Mineralized Top Soil capped with Pool Filter Sand and Eco Complete
I have a 40 Breeder I've been mineralizing top soil for. I have some Eco Complete I was going to cap it with, but I'm increasing liking the sand beach look in the front of the tank and thinking the HC and DHG I'd like to grow would do better in the sand. Would the steam plants benefit enough from the Eco Complete cap as opposed to sand to warrant trying to separate the two or should I just roll with a PFS cap across the whole tank? If I do both caps, will they eventually mix in together if I don't seperate them with hardscape or some sort of a guard? I'm fine with a transitional area where the two gradually mix, and this would be where the steams end and the ground cover starts so it'd be covered, but I'd like the beach to stay clean.
