Partly to raise the height so I don't have to buy so much aquatic soil and partly because it's seems to be doing a decent job in my current tank.
Honestly I've been toing and forewing between lots of different combinations, and the more research I do the more I'm changing my mind. I know since I've used eco-complete it's a safe substrate for my discus.
I was looking at ADA Aqua Soil, until I read some horror stories about people fish dying when they substrate got disturbed, and I read another post saying it was just expensive dirt.
I was looking at Tropic growth substrate as a base layer covered with Tropica aquarium soil but this works out very expensive
I'm looking at Dennerle deponitmix as a base layer covered by Dennerle Scapers soil which seems to be a good price and according to there website description sounds exactly what I'm looking for, but I can find any user reviews who have used it with discus.
What I'm trying to achieve is to scape a 350 litre corner tank, for what I want to do I recon I'll need 50-60 litres of substrate so I can have a raised bank at the back of the tank. The substrate must be discus, shrimp friendly and keep the PH around 6.5. I'd prefer it didn't release ammonia when I first start the tank up so I can plant the same day.
I think I'm asking allot which is probably why I'm having such a tough time deciding what to get.
