SPS Veterans, how often do you do water changes?

[DaddyJax]

10%-15% a week.

 

[gcarroll]

For me 5 gallons every 2-3 days to replace skimmate from wet skimming.

 

[Sk8r]

10 % per week, because that 's how many buckets I have.

 

[damienkee]

10% every other weeks

 

[clkwrk]

20% every 2-3 weeks

 

[EnderG60]

thats like 7.5% a week, so 30% a month. [/B]

actually thats more like around 10-15% a month

 

[Frankysreef]

25 gal every 2 weeks.

 

[poknsnok]

25 gal every week

 

[jjmcat]

I do between 15-20% every other week, on average.

ditto

A decent water change article by Mike Paletta that states that 10% per month is all that is needed. Not sure if I agree but worth the read anyways.

 

[Rungeg]

I do water changers everytime I have a big spill (Once a month) generaly 7 gallons.

Roughly 10%

Interesting Travis. It does make you realize that all WC's are not equal. People I know, like clkwrk & Northbay 101 - both with BB tanks - syphon out detritus (so do I). So maybe a 15% WC for them is equivalent to maybe even +30% of someone just replacing water. There is exponentially more "bad stuff" in detritus, than the random water column.

Most folks with Southdown or superfine substrate don't syphon off the bad stuff, its almost impossible.

 

[Travis]

That is a good point Fliger. It probably has a lot to do with what you are removing with water changes. I think that article did say it was a berlin system and that all the detritus was siphoned with each water change.

I also run a BB tank and when I do water changes I first add a filter sock to the overflows and then blast all the rocks. Then I let the detritus circulate/settle for an hour and blast the rocks again. I do this a few times for a few hours until there is almost no detritus left blowing around and then siphon any detritus piles in the tank and in the sump.

Have you seen the pic's of Greg's tank? There might be somthing to what he is doing.
Myself 15 gal evey 2 weeks on a 120 gal system.

 

[JB NY]

just under 15% every week. All detritus is shiponed from the sump and refugium each week, and the skimmer gets cleaned as well.

 

[Lunchbucket]

i do about 15gal every other week. that should be somewhere around 20% + every week. i siphon all the detritus from the sump ever water change

prolly around 50%/month

Exactly the same here. But I clean the skimmer a couple times a week, I do not have a very strong skimmer. I am not a veteran though .

[scarab65]

No veteran here too but I do 5% every week coz that's the amount I can siphon from the tank and sump without turning off the return pumps.
