Hi
I’m setting up a new planted tank using a 2cm layer of Dennerle’s Deponit substrate topped by a 5cm layer of gravel (all straightforward so far) and would like have an area of sand for corys approx 2cm deep. To keep the Deponit/Gravel separate from the sand I’m planning to use a strip of acrylic bent to shape and siliconed to the tank bottom. The dilemma is how to raise the sand substrate by +/- 3cm safely to blend/level its top with that of the gravel’s.
I’ve considered and discarded a number of options: polystyrene (floats, breaks up, safety?), slate tiles or glass (heavy, difficult to shape), “egg crate” (anaerobic pockets) and would appreciate any alternative suggestions from the forum.
Thanks
