Well i'm working upon my planted tank again and trying to get the plants back up to optimal health. I have 34gallons, 3 x 20watt T12 tubes and CO2 at 20ppm - its very bright now...even a little washed out.
anyway i dose KNO3 to keep 5-10ppm more towards 10ppm and 5 being the lowest i'll ever let it get and I dose Tropica Master Grow which is heavy in K (potassium?)
My tap water is very hard so i dont think i need to dose micro's but i have Flourish if you think i should.
My question is I think i read that you should dose ferts according to your iron reading i.e if no iron is there the rest wont be? Well I'm dosing the recommend dose of TMG split in half once a week, half on saturday and half on wednesday.
But when i test for iron i get nothing??????
I know my iron test kit works because i replaced the subsrate about 5months ago and i have a several algae break outs and my iron levels went through the roof!
so should i add iron seperately like i did last night, here is my proposal:
Check KNO3 and dose accordily
Check PO4 which is currently at .5ppm
check IRON and dose to keep at 1ppm?
dose TMG as per above
Or should i dose TMG at full strength whenever my iron reading is 0ppm
