I currently have 3bags of Flourite, I had planned to mix this with plain gravel but have decided to go straight with a better plant substrate than mixing with the gravel. How many more bags of Flourite would I need for a standard 55G tank? Also Ive heard alot of good things out Eco-Complete has anyone ever mixed that with Flourite? #1 · Nov 21, 2008 I currently have 3bags of Flourite, I had planned to mix this with plain gravel but have decided to go straight with a better plant substrate than mixing with the gravel.

Sort by Oldest first Oldest first Newest first Most reactions #2 · Nov 21, 2008 I think that the general rule is 1.5lbs per gallon. you want it to slope towards the back with it being about 3-4" deep at the back with 2" at least in the front of the tank. good luck! BTW welcome to the forum

#3 · Nov 21, 2008 I was planning on having it sloped up in the back corners at 3-4"...slope it down in the front to 2" and then slope it in the middle to about 2"

I have a nice centerpiece of wood to go in the center

How do you think mixing in 2 bags of eco-complete would go? I want it to stay mixed and not eventually separate into a layer of one and a layer of another. #4 · Nov 21, 2008 the grain size will naturally seperate depending on the differences in the substrate you use #5 · Nov 21, 2008 if you have eco and flourite it shouldn't seperate too much.. but if you have say.. sand and flourite.. it will do that over time. I agree with Tommy^ #6 · Nov 22, 2008 Hi The new Seachem site has many calculators. Here is the one for regular Flourite substrate. It is at the bottom of the page. http://www.seachem.com/Products/product_pages/Flourite.html #7 · Nov 22, 2008 Awesome

Thank you. It said that I only require 4 bags...alot less than I figured as thats only 60lbs of substrate for a 55G tank to get an average depth of 3". I wonder why it takes so little to make such a deep substrate...all I can figure is this stuff must not compact down like gravel or sand. #8 · Nov 22, 2008 I once used 400 cubic inches per bag for my calculations of regular Flourite (48" x 13" x 3" ÷ 400 cubic inches = 4.68 bags). Here is this site's substrate calculator: http://www.plantedtank.net/substratecalculator.html So, 4 or 5 bags will be enough for a 55g. #9 · Nov 22, 2008 Again...thank you for all your help. Looks like Im in the market for another bag....guess Ill get on making another order for one
