Did I use the wrong sand as a dirt cap?
Hello, newbie here. I have had fish tanks forever, have had live plants in them, but didn’t get into it any more than just sticking some beginner/easy plants in there. I did elaborate planted terrariums for a long time for frogs. Now I recently became interested in the really fancy aqua-scaping I’ve been seeing with dense plants and low-tech. I started watching some videos and had been wanting to re-do my 15 gal long, so I followed one of the videos and took my tank apart and added organic sifted dirt on the bottom (about and inch to inch and a half) and then capped it with the sand I already had in that tank (another inch...deeper in the back) and put it all back together. Since the tank was already established, only thing new was the dirt underneath, I was able to add the fish back and they are fine two weeks later. It is not super heavily planted yet as I didn’t have money for that, so I’m just waiting for things to spread. I do still have a filter going, but the flow is blocked by a decoration cause I have a betta in there and they don’t swim well with lots of flow. I also got a much better LED light for it and the plants seem to like it. I didn’t lose any fish, they didn’t even seem bothered by the change, so assuming the tank didn’t have to cycle since I re-used everything in it. In fact they seam healthier and are now doing breeding behaviors. (Fish are 1 female betta, 7 galaxy rasboras, 5 ember tetras, tons of ramshorn snails.)
BUT I’m concerned anyway! LOL The more research I do, the more I’m seeing that the sand I used might be bad? I used Carib Sea Super Naturals tan colored sand from the pet store. I rinsed it a ton, it made the water slightly cloudy for maybe a day, but then was fine. But now I’m seeing people saying it’s too fine and roots can’t go through it and air pockets will get stuck in the dirt and become toxic, etc....I haven’t noticed an issue, but will I later? I have poked it and air bubbles came up. Plants are growing...only ones that died were dwarf hair grass, but I suspect it was because the light isn’t full strength in the very front of the tank, so I took it out and put it in another tank where it’s in the light. Other plants have grown. But now I’m concerned that the sand is too compact and is just sealing off the dirt instead of it providing for the plants like it’s supposed to. What do you guys think? Am I being paranoid since I’m not seeing issues, or is this not good for the future?
