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

yep i do water changes...sometimes :mrgreen:

50 gallons per week, but I'm not positive how much water I have overall....My guess is that is right around 10%.

8-10% on a 50g weekly - has a Deltec MCE600 skimmer

what is a turf scrubber?

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

:redface: 10% monthly...i see no difference since when i was doing weekly changes. gotta like lazy:redface:

Weekly changes?

Last while ~10% about every 3 weeks.

ok i was just checking im right in the ball park then..... well i guess ... i havent done a water change in ummmmmmm 2 months:redface: just alittle busy at work.. i did a 10 gallon water change today so that is just under 8% and have another 20 gallons brewing as we speek to change out in a few days.. i have a big skimmer and a refug ( roughly 15 gallon) and fun a phosban reactor... i know make time for the tank!!! but in all honesty the is no alge and i have seen more coraline growth in the last month with now water changes then when i was doing them regularly in my old system

I stick to my No more the 5% rule.
In this hobby nothing should be sudden or quickly so small/Slow change is better for me.
