Hello, from my other posts of learning my tank has been running smooth fish wise, but I need help with plants. I can't grow anything. It was my plan from the beginning to have simple plants and slowly replace the fake ornaments and plants in my tank to make is lush and filled, but 6+ months in and I only spend money on murdering plants. It is a 29 gallon tank with the critters I have in my signature. PH is 7.5, Ammonia and Nitrites 0, Nitrates between 10-20. I have a Finnex Fugeray Planted+ that stays on for 7 hours. I dose Seachem Flourish twice a week and I switch from dosing with Excel to not every couple months to see if that ever makes a difference (it does not seem to). I also have Seachem root tabs for the amazon sword. Everything I read online would say this is a great set up and everything should grow like weeds. I have had like 12 stalks of Water Westeria die, dwarf water lettuce and moss that doesn't die but also doesn't grow, and Amazon Sword and Anubis that are slowly (sometimes rapidly) dying. Could anyone look at the pictures and let me know what they think? I am just trying to grow nice anything for my fish. Thank you for your time. Oh and to add about a little over a month ago I switched my substrate from gravel to white sand you can't tell cause it keeps getting brown on top of the sand and doesn't seem to vacuum up well.
