightly basis. I will still have to top up with RO regularly.

I never do a water change. The only water that gets added to my tank is to top up and thats it. Never had an issue with my tank so if it aint broke. Thats not to say water changes are a bad thing of course but each to their own.

blackperc...what size tank have you got though and what equipment do you run?

When I stopped doing water changes in my fw setup I stopped having problems.

For marine, it depends on the setup -- size of system/total water volume, what sort of animals are you keeping (FO vs reef, SPS or no, etc, etc), what sort of nutrient export methods you use, and what sort of supplementation you use.

If you have a reef with SPS, unless you are routinely adding the dozen or so trace elements that any reasonably diverse mix of corals will require, you need to do water changes. Adding freshly mixed saltwater will be the only way to replenish strontium, molybdenum and all the other trace elements. Dosing calcium and alkalinity buffer in the long run will not be sufficient and the tank will "crash" -- it's just a question of how long.
