i love doing water changes on my frag tank but my larger reef is a job in itself. .. I'd love to see you change the larger system's water when is re done.
Hello Vividaquariums, I have a shallow sandbed just like in this reefer 170. Im always having some small diatoms on sandbed after every waterchange. Do you think its because im vacuum my sandbed and maybe disturb some bacteria? I have very fine sand, almost like sugargrains
You mentioned that you prefer an alkalinity of around 8 and the current alkalinity is 10 in a previous video. I'm sure the tank alkalinity will drop to that 8 level at some point, however should we be concerned when doing water changes? Would the difference in alkalinity between new salt mixes (typically high) and tank water not cause the alkalinity to spike in the tank when doing say a 25% water change? thanks
+diggler93 It is always preferable to have the alkalinity of your newly mixed saltwater close to that of your aquarium. When doing a water change of 20%-25% a difference of 1-2 dKH is acceptable. The less difference the better.
+Kayvit Lopez It depends on your Nitrate levels. You do not want Nitrates to rise above 10 ppm. I usually change water before Nitrates rise above 5 ppm.

Thanks for the video. A lot simpler than I thought it was!

keep up the great work
Might want to make sure that the new water is the same temperature as the tank water, to reduce the stress on the critters.
when will you make a new video on this topic? going to buy myself the same tank and equipment as you guys x, LOVE IT!
+Lars Mertens We will shoot again next week. Took a week off for Thanksgiving ;)

Newly mixed Red Sea coral pro water will measure around 11-12 Dkh right?
Yes
Where do you buy those water bottles?
i just keep them when i get the natural sea water from the shop.
Amazon has them - I have 3
do you turn off the return pump when you do a water change?
Yes, otherwise the pump will run dry and you risk destroying it.
How much times/when should you do a water change?

Thanks that really helps because every time I go to my local fish store they always say a bad estimate and yours makes more sense to me.
This video lacked a lot of information...what about RO/DI concerns, replacing vital minerals after the process, salt content and temperature???
lol i seen a couple , everyone shows pipe drain water from tank then top-up , even a three year old knows that
Hi there, where can i buy this containers
Jerry B my LFS has them whenever I buy rodi or saltwater from them
