Fertilizers that are safe for my fish?
 
Hello I have a twenty nine gallon tank with some various plants. I was wonder what, if any, plant fertilizer will be good with my tank. My tank houses, or will be housing: guppies, celestial pearl danios, marbled crayfish, cherry shrimp, and a few onion shrimp.

I think I recall reading some where that copper compounds were bad for one of those guys listed, not real sure.

Any information will be useful. Thanks.

I don't buy pre-made aquarium fertilizer solutions because I prefer to mix my own, but I don't see why they would include copper. I'm pretty sure the manufacturers list the ingredients in their ferts so you can check out some of the more popular ones to double check (I believe API and Seachem make some).

I believe it was Seachem that I was looking at on Amazon. Their first or second result lists a copper compound.

From a page on Seachem's Flourish "Copper 0.0001%"

I know that seems like a very trivial number but I'm just trying to double check so I don't kill off or sterilize my fish.

Oh, gotcha. I did a brief google on copper contained in typical aquarium ferts and most of what I found says that the trivial amount that these ferts contained shouldn't harm shrimp, but some people still claim that it does. For all we know, they may have overdosed or the copper could have come from a different source and they assumed it was the ferts. Sorry I couldn't be much help but I'm sure someone else here has more knowledge on this topic.

Thanks for that.

If you were to buy a fertilizer for java moss, anacharis, mexican oak leaf, java fern, and wisteria, what would you buy?

Is there any particular reason why you're wanting to dose ferts? What lights are you using? Have you been having algae problems? Are any of your plants showing symptoms of nutrient deficiency? Those are all low-light plants that should be fine without ferts in a properly stocked tank. I didn't even start dosing ferts until my plants really took off to the point that I was getting a zero nitrate reading on my liquid API test kit (I had soil as a substrate so they were able to survive off of that for quite a while). And since I have a 90g (and I prefer to know exactly what I'm putting in my tank) I opted to buy dry ferts and mix myself, so I'm not very familiar with the pre-made solutions, sorry.

If it was me I would buy Seachems Flourish comprehensive and dose like once a week and see how things go.

Flourish Comprehensive if used as directed, will not harm invert's.
Used it for a while with cherry shrimp before I grew tired of paying for product largely comprised of water.
Switched to CSM+B (aquarium fertilizer.com) cheaper,last's much longer, and it contain's a tiny bit more copper than the Flourish, but it too would have to be overdosed grossly before creating harm to shrimp's.(judging from my expierience with shrimp's)
Both are safe so long as you don't overdose.

I've been using Flourish for a while now, and still on the same bottle. Have several of the plants you mention and all have been growing great. For about $13 on Amazon you can get a 500ml bottle. Considering I only use 5ml every dose for a 55g, thats a year and a half of dosing twice a week or almost two years of once a week. Store it in the fridge to keep it fresh, and it's a cheap and easy fertizer solution for smaller tanks. If you get up to larger tanks (75g+), Thats when I would look into dry ferts.
