Re: Moving 900 miles away need some insight??? I respectfully disagree. While changing 100% of the water once a month would be allot easier it would be very stressful to the livestock in the tank. Also everything I've read says the MOST you can do is a 50% water change...and that's if there's some serious shananigans going on in your tank. Your best bet is to do between a 10-20% water change twice a month. |
