I'll go with the CaribSea Sand. Some variation of it anyways. While we're on the topic......I'm planning on getting some fake plants.....I remember in the past I had a tough time keeping the plants from floating up. Any tips on how to keep them anchored to the sand? Thanks again in advance
I use Quikrete Fine Grain sand. It's completely inert silica and does not need to be washed before hand. It also has such fine particles that they settle instantly. You just have to be careful adding water to the tank because you'll create a sandstorm if you pour too fast. Best part: it's $4 for a 50 pound bag at Home Depot or Lowes. It looks like white beach sand. I've been using it for my planted tanks for over a year with no negative effects.
You can buy plant weights, just make sure you know what they're made of so you don't have metal corroding in your tank.
I use river stones as weights. If the plant already has a base, you can use aquarium silicone to glue a rock to it. If you don't want the plant to be any taller than it already is, glue a rock to the side of the base, rather than setting the base on top of the rock and gluing it stacked. If the plant doesn't have a base, here's what I do: I get a river stone, wrap it in fishing line several times, knot the line securely to the rock, and then spread a thin layer of aquarium cement along the knot and fishing line on one side so it doesn't slip off. I cut the excess line after the glue dries. You can try just wrapping the rock without gluing, but it may slip loose over time.
Here's a pic of what I mean. If you want to re-use the rock, tie a little bead on it like I did. Then you can thread string through the bead and tie plants to it as many times as you want. I use these rocks in a bare-bottom tank, so I used a tiny clear bead. If you're going to bury the anchor rock in gravel, you might as well use a bigger bead. It's easier to run string through a bigger bead.
Sorry, my instructions were confusing. If you don't tie a bead on, you will of course need to NOT cut the thread ends after the glue dries. If you cut the threads off, you won't have anything to tie to the plant!
That's for salt water tanks... You should return it.
Your fish won't really tolerate that, they'll feel sick.
I was afraid of that. Yea, I just noticed that when I got home and figured I'd better ask before I started setting up. I just wasn't sure if it'd be okay since it doesn't actually include any salt etc.
