Water changes for 50-75 gallon tanks

birch · 09/18/2008, 04:21 PM

I was thinking of upgrading from a 12 gallon nano to a 50-75 gallon tank and I want to know everyone's water change schedule and amount for this size of tank. Thanks.

I have a 55 gal and do byweekly changes of ten gallons may cut it back to 5 every week to keep my algea down. The algea seems to clear up after every water change

bi weekly

depends on how many fish you have. if there is only 3 fish in there just once a month is fine as they are not putting a heavy load on the water. this is assuming you have a skimmer. my 180g with 14 fish i do a 40g WC every 3-4 weeks

I would do 5 gal a week for a 50 gal

I have a 46 gallon tank and change 2 gallons twice a week and then 6 to 8 gallons on the weekend. Kind of overkill but it works out for me.

Really depends on how it's set up, but generally a 10% water change every 2 weeks would suffice. I've followed that routine for years with good success.

I have a 58 gallon and change 6 gallons (roughly 10%) per week). I have 5 gallon salt buckets market on the OUSIDE in one gallon increments with permanent marker. Handling a full 5 gallons generally means sloshing it over the side, but using 2 buckets filled to the 3 gallon mark is easy. If you similarly mark your "waste water" bucket, siphoning out exactly what you need to is easy. If you don't have empty salt buckets, the 5 gallon paint buckets from Loew's are essentially the same thing.
