Hi there. I've been keeping reef tanks for quite awhile, and always had a small 20g High planted tank on the side which I've not paid much attention to until lately, where I've added CO2 and upped the light to a 65W CF bulb in hopes of growing something more than java ferns.

My problem is my substrate is... suboptimal (or so I think). Its a combination of a little bit of fluorite and normal aquarium pea sized gravel, which makes planting (especially small ground cover like plants) a giant pain as the substrate size is simply way too big.

What would be your suggestion on replacing the substrate? Sand? Go for pure fluorite? Eco-complete?

I was thinking of doing the tank in thirds over three to five weeks, with the realization that I will never totally eliminate the normal aquarium gravel with that method. I could try sieveing out the aquarium gravel, but need to find the perfect size sieve. I'd prefer not to do a total tear down, as I don't have a home for anything else in there (rasboras aren't salt water compatible like sailfin mollys :))

:help:

Now just to pick the color ;)

Any thoughts on substrate replacement policy? If I move to ADA soil, I obviously want to dump as much of the original as possible, but probably best not to do it all at once.

Amazonia = black/dark.

Soak the ADA AS for a week or so before you do it.

I would just try to keep as much of the old water as possible and all your filter media. Other than that, I'd remove all of the original and then use the soaked ADA AS.

Filter is an oversized Fluval, so plenty of bio filtration to back up substrate removal.

Now the question is amazonia or malaya (the light one). Time to find some pictures I guess ;)

Thanks for all of your fast help!
