Boiling WC water/Can I do this??

I have 55gals of fresh and saltwater about 20 ft from my sump and a valve is all I have to twist to do a water change ! I just did my first Water change in over 20 yrs .. I have had tanks run yrs with a good filtration and carbon and no water changes I do add supplements unless I run a ca reactor no such thing at new water its just filtered and or diluted and treated water . Its all been here since day one .. I just did my first one last weekend , Long story short tank was over ran with Bryopsis Pennita and I was not able to do anything and I have it loaded up with algaecide trying to kill it off I did just change 55 gallons trying to wake this 180 up from a 1.5 yr sleep as I was unable to do anything with it. I know where the algae came in from and I had the healthiest and as nice a looking corals as anyone could have ..there are some photos of it around this site somewhere , A good skimmer and high quality carbon is the key for me.

 

I like the "twist and fill" method! I do have a valve and about 50 feet of tubing...Hmmmm. Easier than dragging 5 gal buckets across the room! Fortunately, my tank is in the finished basement, with a floor drain about 5 feet away, so emptying the waste water is easy. I'm looking for pics right now on that 180!

 

The thread for our tank was posted by me so that might help you find it a bit easier

 

Thanks- I wondered why I was having so much trouble!
