Article Comments/Critisms welcome. (If you go to the home page please don't pay any attention to the photos that aren't mine- this site started as a class assignment and the teacher didn't care where we got the photos (and time was of the essense) I will be replacing these photos with my own when i get time.
87 cents v. the cost of maracyn at what $14.00-$28.00?
How much do the totals run to replace the plants and the fish? Is it really an equitable financial trade-off?
Fish should not need a "rest" from a 60% water change unless routine water changes are spaced well more than a week apart or the volume of water changes is low with a heavy bio-load. The influencing factor that will influence the stress level encountered by fish as a result of water changes is the change in water chemistry (eg., pH, Hardness, nitrates....). Watr changes of a large volume often times result in the behavior noticed with the rainbows. Oldest trick in the breeding book used to force some activity is a large volume water change.

The article is beautifully done and well laid out.
Here is my concern. You have not figured out the conditions that allowed the BGA to take over. You have immediate results but maybe not a permanent solution. If you tried to increase the nitrate and it worked you would know that one of the condition that caused the BGA was low nitrate. If you increased oxygen flow and it helped you would know that lack of adequate circulation and oxygen contributed to the problem.
Your article approaches the use of hydrogen peroxide as a first step measure rather than a last resort. It does not encourage readers to figure out the dynamics of the tank and the factors contributing to the problem.
On another note, I know that I owe you an email. I'm incredibly tied up right now. I may be able to get something out to you next weekend.Member of Delaware Valley Aquatic Gardener's Association (www.dvaga.com)
