I'm new to planted tanks and am running a very low tech set up, but will eventually go mid tech and perhaps start running some CO2.
Tank has been running for 7 months: 130L (34.5 Gallon) 90x37x42cm (42cm high)
At the moment I have:
1x Amazon Sword (in tank for 2 weeks)
3x Java Fern (2 weeks - split from 1 plant)
3x Hygrophila corymbosa (I now know these aren't true aquatic plants - been in tank 6-7 months)
1x Banana Plant/Lily (2 weeks)
1x Anubia nana (7 months)
I've taken some photos to see if anyone can identify any nutrient deficiencies. I can perhaps see Magnesium and Potassium defiencies? One of the sword leaves is curving downwards on the tips and edges.
I dose Seachem Comprehensive once a week (about 1/2 to 1 capful) and the sword and Lily have Seachem Root Tabs right next to their roots. These will be replaced every 2-3 months. I also put a couple of teaspoons of calcium powder in the tank every 1-2 weeks to help my Mystery Snail. Use Prime as the water conditioner and sometimes dose excel when I remember.
No CO2 (maybe in the future as I add more plants)
Running the stock LED light that came with the tank (2 strips of white LEDs) however about to buy the Fluval Fresh & Planted 2.0 to future proof myself and will only run it at about 40-50% for the time being. Lights runs for 6 hours daily and about 40cm above top of small gravel substrate.
pH - 7.5
Ammonia - 0
Nitrite - 0
Nitrate - hovers around 20ppm
gH - 6-8dgH (colour change used to be more obvious, now it seems very subtle)
kH - 4dkH
Attached image of water parameters in the town water.
Temp is 25-29C (it gets hot in Australia!)
7x Sterbai Corydoras
8x Pristella Tetras
7x Cherry Barbs (will be getting 1-2 more)
1x Mystery Snail
At least 50% water change each week, sometimes split up into 2 30% water changes. You can see the brown algae (diatoms) has stained the leaves of the Hygrophila, I'm unable to remove the stains. Hopefully the diatoms will die town as the tank matures. Run two HOBs with 1200L/hr output and a sponge filter with a bit of carbon in the hollow centre (not enough to make any real difference).
Is there anything else I should be dosing based on the look of my plants? Some will be acclimatising to the new tank given they've only been in there for 2 weeks. There's definitely some deficiencies there, maybe magnesium and Potassium being the main two.
Should I dose with Seachem Equilibrium or any macros?
