Help with sand substrate

I am fairly new to the fishkeeping world, so I am still in the process of learning a great deal about fish and plant care. I set up a new 30g tank about four days ago and added 25lb of CaribSea Super Naturals sand



I added a few ferns, some mondo grass, umbrella plants, and a couple mystery plants. Then I started looking for info on keeping plants in sand substrates and I haven't found anything very reassuring. Is it impossible for plants to thrive in this type of substrate? Are there any pointers anyone can give me? I'd prefer not to change substrates, but if I have to I'd really like to keep a white sand substrate like I have, if at all possible. Any pointers would be appreciated!

I'm curious about this myself. I've heard of using soil and capping with sand. I wonder how pure sand works.

Seeing as it's not nutrient rich substrate, you might consider looking into/researching fertilizer pellets that you can stuff into the sand and a fert regime for the water column. Beyond that, I'm just as much a Newb and anyone!!

I'm setting up a tank now and looked into similar options. I've decided to either put sand over my Amazonia substrate or have a partitioned tank. Two options that may have come late for you. Good luck!

Well, what a read a few days ago was that sand doesn't allow for nutrients or gases from above to reach the roots that are bellow the sand. I think someone said that I should poke the sand every once in awhile to help gases get to the roots, or something to that effect. But then I also read somewhere else that I shouldn't disturb the sand because gases from below the sand produced by the anaerobic bacteria could kill all the fish in the tank if they are released. So, I'm looking for a little direction because I have all this information coming from all over and I don't know what I really should be doing D:

I completely understand. I'm in a very similar spot. Good luck and I look forward to seeing other responses. I'll do some research as well and see if I can post links to what I find.

Here's just a few to start. I'm looking for more. The second one might be more on point. The first covers sand ON a nutrient rich soil.

Very brief bout of searching. Much more info there. Can't talk more. I've said too much.

Thanks for looking into that for me

I'm still not completely confident with how to tackle my situation because I really don't want to mix my sand with planting gravel, like the person did in the first link. I think it looks kind of strange..

Has anyone had any experience with the Seachem Flourish Tabs?

Tablet fertilizers are good.

Mondo Grass is not an under water plant. It will die slowly, not grow.
There are not many ferns that are OK under water, and the few that are should not be planted in the substrate. Java Fern and Bolbitis.
If you can post pictures of the mystery plants, and the umbrella plant perhaps someone can ID them.

Many house plants will barely survive under water for a while, and there are stores that will sell them as aquarium plants. :-(

As long as the sand is not too deep there should not be problems with anaerobic pockets forming. Under 2" is good for most grades of sand.

Check out my sig. I didn't use that sand. I used silica sand from home depot. Doesn't look that bad. Its whiter than the sand at the lfs.

I was thinking of doing exactly what you did with the plant gravel but I really wasn't digging the idea of spending another $20 on substrate. I already paid $25 on my sand from Petsmart D: I may just have to suck it up. I guess it's better paying $20 more on substrate than buying new plants after mine die.

Ive read that sand under 2" prevents the dead zones but shouldn't plants be planted in at least 3" of substrate??
