Water changes with planted tanks

[martinshaver]

What does everyone do for water changes. I hear some do 50% once a week, some say just siphon off the bottom and top up.

[Tarobot]

depends on how much of what you have in what size tank

Here is some water change information of some BCA members.

How frequent do you do water changes?
How much water do you change?

Say a planted tank that used to look like this: This was my old tank but I am redoing it.

Hi, your tank look very nice.

i do a 40-50% change once a week every sunday. My tank is a 77 gallon planted.

what ferts are you planning on using? if you are going to be EI dosing then you'll have to do a 50% to keep the fert levels correct.

Depends on a lot of factors:

Lighting level
CO2/Excel?
Stocking level
Substrate type, etc

If you are doing EI then 50% a week is a standard, but there really isn't such as thing as too many water changes if you are dosing.

Lighting is a tek fixture. T5 HO 4x54w. Co2 is compressed with an inline atomizer. Fertz are dry from aquariumfertilizer.com

Substrate is aquariumplants.com's substrate and stocking about 50 tetras

I would advise starting at the EI recommended rate of 50% per week as a minimum then.

I myself do 50% weekly water changes but aiming to do 2-3 times a week when I have more time after I graduate... as I plan to keep discus in the future... and keep the water as pristine as possible... without having the fertilizer levels going a bit too higher between each reset...
