How do you do your water change?

wet skimming

i will be getting water in my 75 gal very soon and i think i will try to skim very wet, like 2 gallons a day into a waste collector, and have clean saltwater in my ato. thats about a 80 % totalwater change every 30 days at 2 gallon per day. the down side is having to watch salinity and evaporation closely. i have not tried this before but i have read alot of peeps are doing this, a few for multiple years. for me a couple gallons a day is better the 20 at one time

 

I have a 50 gallon brewers bucket with a power head in for mixing - and my tank is situated on 2nd floor - and next to window - with a drain pipe running down alongside - So I cut into the drain pipe and pump water Via a short hose straight down and out. and then pump water back in from bucket
