When I setup my 75 gal tank 3 years ago, I did not put enough amount, which I learned later from the various sources, at least 3 inches of depth needed. I planted water sprite and wisteria but they did not grow tall as I expected although I use 50% Flourite (mixed with other substrate). The height of tank is 18" but the plants I have now never grow more than 10 inches. I use Whisper 5 outside filter, no CO2, water change 20-30% per week. I keep many guppies and a few cori cats. My question here is whether or not if it will be possible adding more substrate to make up the required depth, which may affect the growth of the plants. I am fairely beginner for the planted tank and all other people here are very experienced so I wanted to obtain some advises. I have been tempted to redo my tank from scratch (I don't know what I would do with my lovely guppies though). My intention sounds really stupid but if somebody can give me a good advise, I will appreciate your opinion or instruction. Thanks.

What kind of lighting you use?

I don't think the substrate is your problem. Water sprite will grow floating as will the wisteria. If your tank conditions are good either one could cover the surface of your tank in a couple of weeks starting with a couple of stems.

Start with lighting. How much light do you have? Do you know your nitrate and phosphate levels?

Well, the lighting may be a problem. I use a standard Perfecto double strip lighting, 48" (40W x2) and 36" (15W x2). If I use a basic formula, 3W per gallon, my setup is way too low for the planted tank. As I mentioned, I learned a lot after researching more information. This is another issue I have to work on.

Actually your tank is at 1.4 watts per gallon. I will take the leap here and say your lighting is your biggest problem.

You might want to head over to and get a retro fit kit and get more light over the tank. You should really shoot for a minimum of 150 watts of light and unless you want to add CO2 no more than about 180 watts.

Thank you for your suggestion. Even new years day I get a response and it makes me feel better to know somebody cares about other's problem. Well, it seems that I will have to start doing something on the lighting system first instead of considering more substrate. I checked your site and others, and found I definately need more wattages than what I have. Even if I add another 48" double strip light housing, it will only make it 160W (currently I have only 110W), so I need a retro fit kit as you suggest. Because of my limited budget, this project will take a little longer but I will implement the new system. If you have any other suggestions regarding a suitable setup for my tank with a reasonable price range, that will help me out a lot. Thanks again.
