That is a big tank - about 130 gallons. Without knowing anything about the LED tubes you use, you may have high light. With high light you need lots of healthy, growing plants to keep algae from becoming a big problem. And, that means you need to have adequate CO2 in the tank. It is much harder to get enough CO2 in that big a tank than in a 50 gallon tank. Have you measured how much your water's pH drops as a result of the CO2? (Measure the pH after the CO2 has been off for 16 hours or so. Turn on the CO2. After a couple of hours measure the pH again. If the pH drops by 1.0 you probably have about 30 ppm of CO2 in the water. For other pH drops you can calculate your approximate CO2 concentration using this equation: ppm CO2 = 3 times 10 raised to the pH difference power. For example, if the pH drop is 0.5, 10 to the 0.5 power is 3.16, so you have about 10 ppm of CO2.)

How do you diffuse your CO2 into the water?

Plants need more than iron to grow well. They need nitrogen, potassium, and phosphorus - the macro nutrients. And, they need much smaller amounts of iron, and a big list of other elements - the micro nutrients. See https://barrreport.com/threads/ei-light-for-those-less-techy-folks.2794/ for information.

thank you for replying to answer 2 of your questions i use a sera CO2 reactor i have my CO2 on for 24x7 to keep PH under 7 for my discus if i have high light can i turn one of the 4 tubes off and go with 3.im going to stop dosing iron daily and switch to sachem flourish

cheers
