Water Changes

[LikeitSoft]

Hey Guys,

I havent had a problem, but I am moving towards a more sps dominate tank. My current tank is roughly total volume of 225 gallons. I am using metal halides. But my question is do you think its okay if I only do 10 gallon water changes weekly? I know people who do 10 percent every 2 weeks. What is the right amount I should be changing out weekly. I want to keep my specimens healthy and steadily growing. I do run a consistent carx reactor.

well if ur tank is doing fine, then just keep doing the same thing, it's more about bio load , so as long as you are not adding more fish or change skimmer, u'll be fine. In fact, i know some people with nice sps do water change only once a week.

however, if it's my tank with that much of water, i would do at least 25 gallon a week which is 10%

I do 5G weekly on my 28G

I started doing 5 gal a week on my 46 but I thin it depends alot on how good ur filtration is from what iv heard, been told, and read... But iv only been reeding since July lol so don't quote me haha

What do you have in your tank right now? If it's totally packed with fish and corals you will probably need to do a larger water change.

In my 225 i do a 24g WC sometime i do a 50g WC a month

i have a 120 and i do about 20 gallon thats just me

I have 220 total gallons and used to do 2x40gal changes per month. Now fully automated and I do 5gal/day 5 days per week year round. Corals are very happy.

Thanks one of my web designers at my office did that for me.

That's a very subjective question. How much water changes you do are dependent on how well your tank is set up and how stable it is. I have a 150gal and i do 10 gallons first of every month. My tank is 95% sps. You can check out my corals here ....

Currently Right now I only have a yellow tang in there and I dont feed the tank at all. I have intentions of adding a pair of sanjays black photon clowns in the future. But generally I do not feed my tank. So if my total volume is 225 everyone suggests 10%? would that be monthly, weekly, bi-weekly?

My current regment is 10 gallons every week.

I have a 75 and do 10g weekly, but I have alot of fish.

 

[casademurphy]

I have a 125 and change 15g every 3 weeks. My tank is doing great!

How many fish in a 75 is a lot of fish?

Its going to come down to how much bioload you have, what your parameters are doing, and what you are trying to accomplish with your water change.

If you are just wanting to keep up with Ca & CaCO3 Mg etc then I would suggest topping off with kalkwasser and running a Ca reactor but you will need to be adjusting both as you add more SPS.

If its because you want to export wastes out then I would say depending on what your levels are then 10 gallons is going to be ok or too little. Ok in that changing 5%ish of your water once a week is fine if things are stable and normal (0 or close to zero) but too little if things are higher than that or you have algae problems.

Maintaining calcium will be your biggest issue. Water changes help with that but you'll likely need to supplement too. Do you have a calc reactor or have other plans to dose for calcium?

90 gallon here and rarely do a water change, maybe 2-3 time a year and only 10 gallons each...

I have 4 tangs, 2 B&W ORA Clowns, a Diamond goby, a flamehawk, and a yellow coris wrasse, not sure if the wrasse is alive. I bought it 2 days ago and it dove in the sand behind some rocks and I haven't seen it since.

And I am thinking of getting 2 fish from Ergin.

Oh and the fish are fat healthy and happy.
