How 'bout them water changes?

I have a 46 bowfront that has never had a water change and is 7 years strong. mostly softies but i have a purple whip and a couple LPS frags that weren't doing well in my pro 55 system that I try to take more care of. The 46gal has no sump or fuge and right now no skimmer either. I dont feed my Dotty or Clownfish either. I had a pistol shrimp that was 4 years old but i think he finally went caput on me. my brittle starfish is also 7, and for the last two years ive had a red linkia thriving as well

 

10% every two weeks. Only dose mag when needed.

 

I do a 20 gal. water change about every other month in a 150 gal. system counting the Sump, Frag tank, Refugium and 2-55 gal. tanks.

and dose in between

 

We do 15% every other week, weekly filter floss in canister filter with ~5% water changed during dumping canister water, with Reef Crystals salt so no dosing. Want to get a sump but no $$ for now.

 

I do 10 gallons every 3 weeks, every so ofthen I dose mag if the mangroves have been suckin it up

 

10% every week. I do notice everything looks better after water changes. I know I would not like to live in a bucket of my own waste so I do water changes.

 

Wow. 7 years and I was worried about a few months! That's amazing.

 

25% about every two months. I would like to do it more often but time seriously flies by.

 

I do 15% once a month and dose Ca and Mg when needed in between.

 

i do a 5 gallon water change on my 40 gallon every 2 weeks
