Weekly WATER CHANGES

[JuanSalgado]

I have a 100 gallon tank & a 30 gallon Refugium so how many gallons of a water change I should be doing weekly. Currently I been doing 10 gallons a week. Is that too much or should I do 10 gallons every 2 weeks, or 5 gallons a week I'm kinda confuse on this. The positive thing is that I don't have any issues with my tank but I will like to keep it that way.

Taking into account the fuge (sump?) wouldn't be full of water and the display tank - if it has an 'average' amount of live rocks - your total actual gallonage is probably about 90-100 Gallons.
10 G a week for changes would be a good amount.

THANK YOU, I'm happy to hear that. I will continue to do 10 gallons weekly.

I have a 110 DT, 38 mantis shrimp tank, and 30 water change tank and about 30 gallons in my 75 sump. I do about 15 gallons a week. Sometimes I even do between 5-7 gallons twice a week. I think that helps me with the no dosing method.

Yes, I'm Not A Fan Of The Whole Dosing Method Either. I Agree, I Just Like It Simple.

Every tank is different man, Reef, fish only, mixed reef and so on. If you have high nitrates you may have to change more.

I have about 90 gals total of water....I change 20 gals every two weeks

My tank is loaded with rock I will put up a picture when I get out of work today but I have a few not so hardy fish in my tank. For example, a clown tang & he's eating a lot and active so I am kinda scary to do a huge water change at one shot and shock the fish and I find him dead the next morning so I'm comfortable with the 10 gallons weekly but I will love to just do 20 gallons every 2 weeks, it will be some much easier for me but hey I rather play it safe.

10 gallons every 2 weeks is fine once your tank is a year or more old.

Some people with really established tanks just do a small water change every 6 months or once a year.

Thanks For The Advice, I have a couple months left, can't wait!

300g systems 50g per week or every two weeks.

I do 20%. It's the same amount of work as 10% for me.

On my 200 TWV I do 20 gallons per week. 4th week I do a 30 gallon. No reason just makes me happy
