So I would probably need like daily 5g changes?Long story short two 10g water changes don't do the same thing in your tank as one 20g water change does. You need to increase the amounts in the 10g water changes.
Not my thing so I just stick to the recommended WC of 50% once a week.
That is very interesting, I may have to look into getting a drop system. Thanks!From: Drip System Water Change Rate Calculator (W.C.S. Ltd.)
Tank Volume 29 Gallons
Water Dripped in per Day 5 Gallons
The drip system will change 15.84 % of the Tank's water in one day and 29.17 % in two days.
Assuming no additional pollutants are added, drip system will replace 70.09 % of the Tank's water in a week.
OK thanks, I'll try to find a calculator to get an exact amount. I never thought about it that way.You'd have to change proportionally more water, since at each water change you're changing a blend of the old water and the water from the last change.
I won't do the math because it's Friday, but someone could.
Hmmm that's an interesting point. I wonder if having more stable nutrients in the tank is better than large swings. Three 5g changes is only 5% less water than one 14.5gUsing zorfox's calculator for dosing accumulation you end up with basically the same ppm over time in the water either way. This is assuming 50% every 7 days vs 20% every other day.
Using the same software if you change ~20% of your water every other day (5 gallons) you will have effectively changed 45% of your water every week... so in the grand scheme of things it makes no difference
The only thing i noticed is looking at the graph that the concentration of what ever you are dosing was much more stable with a 3x 20% water change than a 50%.. i.e. it didn't swing up and down as much over the course of the week... better or worse I have no idea, but it is worth noting
If you'd like to play around with the numbers yourself this is the software they're a forum member as well if you have questions
