For those of you with the big tanks!

With my pico, maintenance is a breeze. A cup of freshwater added Dailey and a half gallon water change once a week. Just curios how in the world do you do water changes on a 200+ gallon tank. How!? That's a lot of heavy buckets!
Hopefully I can get one of those someday!

 

40g Brute cans on casters; one with new water, one for old water.

 

+1, thats how I do it.

 

I usually change 10% weekly all 4 of my tanks, which total about 100 gallons. Whole process usually takes about 30 minutes. Might be closer to an hour if I really need to do any cleaning in the tank. Of note my water change storage container is in the basement, 2 tanks on the first floor, one on the second, and one on the 3rd. A lot of stairs are traveled on water change days

 

I do mine in 5 gallon jugs. 8 of them

 

I have ro di set up in basement with two 40 gallon drums, one w ro one w salt. Drilled a hole in the kitchen cabnet and it goes upstairs with a pump. Old water right in the backyard.

 

Yup 40G brute. I use a long hose to the laundry tub to remove water.
40G brute for new saltwater.

 

I have a pump in my sump just for removing the water and a pump from my saltwater container and pump it back into the sump.

 

I replace all the skimmate from my 3 skimmers with clean seawater from a 300g reservoir continuously, via a float switch in the sump. Since the large skimmer is set to skim wet I end of replacing about 100-150g per week. Using this technique I am replacing dirty skimmate with clean seawater, automatically

 

mixing barrel is directly next to my sump in the garage. Drain is between barrel and sump. Pump water into the drain, pump new water back into the tank. about a 10 minute process. I only do about 25 gal at a time though.
