Will untreated water kill off BB during waterchanges?

  • We are currently upgrading MFK. thanks! -neo
I don't doubt it haha, I'm really sick of spilling water.
 
I use a garden hose for all 6 tanks. No problem at all. Only consideration is temperature if. I need to do a large change in the middle of the winter. March - Nov is great though.

You can use the garden hose to start its own siphon too. Hose in thank, turn the water on, turn water off and unhook from hose bib. Tank will drain with no water in your mouth.
 
I turn my filters off since I drain the tank below the intake levels. Then I add enough dechlor(safe) to treat the entire volume, then refill with the python. Never had a problem doing it this way.
 
Thought about this as well. The only reason I am trying to stay away from turning my filters off is because I run an eheim 2217 and in the past turning it off and on during waterchanges is a pain lol.

Why is it a pain? You unplug it, then plug it back in. What problems have you had?
 
It depends on your water. Here in michigan we can use straight tap water with no problems.
Wise words. We can all sit here and offer advise based on our own (and possibly very different) water supplies, but you'd be best to get a report from your local authority to find out just what goes into it. Talk to other local fishkeepers who use the same water supply and find out what they do.

or a garden hose..

Garden hose has always worked for me too, just take off the regular spray-type nozzle and replace it with a tap/cock that opens and closes easily and doesn't jet the water out at high pressure. Spend a few bucks on a siphon hose long enough to reach out the nearest door/window and you're set. The water is good for the garden too!

I always turn filters off during water changes for a number of reasons. I'm always stirring up the substrate and don't want them sucking in sand, I usually clean them out while I'm doing a wc, and if you turn your back too long and siphon a little more than intended you could end up running the filter dry.
 
I do 50% water changes on my 150 all the time, and I only add 1 capful of prime, AFTER I get the temperature right, so usually about 1-3 minutes(and 5 trips back and forth to the bathroom) in to the fill.

It works fine. Note that that's about 1/3rd to 1/2 of the dosage recommended to treat the whole 150. It's worth noting, though, that when I test my tap water, chloramines barely register at all, the strip stays almost white.
 
Thanks for all the advice guys, think I'll be ordering my python here in the next few days
