Build a Better Aquarium Plant

Aquarium decorations are ridiculously expensive.  In this Instructable, I use hydraulic cement and some scraps of aquarium gravel to make a base and turn a cheap-o aquarium plant into a better plant that would cost a lot more at the store.

1. 1 cheap-o aquarium plant
2. a few handfuls of aquarium gravel (optional)
3. hydraulic cement
4. a small tub to mix cement in
5. latex gloves
6. plastic wrap to protect your work surface

COSTS:

• The plant in this Instructable was $1.99 plus tax. (I also got a pack of four large and small plants for $10.99, which I used for a couple of larger arrangements.)
• The gravel was free in my case because I have lots on hand.
• Where I live you can get a whole 20lb container of hydraulic cement for $12.00. I used about a pound for this project, so $0.60 worth of cement.
• I used a recycled tub to mix cement in, so it was free in this case.
• Where I live a box of 100 latex gloves costs $8.00 at the hardware store, so I used $0.16 worth of gloves.
• The cost of the plastic wrap is negligible in this case.

Grand total of 1.99 + .60 + .16 + 8% tax  = $2.97 approximately.  Comparable plants at my pet store cost at least $8 and up. 


WARNING: DO NOT RINSE HYDRAULIC CEMENT DOWN THE DRAIN!  Even just small amounts will collect down there and harden a little bit at a time until the plumbing is completely ruined.

• To protect my plumbing, I use disposable gloves to work with the cement.  If I get any of it on my skin, I wipe off all that I can using a paper towel.  Then, I wait for whatever is left on my hands to dry completely and brush off all that I can remove that way.  Finally after I've removed every bit that is possible, I wash my hands in a utility sink with a deep trap so if it ever does collect in there, replacing the pipe will not be too difficult or expensive. 

How to mix hydraulic cement: https://www.instructables.com/id/How-to-mix-hydraulic-cement-for-sculpting/

Approximately match the size of the plastic plant base

Put the cement on top of the rocks as two piles - see photo

Add water if necessary to work the cement around the ends of the base

BE CAREFUL TO LEAVE THE CENTRAL AREA CLEAR OF CEMENT

You can work quickly and embed some gravel into the existing cement or you can mix another small batch and use it to build up the edges some more and embed the gravel that way

Before the cement is completely hard, use an old toothbrush and gloved hands to clean the loose cement off of the aquarium gravel.  It's important to be gentle, or the whole thing can fall apart at this point.  However, it will be much more difficult to clean it up and expose the gravel if you wait until the cement hardens all the way.

In the photos you can see that I also gently broke away the sharp edges around the bottom perimeter.

If you left the center area clear of cement, the plant will snap right into place.

Wait for the cement to harden some more, then give it a last brush off and hose-down before putting it into the aquarium. 

WARNING: DO NOT RINSE HYDRAULIC CEMENT DOWN THE DRAIN!  I keep saying it because it's worth saying.
