    Jerry, tank looks wonderful! I'm currently trying to balance plant and discus to find that sweet spot. What kind of substrate are you using? Are you using anything to help the plants? Your Discus also look great! What kind of food are you feeding and how often? Sorry for all the questions.

    Thank you James, I don't use pH controller and I'm injecting CO2 non-stop - but with quite high water-surface movement, so it makes very stable CO2 level as well as pH. Lights are T5 HO tubes, 4x49W. I'm switching tubes on and off gradually - but I'd like to have option for better intensity regulation, so I'll probably switch to LED chips.

    I was lowering Gh quite slowly, around 2 degrees per week. Discus were happy all the time, plants didn't melt at all - even cryptocorynes are fine.

    no problem at all, substrate is river sand (1-4mm). I'm not using any special substrate, but I'm using JECOD DP-2 dosing pump for fertilisers to keep stable levels of NO3=15mg/l, PO4=1.4, K=10, Fe=0,1-0,2mg/l. I'm measurng water parameters every 2 weeks and then I adjust dosing formula if necessary - it's very close to PPS Pro method, but I'm trying to keep very stable conditions.
    Food - I'm switching quite a lot of kinds - Discus special (it's BH + vitamins etc.) 1-2x per week, frozen worms (black and white), artemia - its one of their favorite. Granules - Hikari Tropical Discus Bio Gold, Tetra Diskus, Tetra Diskus Energy, Sera discus color Blue, Spirulina & Chlorella flakes, fresh bananas

    Some new photo and video, both plants and fish are growing well. Plants still need a couple of months to get to the right size. I also have a new project, 1344l (355 gallon), 10,5 ft. long. Still in planning stage, but I already have permission from my wife (most important thing! :-)) and I've finalized stand design - it will be in the living rooms, so it needs to fit well in there I'm not planning this kind of planted tank, but some Amazon Swords and maybe Vallisnerias will be there. I'll setup new topic once I'll start with some real work on this tank
