Opinions please on large water changes

  • We are currently upgrading MFK. thanks! -neo
Fair play to anyone that does more than 1 a week, I had a drip setup but oddly found myself missing waterchange Sunday, it's part of my routine lol...
 
I've always done 60%+ water changes with nothing but great success. But just a few weeks ago I did a 75% water change while the town must have been doing something to the water lines. Had a HUGE ph spike and for the next 24 hours was extremely concerned I was going to lose my entire tank. While it is the only time I've experienced that in all the years I've kept fish, it will certainly be in the back of my mind when I do large water changes now.
 
I've been turned on to fin level changes by "pops" on another forum. I have a 175 bow front with one 7 month old red Oscar, seven red hook silver dollars and one royal pleco.

For the last seven months I've been doing a fin level water change every second day with three feeding daily. My nitrates never exceed 20ppm and the fish have grown at a good rate.

As of Dec. I started feeding twice daily with a fin level water change every third day now, nitrates still never exceed 20ppm. After reading this thread the large changes are a concern due to the city water and what changes may occur.
 
Normal city maintenance of city water mains requires flushing the system yearly and after repairs, floods. To maintain a minimum choline content.
This is noticeable at your tap with milky white air bubbles and some air sputtering out.
Generally 2 ppm chlorine are maintained at the far ends of the mains. With opening of the fire hydrants.

I do fin level changes on my 180 but the fish that are in it are about six to eight inces tall.
 
water change Saturday. 180 done, 95 draining and vacuuming done. 145 next.

I had no visible signs when I had variances in my water source.
 
in winter when the water is colder it holds more gas, this reflected in allot more micro bubbles. flushing the lines have nothing to do with that. water just allot colder.
 
After a repaired water main. The air, water hammer will make your water heater sound like it's about to blow.
We get muddy, air bubble filled tap water when the water treatment plant gets flooded every other summer. Des Moines, Iowa.
 
I don't think so. I drip 280 gallons a week in a 540 gallon tank, and nitrates always test yellow. That's about half the total volume of the tank + sump per week. I'm moderately stocked I think in that tank.



Nah, I was hoping you'd answer with something easier than a drip. Drip is easy, but I'd still like something easier.
only thing i can think of that's easier than drip is not keeping fish at all lol
