Will Seachem Flourish line harm my fish?

[GrkGumby12]

I just bought a brazilian sword and 2 marimo balls for my fancy goldfish aquarium to help with nitrates a bit and for the beauty of them.. But i'm curious if using the Seachem flourish line of products (excel, comprehensive and iron) will have a negative affect on my fish.. Thanks for the help, and/or suggestions..

They're completely harmless to fish. You won't have any problems using Seachem products. What's your nitrate levels btw?

I'm about to buy some Seachem Flourish Comprehensive, too. Do you add directly to the tank, or the water before you do a water change?

Always add it directly to the tank. It never needs to be pre-dissolved. If the place you get it offers bulb pipettes you should pick up a few. They only cost a few cents and make dosing easier and more accurate, though they aren't essential.

Great. Thank you. I actually have pipettes from my AeroGarden days.

Just to note...
Excel and Marimo Balls don't get along very well. Be careful not to hit them with a strong dose. Dose Excel far away from the Marimo and/or premix it into a cup of tank water before dosing into the tank.
Your Goldfish may rip up the Marimo. Mine always have, but they leave my other plants alone.

Thanks for the tip about Marimo and Flourish. I have three Marimo balls.

Just curious as to why the marimo shouldn't be dosed with excel??

They are a type of algae. Glutaraldehyde tends to kill algae.
