Water Changing Idea - Similar to a bathtub..

  • We are currently upgrading MFK. thanks! -neo
I do this for draining/filling my 300g SW tank and 50g QT.

I love it! I like the fresh water top off idea. You already have the plumbing for the saltwater so it's an easy mod! Kewl :headbang2
 
Interesting but seems overly complicated. Drip systems can change any number of gallons dependent on the drip valve used. I change about 100 gal per day between all my tanks that are on the drip..

Are your tanks salt water? The above is a saltwater plan.
 
If anyone can simplify a drain/fill system to work like a toilet, please let me know. (Where you only have to push a lever and it drains and refills by itself.)











...oh wait, I already did.

Nice job RegalAngel! My design is similar, but controlled by a timer. You can automate yours with solenoid valves and a timer/controller.

Why? Seriously, I'm not trying to be a pain here (insert other adjectives, been called all of em) . Why would you automate such a simple concept? The simplest way is to overflow to a drain. The least amount of stress on the fish is to eliminate the water change forever. Nothing beats a 24/7 trickle system that over flows to a drain. Add new/clean water to the tank it over flows to the sump and then over flows to a drain or back yard. Set up a 1 gallon and hour flow or two or three gallons an hour, what ever gets the nitrates to zero, then your done. No timers to break, no valves to seize up, no power outage issues, nothing but simple. Fish hate water changes, why dump 20, 40, 60 gallons into a tank at one time once a week when you can stretch that over a 24/7 system that only adds a gallon an hour. That's gota be less stress on the fish? Also water keeps running even when power goes out, so the water changer is working even if the pumps are down. Might not be enough for the fish to survive a week but it will get them through the night! Anyway just my .02 on automation and complicated plumbing.
 
Back when I was in school, I came up with my concept. I was the president of the Mechanical Engineering Honor Society, and had access to some university funds. The auto water changer was my ticket to a giant fish tank in the engineering building's atrium. I got approval and funding from the university, but my group wasn't ready to commit to its ongoing care (that's when I looked into the maintenance free concept).

edit:
The university wouldn't pay for a fish tank, but they would pay for an intellectual project. That's why a drip system wouldn't fly. It had to be Rube Goldberg style with tanks draining and filling by themselves.
