Ya you would think wc would be easier to do then constent dosing iv considered no w/c but after a few weeks I get sick of daily dosing would much rather mix up some water once a week to biweekly and call her done lol

because we get good results by not doing so?

i do water changes and get massive cyano out breaks, i dont do water changes i get no alage or cyano and corals happy as clowns
i still do them, just not as often as 'recommended'

The way I see it,after trying both routes (water changes every month and going 6 months without it)I f you like your corals to grow and florish you should have a regulated water changes to simply replenish the ions removed by the inhabitants (not only your Calcium,magnesium,alkalinity)
Every situation is different as in mine I do water changes every 3 months or so simply because entire water volume in my system at the moment is over 400glns and only medium load in a 180glns display and if you know your tank and its inhabitants well some of your corals will let you know when to do a water change as in my system my neon finger leather lets me know same as some of my SPS.My 2c:biggrin:

?? How does that work lol. I had cyano n algae and i beat it off with consistent w/c. Are you not using rodi water? Sounds like your adding nutrients with ur water

Also my pistol shrimp only molts after a w/c and adding iodine seems like a waste since its sucked out of the water quite fast and again just another thing to dose

I dose tlf 2-part, iodine, and vodka.

Dosing for me is taken care of by my dosing pumps, all non-conservative elements are dosed/ measured/ adjusted, my nitrates and phosphates are 0 and 0.03ppm and I have ATO with RODI. Corals grow great, colors are solid. Question... do you think I am doing regular water changes? Do you think I need to do regular water changes? Why/why not?

All u hear is money money and more money lol i run a minimal nano setup so I have to do w/c just to save time and money on dosing n chems. Honestly though my next setup is going to have all the gear to enable me to do less w/c with less dosing hassle

My hobby pays for itself... Wanna buy some corals :) I run 4 isolated systems totaling >400g twv... daily decrease of Ca is 20ppm and dKh is 1.5 degrees. Water changes won't keep up with my dosing requirements. I started out small and grew slowly: like 22 years of growing, so money spending has been spread out and lately has been subsidized. My mom runs a nano and despite having unlimited access to all supplements and test kits, I tell her a 10% weekly water change will take care of all of her needs with, by FAR, the least amount of work. Wish it was the same for me ;).

Lol i can see that haha even with weekly w/c by the next one u would have no calc or alk and i assume other trace elements would be quite low or non existent sounds like a nightmare lol my next tank is going to be max 100g DT will be 60g prob could still get away with just w/c in my case :p
