Okay I'm sure this has been asked a million times and forgive my newbieness...i live in Canada and have been having a hard time finding Black or Dark substrate for my plants to be planted on... (then use white sand for my decrotive portion) this will be my first tank and I have been doing Saltwater for over a year now and figure it shouldn't be far off. I want to let my inner artist fly and really want to do it how I am envisioning it...also if I chose an inert substrate what type of fertilizers should I be looking to place in the Substrate? My vision includes plants on dark substrate and then flourish original as the underlay to create hill's etc. Any advice on soil or sand I could use instead of this 40$ a bag stuff would be awesome and in BC we don't have access to a lot of the top name brands Europe does like Scapers sand or ADA. And if we can get it it's ridiculously priced.
