Water Change Survey

1. 2 X 55 and one 2 gal.

2. weekly

3. 30-45%

4. I've never had a problem with NO3, it's always right around seven. But... if it hit 20, I would probably do a water change.

5. Would probably do 40%
 
1. 190lt, 220lt, another 220lt coming on line, a 50lt and a 10lt.

2. When I remember or get around to it. Once a month would be nice.

3. 25%-75% depending on how long and why I'm changing it. Usually 25% in a normal change, but when we have rainwater I'll do a bigger change to lower the Kh buildup. I don't change the 50lt at the moment coz there are mousies in there. And the 10lt is empty as I can't think of what would actually live in there at the moment. Maybe a couple of goldfish ;)

4. NO^3 not usually a problem. The green stuff gets hungry.

5. 25%-75% depending on the levels.

1) 3 medium tanks (55, 38, 30)
3 small tanks (20, 20, 10)
2) Weekly water changes (sometimes bi-weekly if I see a need)
3) 50% of water for each tank or more
Tanks are planted, I add nitrate
4) I do EI dosing, so as long as I change 50% of the water I don't test weekly
