On the other hand, maybe the answer is not less light, but more nutrients. >Combined with the fact that your tanks are densely planted, your crypts are >facing a tough battle for not only carbon dioxide (which they need more than >other plants do) Where did you hear this. I've thought this too, but have never seen it stated anywhere. >Let me know if all this makes sense to you. Well, it makes a hell of a lot more sense than the guy who told me plants release hormones which stunt the growth of laceplants. I think perhaps I'll try keeping my cryps by themselves and see what happens. Take out the *ahem* water sprite ans aponogetons that are so good at controlling algae because they suck the nutrients out of the water so quickly.
