Theplatymaster Posted February 3 Share Posted February 3 This has probably been tested before, im trying myself. The preface to this project was mostly watching MDfishtanks videos, how most of his tanks use a capped nutrient layer, and i thought id test it. But using dirt wasnt really a good option(Suprising i know right). However i remembered that i have a big bag of potting soil in the garage, and its similar to dirt so hence my experiments.(Also i have some crypts i want to grow big) Container:Pretzel Container Water Volume: ? Lighting: Ambient room light, and light from the window next to the container Substrate: Potting Soil Capped with Sand Plants for testing: I have Crypts that i will be using in this test, mostly because i want them to grow bigger, hence the potting soil idea. But i will also be testing Java Fern, and Elodea. Note: This is not a very scientific approach, i have no control, take this with a grain of aquarium salt. Im just trying to grow crypts bigger, and posting it here. Hypothesis: If potting soil capped with sand is used for Cryptocorynes Then they will grow faster. Initial water testing results, (Im looking only for potential nutrients): Ammonia:0ppm Nitrite:0ppm Nitrate:0ppm. Nothing released into the water column (yet). When i was filling it up, a tiny bit of potting soil got uncovered so there is a tiny bit floating around, most of it is under sand though. Time to add plants: As i said this is not a super good experiment. The basket with the crypts was burried to the bottom, with the top of the basket not covered so the crypts can utilize the soil. Elodea/anarchis, was simply planted in the sand, and the rock with java fern, was placed on the sand. If i was better at this id have like 7 of these setup for controls, but i dont ill see what happens. Here is a picture of the jar after planting: photography was hard, the water was cloudy from the sand. 2 Link to comment Share on other sites More sharing options...
