[90gal]

Alright, I ordered all the Co2 stuff so I'm on the right track. I now need to replace all the inert substrate. I've read tons of posts, the articles about mixing, and am now just educated enough to be dangerous.

Will there be any problem laying down 2+ inches of straight laterite and then covering that with pool sand (only for looks), or do I need to blend some eco-complete or something else in there too? It's a 90 gallon, my only surviving plants right now are swords and a few anubias, I've got Co2 setup in the mail, and about 2.5 WPG.

Thanks for the advice -
Rob

My plants have not been doing well at all, and I was told that I wouldn't have good results with inert substrate. I've been spending ridiculous amounts of money on Excel and Flourish since it's a 90 gallon, and I'd really like to avoid daily dosing. The substrate I have now is smaller pebble type gravel. I have extremely hard water with a PH of 8.4 from the tap.

Do you think if I did the same process as that article you linked above that I'd be better off?
