Al, I only have this problem in the winter when I have to use more warm water, in the summer time it goes away. For whatever it's worth..I tried a couple of experiments and it seems that if the water you're replacing is on the warm side you have more bubbles build-up, when it's cooler I have no bubbles at all. Whether this is a coincident or there's some scientific explanation I couldn't tell you!.. Lastly, I never had any fish suffer from it. good luck sal ----- Original Message ----- From: Al Smith <alsmith1@mindspring.com> To: <apisto@listbox.com> Sent: Monday, June 18, 2001 4:06 PM Subject: water changes and bubbles..... > When I do a water change ...the tank seems to fill with tiny bubbles and > they cling to plants and sides of tanks..I put a nozzle on the end simular > to a watering can nozzle to try to difuse the water and no help.. reason I > am worried as I read somewhere that this can harm the fish as the bubbles > getting in there gills causing some type of an embilizem...It takes about an > hour or so for they bubbles to disapate...this just started since spring > time..never does it it the winter months...Is there any way to stop the > formatiom of these bubbles and also will these really hurt the fish..oh my > watersupply is well water..if that helps ....and I also see bubbles collect > on the inside of the water hose that I fill tanks with...water paramaters > from tap...ph 6.6....3 dh... > > AL > > > > ------------------------------------------------------------------------- > This is the apistogramma mailing list, apisto@listbox.com. > For instructions on how to subscribe or unsubscribe or get help, > email apisto-request@listbox.com. > Search http://www.digital.com for "Apistogramma Mailing List Archives"! ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
