  1. Hi Sudeep,
    Great article! I am an aquarium enthusiast and until now I was into keeping Discus. I always thought that it was very difficult to maintain planted aquarium but now thanks to your article that I have managed to start up a planted aquarium with much ease. Thanks again for the great info put together.

  2. Thanks for the low tech planted tank article, it was great!

    I’m a reef guy switching to a low tech planted tank. It’s 150g (72″Longx18Widex26″Tall). Because it’s 26″ tall, what would be the recommended lighting setup? I already have 3x 175w 13K halides installed and would love to use them, but will replace them if needed. I could even use them in sequence (one one at a time for 2hrs each, then all three on the last 4hrs?).

    What do you think?



  3. First I’d like to thank you for your description on setting up a low tech aquarium. But I’m a little unsure on wether or not I have the correct lighting for mine. Here’s my info..

    I currently have a 40gal tank 36Lx15dx17t
    Lights: duel T5 39w 6700k per.
    Can you tell me if this is to much or to little?
    And thank you in advance

  4. I am very interested in starting up a low tech tank, but I don’t want to be disturbing the substrate and plants very often. You mentioned that you should start out with fast growing plants then phase them out as you get going. I don’t really want to do that (buying plants I’m just going to get rid of anyway, and disturbing the substrate are my main issues) Are there any plants you would reccomend that I could start with and keep? I don’t mind starting slow.
    Also, what is the smallest tank you would reccomend for a planted tank?

  5. How much substrate do i need? And how deep should I have my sand or gravel bed on top of the substrate in a 36 gallon tank. I’m new at aquariums. Thanks for the help.

  6. Love the article, guess you get that a lot, lol. I’ve basically setup a 55gal with a sump and worried about it not getting enough light because of the height of the tank. I think it’s about 22 inches high, I have 2x20W T8’s and 2xT5’s.

  7. Many thanks your articles, very helpful. I have a problem and seek your advice.
    Tank is a fluval edge 23l to which I have added two 5w 6500k LED lights,(13.5in total). Lights on timer 10 hrs / day and planted with java fern broad and small leaf and three small Anubis.
    One male beta, 5 cherry barbs and three ottos inhabit.
    Weekly 25% water changes at which time I add 0.25 of tetramin plant food. Also keep indian almond leaf in tank but change When starts to breakdown.
    Started tank 11 months ago and water conditions never change, 0 ammonia and nitrite, nitrate 0.25 to trace but tap water shows 20. Only tested for phosphate recently and tank between 0.5 and 1. Tap water 0.5.
    Plant was doing great, multiplying and thickenning and I was growing baccoppa Carolina profusely and having to cut back regularly.
    Suddenly I had BBA and feather algea on plants and the broadleaf java fern suffered and started showing brown patches.
    nothing has changed accept I think I overdone the pruning on the baccoppa and that is when the algea started to show. I replanted but it has all died back.
    That when I added the Anubis.
    I have been dosing seachem excel and upped the dosing of the tetramin for the last week.
    I really am at a loss and would welcome any advise. I have tried to maintain a natural tank and avoid adding chemicals. I guess I am asking a lot of such a small tank. The only advise I get from shops is add chemicals to get rid of algea but this is not the route I want to go down and in all honesty I am unhappy adding the seachem.
    Anyhow, if you have any wonder cures l would welcome.
    If you tell me how to post them I can send some photos.
    Thank you for your kind attention

  8. Hey! I’m just looking into possibly changing my tank over to a planted tank, I have a 36G bow front tank. It came with a 17W T8 24 inch light and some say that that’s not enough lighting. I would like a carpet plant, and I have no idea what else right now. Just trying to figure out the cost to switch over. Thanks!

  9. Just wondering why you specifically mention in the article that incandescant lights should NOT be used? thanks

    1. Apologies for the super late reply. The reason to avoid incandescent lights is simply because they produce far too much heat in comparison to light and are extremely inefficient in providing the requisite amount of light needed for growing aquatic plants. While they can work for some low-tech plants, I just wouldn’t recommend using them as they are also going to heat up the water surface substantially.

  10. Hi!

    Thanks for taking the time & effort to simplify the process of setting up a planted aquarium.

    I live in southern India and I’m an absolute novice. I don’t know where to procure the substrate from & also where to procure these plants from. Would you recommend any place where all these are available in southern India? I’m not sure if my local fish store store stocks these.

    Also, are there any alternatives to those that you have mentioned?


  11. sir i have two feet fish tank and i know how to make fertilizer fish tank and soil and sand andco2 and light please replay fast help me thank you rahul maurya

  12. hi, thanks for the information.
    Can you suggest , how to use a internal filter for a planted setup? Is it possible?
    Is there any good and cost effective external filter?

    Please suggest


  13. Dear Sudeep!
    Just stared my new aquarium basad upon your article which is very usefull, thank you for it!
    I have a question straight forward:
    this is the second day since the start but the water is still a bit cloudy (all subtrate and media was washed, also bacteria was added, carbon filter media was added 12hours ago).
    -Do you recommend water change at this state or i should wait more?

    You can find my blog and pics here.

  14. Dear Sudeep!

    it’s been 4 days i started the aquarium, but it’s still a bit cloudy (dusty).
    do you recommend water change or it would ruin the method? :)

  15. Now that you have an idea of the basics necessary to set up a planted aquarium, you might be wondering about aquascaping the tank. Next month, I will offer aquascaping tips, a selection of plants that are appropriate for beginners, a how-to guide for placing hardscape items, and more to make your tank look as good as a pro s.

  20. Great article! In the substrate section, you had mentioned that any type of porous substrate with a high CEC is suitable. Does pool filter sand (coarse sand) work?

  21. Hi,

    A very interesting article, thanks very much for sharing!

    I’d like to know a little more about your 10gal low-tech tank:

    From the picture, there doesn’t seem to be a large diversity of plant types (maybe 5 or 6). Presumably this was deliberate to keep it as simple as possible?
    Could you kindly list the plants in there for me please? I’m pretty new to planting and not so good at recognising them by sight.

    Thanks again,

  22. Hello,

    I’ve been toying with planted tanks for years and haven’t had much success. I’d like to try your low-tech, non-CO2 method, but, in Canada, it is hard to by Potassium Nitrate and Potassium Mono Phosphate. Do you have a substitute method, say, buy using Seachem products?


  23. Hello,

    New to the hobby but not to the more technical aspects of fertilizing plants. I really enjoyed your article and found it very useful. I do have a question though. If I were using your recommendations for fertilizing the tank AND I were using Flourish products for NO3, PO4, K, Ca, Mg, and Fe I would need something like 12ml Flourish Nitrogen, 55ml Flourish Phosphorus, 6ml of Flourish Potassium and 1/2 tsp of Equilibrium for each dosing (2x week) on my 40gal tank. I did the calculations on APC’s Fertilator. Am I being an airhead and I totally missed a key piece of information because that seems like a huge amount of fertilizer per week? Is this why you mention buying in bulk? Thanks!

    1. I should have specified that I was trying to match your recommendations for ppm not tsp using Flourish products. You stated that there should be 5.27 ppm NO3, 1.61 ppm PO4, 7.41 ppm K (adding 3.43, 3.32 and 0.66), 1.42 Ca, 0.42 ppm Mg, and 0.02 ppm Fe. Sorry for the confusion.

  24. I think I have been convinced I know enough to successfully do a planted tank now. It will only be a 10 gallon tank but it will be awesome. What plants do you have in the tank on top of page


  25. Hi I do have a low tech excel dosed planted tank .
    Tank dimensions 75cm×30cm×60cm . Filter sunsun hob 702
    and using flourish and plant magic biweekly .
    Lighting 6 hours a day by sunsun sl 800 led .
    Water change weekly 30 percent .
    I can observe that my plants were growing well and I do find browish dots on my plants leaves which totally spoils my tank look . I cannot find the reason for that . Please suggest ur opion on this
    Tank complement :
    1 pair cardinal tetra
    2 pair of rainbow
    3 pair of cheery barb
    3 pair 0f rummy nose
    1 pair of cory cat
    1 pair of seamease algae eater
    And I do use aeration motor but kept to minimum 24 hours a day .
    My serious doubts for that brown dots on my plant leaves were
    1) because of too much oxygen as I am using aeration 24 hours
    2 ) maybe bcoz of sunsun sl 800 led
    And not using t5 bulb ..
    Kindly advise
