Exclamation Science Project Help

First of all, this is my first post, so let me introduce myself,im Carlos.
and am in need of help in a science proj., as you can tell

I'm doing a project in which i will test the effects of pharmaceuticals(medicine) on aquatic plants

Now i need to know all of the following:

What plants are better for me to use[im on a budget(the cheaper the better, but i like quality, too)]
I live in North Pasadena,east of Houston, TX so if you know a store,that will help out a lot.
I don't really like the idea of ordering them online

I don't know what types of pharmaceuticals i will use yet,but if you know something , please advise me

I'm going to use 2 tanks(1.5 gallons each) they are in the shape of a vertical rectangular prism,
and i believe they're tetra care but this will be my first experience with live aquatic plants,
but not with tanks and thats all i can think of for now

THANKS FOR YOUR HELP...

You picked a difficult project! What are the dimensions of those 1.5 gallon tanks, how tall, how wide - side to side, and what is the distance front to back? To grow most aquatic plants you need a substrate, which can be ordinary swimming pool filter sand, you need light, which can be a desk lamp with a spiral power saver fluorescent bulb, for each tank, some appropriate aquatic plant fertilizers, and the right plants. You can get a pair of cheap desk lamps from any number of places, so that is easy. I can see you needing to spend about $20 for the two lamps, about $5 for the two light bulbs, possibly nothing for the filter sand (you can also use somewhat coarse play sand). For fertilizers, there may be an APC member living near you who could give or sell you the small amount you would need, for almost nothing.

The best plants might be Egeria densa, also known as Anacharis, see https://www.aquaticplantcentral.com/f...us&spec=Egeria for information about it. Most local fish stores sell that if they sell any aquatic plants at all, and it is cheap.

Now for the "drugs". That is a hard one. The only "drug" we use is erethromycin, which is an antibiotic that will kill most harmful fish bacteria, green water algae, and, I believe, Ich, a parasite on fish. Unless you can somehow cause a problem to occur in the two tanks, this isn't going to work. So, I suggest just dosing one tank with aspirin. I have no idea what that will do, if anything, but that would be the fun part of the project.

You would need to let the two tanks grow their plants for a month or so, to get them growing good, and to be sure you can keep the two tanks identical when they should be identical. Then you could add one aspirin tablet to one tank and observe the tanks for another month.

thanks for the information on the aquatic plant ill keep that in mind,
Also, can you send me or post ,more information on the substrate I might have to use?I'm thinking to use the plant you mentioned.
I'm putting in some picture illustrating the tanks;if that will help to y'all

I dont feel like opening the wrapping around the tank but for now it at least fives you an idea of what im working with





It already comes with an LED light and filter ,and
ill discuss the pharmaceuticals with my instructor

The problem is that the light is not intense enough to grow any plant except moss, and grow it well enough to see any difference a drug would make. Because it is so deep, compared to the size of the tank, and the light is so high above the water, you will have very little light that reaches the bottom of the tank.

You might be able to keep anubias plants alive in it, or mosses, but they wouldn't grow enough for your test to work. I suggest you read https://www.aquaticplantcentral.com/f...90-basics.html and https://www.aquaticplantcentral.com/f...parts-1-a.html to learn more about planted tanks.

Well I'm sure that i can get something worked out with the light,
that wont be a problem.

But, assuming i buy some Anacharis, what substrate should i use?
and why would the aquatic plant fertilizer be necassery?
and what brand should i buy,if i needed it?

I hope im not giving you any trouble, and i do appreciate
the help your giving me.

You aren't giving any of us any trouble, since we are here because we enjoy doing this. Right now, you need to do some research, so you will know enough about growing aquatic plants in an aquarium to be able to do your project. That is why I suggested the two threads in this forum. Once you do that you will have most of your questions answered and can make some good decisions about how to proceed.

It won't work for us to tell you each step to take, because you won't understand why we suggest what we do. You just need to spend an hour or two reading, and you will find this to be much more interesting.

ok, i see what you mean, a good project is a good researched project.

Well off to my reading....

on the ben b's basics , is there like a version where i can copy and paste it? i'll most likely
add it on to my research sources.

Another plant that is easy to grow is Hornwort, Ceratophyllum demersum. It is mostly a floating plant but I and others have got it stuck in the gravel. There are 2 types you can see at plantgeek.net.

Are you going to do a el natural tank style? It doesn't use ferts. There is a section on it at this forum.

Here is an interest article on how to grow plants cheap. http://home.infinet.net/teban/how-to.html
I read it after I got my tank set up. If I tear it down I will be doing this.

If you buy plants at petsmart beware that not all of the plants are true aquatic plants and will die within a year.
I have seen small tanks like that with desk lamps over them. That is a desk lamp with a flouresant tube. You ought to look at the nano tanks in the aquascaping section. It will get you hooked on planted aquariums.

When I want to copy and paste for my use, I just highlight the text on the screen, while reading, copy it and paste it on a word processor page. I do that with each "page" of text as I scroll down reading it. Then I edit what I pasted to make it fit what I wanted it for. Since you aren't selling this, or even taking credit for writing it, I can't see how anyone here could object.

Dawntwister's suggestions are good ones. If you used hornwart as the plant you wouldn't need to concern yourself with a substrate. It grows fine just floating in the water. That makes the whole project easier to do and easier to evaluate.

Thanks , but i want to recreate a freshwater environment (minus the fish,and amphibians) and a planted aquatic plant will have a better image.
