Please help diagnose plant problem..
I've started my 29 gallon planted tank a couple months ago. Crypts and
Anubias seems to be doing fine. I have two Aponogeton crispus that is showing brown spots on the older leaves and finally turning into holes. New leaves will come out nice and green but will start turning brown after a week or so. A picture can be found at: http://www31.brinkster.com/poeshomepage/apons.jpg Does anyone have an idea what the possible cause/cure for this is? My tank info: - 29 Gal - 1x65 Watt CF with AHS brightkit on 12 hours/day - Substrate is Fluorite/gravel mix - Temp: 84 F, pH 7.2, Nitrate 20-25 ppm, Iron ~ 0.1 ppm, no info on phosphate or other parameters (I don't have other test kits) - I dose PMDD (only the chelate trace mix) weekly to maintain Fe level at ~ 0.1 ppm and have been doing ~ 10% water changes every other day to keep my nitrate down. I'm also struggling with spot algae outbreak which seemed to pop up whenever I add too much trace elements. I'm not certain about this tho. Any help would be greatly appreciated! thanks so much!

The only thing in your PMDD is the trace mix?
You're not dosing Potassium at all? You should invest in a water hardness kit to determine GH and KH... They're very cheap. You may need to dose Mg and Ca as well. Isaac "PR" wrote in message om... - I dose PMDD (only the chelate trace mix) weekly to maintain Fe level at ~ 0.1 ppm Poe |

I followed the PMDD recipe from thekrib.com. It includes K2SO4 and
MgSO4 in addition to the chelate trace elements. I also should add that my fish load is quite high: 2 Neon blue discus 2 Clown loaches 3 cardinal tetra 3 Siamese algae eaters 1 bristlenose pleco 1 Blue ram. "Isaac" wrote in message gy.com...
