310 gallon water changes?

  • We are currently upgrading MFK. thanks! -neo
I think it depends on what you're planning to keep in it.
 
what you stock it with as well as your filtration will play a large role in determining how often you do water changes and how much water you remove when doing said changes.

on my 240gl that i just re-stocked (somewhat heavily) i have the two overflows draining into separate overflows. both are 40gl bringing the total gallons to 320. i had to laugh when the guy at the LFS i always go to said it was overkill.

he was right. my param's are great and i only have to do a 25-30% water change every 4-5 weeks.
 
I say hook both tanks up to a huge sump (maybe 100g) and take water out of there and put tha water in a storm drain.

This man ^ is exactly WRIGHT! LOL

Seriously, if you have Hella filtration on there, you will not need to change the water weekly.

I am an overfiltration FREAK! As an example, I have a 180 gallon which my filtration turns the water over @ 1,920 GPH. That's almost 11 times an hour...

I have it heavily stocked and MAYBE do a water change every 2 months. Most times it's 3-4 months. My water is crystal clear and my fish are some of the healthiest you'll ever see.

Invest in high filtration and you will be ok.
 
If your only concern is carrying the water, why don't you just siphon it into a drain in your house with a long hose?

... a little wasteful maybe, but a lot less hassle.

both of ideas are incorrect

the idea behind water changes is to remove compound that filteration can no longer remove or break down.

filteration will not remove the lot of dissolved organic compounds, everytime you dont do a water change (whether it be food, conditioners, salt ) whatever you put in the water will never come out and it will accumulate over time, to dangerous levels.

now back to the mans water changes

whether his filteration is average or superior will not affect how often he has to do water changes, only his stock load will determine that.

filteration will only keep in check the build up of ammonia, nitrite and free floating debis and detritus, nothing else.
 
Adequate filtration is key, as is proper water changes. If you overstock, you need to do a higher percentage of water with each change. Otherwise get a drip system. There are no shortcuts to keeping a healthy tank.

BINGO

if you arent willing to do the work for a large tank, were you really ready for one in the first place?
 
i dont recomend ever changing more then 25% of the water at a time
i do 20% changes 3 to 4 times a week
more if there are anything that even might be a problem
changing water more then 25% at a time can be dangerous though
