arixonbarnes Posted October 16, 2009 Report Share Posted October 16, 2009 There is an excellent article in the November issue of TFH on this. I thought twice weekly 50% water changes were enough but it appears that a complete water change occasionally is necessary to prevent toxicity.

Ishkabod Posted October 17, 2009 Report Share Posted October 17, 2009 WHA??????? complete changes???? How and why and once again how and why. I really want to read that article now. What is TFH? where can i find that article. Any more experienced fishkeepers out there that might have more knowlege on what might be going on with this because frankly i have no clue.

arixonbarnes Posted October 17, 2009 Author Report Share Posted October 17, 2009 Tropical Fish Hobbyist - you may be able to get a copy at your lfs. It's a 2 part series with the second part next month. Basically if you change 50% of the water once a week then you get rid of 50% of existing dissolved toxic stuff but the next time the concentration is higher and it builds even though you do 50% water changes. I expect some dissolved solids get removed via biological filtering but probably not all. If you can find the magazine it's worth the money to buy the November/09 and December/09 issues. You could also subscribe on line and I think all the articles are available to you. http://www.tfhmagazine.com/ Quote Link to comment Share on other sites More sharing options...
Vallisneria Posted October 17, 2009 Report Share Posted October 17, 2009 I've heard that problem referred to as "old tank syndrome" before. Thanks for the heads up.Sounds like and interesting article. I'll have to grab a copy. Quote Link to comment Share on other sites More sharing options...
