15 pounds of flourite enough for a 20 gallon?

Hi guys! I was just wondering if 15 lbs of flourite was enough for a 12 gallon high ? I wanted to add a gallon of playsand over that, i relize it will sink and be mixed up eventually but it's just for looks and to help the HC get established. I believe the flourite will be 1.5 inches and the sand should (hopefully) bring it up to 1.75 inches. This is still too little? I have a feeling it is I could add a half in of my existing substrate (schultz which I had and it's ugly and lighweight) or add a half inch of sand and mix it up with the 1.5 inches flourite and add a gallon of playsand over that. It's only 2 inches and it's mostly flourite so i don't expect anaerobic areas or compaction. I'd rather go the second route but i figured i'd ask.


Will replacing my existing substrate be a huge issue if I do the water changes required? I'm moving from a 10 to a 20 high and will be setting it up tomorrow. All I have is one otto and a bunch (no more than 30) cherry shrimp. I hardly ever feed.


I kind of need answers tonight because the paint will be dry tomorrow on the new tank, all the plants are in a bucket with lights and co2, the rocks are out, and the tank is still leaking after lowering the water by 4-5 inches.

I had to use two bags to get a good depth in my 20H. I even mixed in a little shultz aquatic plant soil, the burnt orange colored stuff. You can't distinguish between the flourite and shultz after it is mixed together and put into the tank.

oh wow 2 bags huh?

Okay... well then how about an inch of the schults (auctually it's probably 2/1 schults/sand) with 1.5 inches of laterite overthat and a gallon of sand over that?

Laterite is not supposed to be a substrate. It's a substrate additive. If you have a bag of Flourite just mix it with a coarse sand/fine gravel of the same approximate grain size.

I used all the old substrate and mixed it up with flourite. Probably 10 pouds profile, 15 pounds flourite, and 5 pounds sand.

You can't tell at all!
