in the main tank thats coming together i was told i should look into using some liquid ferts for my tank. but i will be adding shrimp (mainly as a live food) but i want them to be able to live until they either get eaten or die naturally. will a weekly does of that (4ml a bit lower than recommended) in a 55g kill off all the shrimp i put in?

is there another fert i could possibly use instead?

Goes to 11!

I have Ghost and RCS that took no notice of weekly doses of Flourish Comprehensive if that is what you mean by 'Flourish' as they make more than one liquid fert.

Umm.. It's the first word of the overview and it says 'Comprehensive' on the bottle, (http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=4652) You can quit guessing. :hmm3grin2orange:

I have used Flourish Comprehensive for many months, but only at a fraction of the label dosage, as my rhizome plants don't require much feeding, and the rooted plants get noncopper root tabs. I had RCS for many months, that were totally unaffected by these ferts. Only after I went on vacation for two weeks and the temperature in my tank shot up to 84F did I lose any, and the entire community seems to be gone. They thrived all the while I was using Flourish and the root tabs, however.

I see no danger in using Flourish Comprehensive, just be careful with the dosing. Don't go overboard.

Flourish Excel seems to be a different matter. I have read posts about certain species of fish being killed by that. I believe neons are sensitive to it.

Stick with the all-purpose Comprehensive and the needs of many of your plants will be met without harming anything else in the tank.

And -- if possible, keep your temperature stable.
