Couple good replies above.
A few main things to consider that must be addressed:
What kind of lighting are you using? (Wattage, degree K, time on, type)
Although the LFS may say that your pH is fine, what is it?
Do you run any kind of CO2 supplementation?
Is your water return from a filter aggitating the surface water? (will
reduce your CO2 concentration)
Are you running an airstone of anykind anywhere? (this will kill your CO2
concentration)
How many fish do you have in the tank and what kinds? (any plant eaters?)
What kind of plants are they? (as mentioned in another reply, Crypos
normally die off with rapid water changes)
I converted to live plants about 8 years ago, just to try it out. I don't
have any supplemental CO2 running but I also use canister filtration and no
airstones what-so-ever. My lighting consists of two regular fluorescent
lamps per tank (20 and 40) with one bulb rated around 6000K and the other
pushing 12000K or actinic. My tanks aren't what you may consider heavily
planted, but if I leave them alone, I'll have one hell of a trim job in the
making. I have Crypos in the 20 with a new addition of corckscrew val (I
like it and want more of it) and in the 100 I have one uncontrolable amazon
sword plant that I can't trim fast enough. My fish loads are very
conservative: 1 angel in each, 3 Pricilla Tetras, 1 clown loach, 1 khuili
loach for the 20 and 1 red tailed shark, 1 irridecent shark, 3 khuili
loaches, 5 ottos in the 100. I also have a plethora of Malasian trumpet
snails (MTS) that control plant die off waste and algae.
Mainly, watch the lighting conditions and water aggitation. A lot of basic
plants are rather hearty when considering the other water conditions. Your
fish will usually tell you something else is wrong regarding ammonia and
nitrite before your plants do.
