ferts help needed

i have a 55gal tank with pressured co2 and 3 watts/gal of PC light..
I keep CO2 levels from 30 to 40 ppm...

I have been Dosing KN03, KH2P04 to 10ppm and 1.5ppm and flourish @WC days..

i have a green spot algae problem..
After reading WfxXx sticky post and Reg's web site i realized that i have not been dosing Potassium Sulfate.. that might be the cause of GSA (I think)

so i am going to order ferts from Greg..

my question is apart from K2S04 what should get for trace, CSM+B Plantex or Plantex CSM+B Plus Extra Iron...
(Flourish is getting exp)

Also please let me know if i need to order anything else... from greg....

Please take a look as my new dosing as well.. (TY MR. WfxXx)

50%H20 change
+/-1/2Tsp KN03 3x a week
+/-1/8Tsp KH2P04 3x a week
+/-1/8Tsp K2S04 3x a week
+/-1???? Trace 3x a week (Dont know how much to add)

Any feed back is appreciated..
Thanks


OOOHH - what a god send this website is..

don't bother buying K2SO4. If you up your KNO3 dosage by 1/4t 3x per week (so you will be dosing 3/4t 3x per week), then you already have plenty of K from that. With how high your light and co2 is, you need to be dosing NO3 higher anyway.

Buy the CSM+B with extra Iron. If you dose liquid, then make a solution of 2T in 500ml water, and dose 14ml 3x per week. on off days from the Macros.

edit>> apart from that, your dosing regime looks good. and unless you have low GH, you don't need anything else from Greg. Even then, you can get Ca and Mg products locally.

edit 2>> GSA is caused by low PO4 and low co2. K was not the issue.

GH of above 5d (90ppm) should be fine. It never hurts to dose a little Epsom Salt (MgSO4) along with each water change either just in case. 1/2t will be plenty.

It is 1/16t CSM per 20g's if dosing dry. So you could go as high as 3/16t 3x per week no problem. Just use a 1/4t measuring spoon and don't quite fill it to the rim. More wont hurt anyway if you just want to do 1/4t full.
