Some new plants melting in new ada aquasoil setup
I changed from regular aquarium gravel, which leached high amounts of calcium, to ADA amazonia 2.5 weeks ago. I currently have some issues with my Glossostigma elatinoides, staurogyne repens and ludwegia mini super red which all seem to be melting away. I have these plants about 2 weeks now with all other plants from my old tank doing good, besides some green spot algae on leaves and driftwood, which however is improving and i think it was due to the high ammonia. I currently have no fish yet in the tank except some baby fish which to my surprise must have been eggs on some of the plants from my previous set up, and even survived the 4ppm ammonia throughout the last few weeks. They are doing great and growing, but too small to add my other fish.
I have pressurised co2, ph controled, with my ph being about 6.8 with no co2 and 6.05 at all other times, day and night.
My tank is 290 litres with surface skimmer, external cannister filter, powerhead above the co2 diffuser, 2 × 120cm led lights, one 45 one 49 watts, dont know the other specs, one came with tank the other is designed for plant growth, aquaone plantgrow. Substrate ADA amazonia
My water parameters:
Gh= 8, normally 4-5 but added seachem equilibrium
Kh = 3
Nitrate = 20-40, strong orange colour but not red
Phosphate= 0.5-1.0, kind of confusing as my previous setup always had 5ppm using the same fert, maybe absorbed by the ADA amazonia ?
Ferts are LCA all in one dry fertilizer mixed in bottled water.
Dosing 3× a week 30ml with 12ml in 100 litres of water resulting in 0.5ppm iron, 7.5 nitrate, 1.3 phosphate, potassium, 5.27 and small amounts of mag, zinc, copper, manganese, boron and molybdenum.
Please see photos attached.
Since changing the substrate, I know it hasn't been long, no more curled leaves on stem plants due to high calcium all other plants doing good.
What could be the reason for these new plants melting? Should I give them more time? Not sure if they were grown emersed or not. Also will the algae on the driftwood disapear eventually? The GSA on the Amazon sword is becoming less but my annubis are suffering and coated.
Any help appreciated!
