SNOWKIWI Posted February 16, 2007 Report Share Posted February 16, 2007 I am going away for about 9 days, I don't have a problem having my tanks fed, have trained geriatric father, and he does not overfeed, My question is, will my community tanks be o.k. for an extended period, without water changes? I used to test every week, and had Nitrite readings of zero, and nitrate readings of around 20, after seven days, so now I don't bother testing! Tanks are established, and with 25% water changes on a weekly basis, all is cool. I am thinking of doing a 50% water change on each tank, the day before I go, in the hope that this will tide them through until I get back, what do you collective guys and guyesses think?

jude Posted February 16, 2007 Report Share Posted February 16, 2007 Providing the tank isn't overstocked and they aren't overfed they should be fine. My tanks, now they are stable, go for longer than that without water changes! Quote Link to comment Share on other sites More sharing options...
Wok Posted February 16, 2007 Report Share Posted February 16, 2007 I have left my tanks alone for 2 weeks. all fish were fine. Can't say the same about the fries that were in there though. Quote Link to comment Share on other sites More sharing options...
Caryl Posted February 16, 2007 Report Share Posted February 16, 2007 As one who only does water changes once every 3 or 4 months I would say they should be fine :lol: Do a water change 2 days before, so you have time to spot trouble. If the tank is mature, understocked and well planted it will be fine. If you usually do a water change once every 7 days then strectching it to 9 isn't a big difference. Make sure the filter is going well at full output. Quote Link to comment Share on other sites More sharing options...
