Water change ???

mujtba · 06/28/2007, 09:14 AM

on my 150g tank, with 5 fish, i do 10g weekly water changes.. can i bring it down to 8g weekly or is my bioload too high? what % am I supposed to do on the 150g weekly?

Most people will do between 10%-15% each week or 20-25% every other week.

I do 20% on my 55. It has 8 fish though. For now anyway.

I have a failsafe "water change indicator" in my tank.

Have noticed when my Kenya tree corals/colts get kind of "droopy" and won't fully expand, it is time to do a water change.

As soon as I do, they perk right up.

Happens about every 10 days +/- a day.

I do a 20% change in my 125 gal.

I attribute need due to high tank bioload, or some noxious toxins floating about.

Works for me.

I would stick to 10% weekly water changes, imo.

And as far as your bioload goes, that depends on what kind of fish you have, their size and activity level.

I do 4% h2o change daily in my 400G reef with lots of SPS for 3 months now and it seems to be very stable now. I still cannot get NO3 to 0 (1% now) b/c I overfeed my Tangs and Regal Angel.
