water changes

[christyf5]

15% weekly sometimes 10% if I'm lazy or need to do a big w/c on my nano

[argileh]

15% weekly on a 29 g tank, skimmerless

[andrewsk]

15% (40 Gal) on my 300 Gallon system weekly.

[Chowder]

I do a 15 gallon water change on about 80 gallon system.

5g/ week on my 45 cube. However, I also only did about 5g per week on my larger tanks but they were running with large becketts and my turf scrubber.

18% (55 gal) on my 300 gal reef with skimmer and moderate fish load.

[michika]

Yeah just 5g. It seems to be the perfect amount as my tank responds quite positively. Anything more and it seems to be unhappy.

what is a turf scrubber?

[SeaHorse_Fanatic]

Turf scrubber = refugium. Usually one filled with Chaeto or some other fast growing, nitrate absorbing macroalgae.

Its a device that has an algae turf dump screen. It grows turf algae instead of the usual filter algaes. With no disrespect, a sump full of algae is not a turf scrubber but an algae filter.

The scrubber screen is exposed to air, as it fills and then dumps. This method is suppose to filter a lot better than just using macro algaes in a sump, but some of us beg to differ. I believe Inland Aquatics uses large scrubbers on most of their large breeding and coral systems.

My unit is in hibernation, as I only have a small tank. Perhaps someday I may use it again. Below is a pic of the scrubber screen and another of a new turf scrubber. I dont have any idea who sells them anymore. Legal issues regarding patents have put them to the side I guess.
