In my 450L tank i have some issues with my staurogyne repens,the leaves on some plants are turning a greyish colour and then going mushy and disintergrating.I had this before and upped the co2 and increased the flow in the tank changed the tank scape and planting a bit as well to get good flow and get all the plants in the tank moving in the flow.I replanted some more staurogyne from my nano tank where strangely they thrive in a spot where lots of co2 bubbles pass through.After about 4 weeks good growth and pearling the above problems are returning.
co2 on 3 hours before lights on DC green off 1.5 hours before lights off DC very light green/almost yellow.
Flow is 8x tank volume (maybe need more but the plants are moving well and ones on the back get battered a bit.
EI dosing 3x macro 3x trace a week.
Macro mix 1teaspoon Potassium Phosphate,4 teaspoons Potassium Nitrate,6teaspoons Magnesium Sulphate in 500ml of water dosing 90ml 3x a week.
Lighting 4 x 36watt 7 hours a day all 4 are on together for a total of 6 hours a day remaining one hour is lit by 2 tubes.
Tank temp is 25 degress C
All the other plants HC,Eleocharis,Ludwiga repens,Rotala,etc are doing well
Substrate in tank is JBL Manando
I was going to add some Easy Carbo and maybe some root tabs to see if this made any differance.In my nano tanks i do not have any problem with this plant with what i see as strange.
Hope someone could give me some advice on what the problem is and what to try and do to sort it out.
