Great! So I'm NOT crazy! Now why exactly does this occur? I don't like
mysteries! The only explanation that makes sense is 12-18mts is the length
of time it takes an "almost optimum" aquarium to build up serious
alleopathic compounds that will inhibit plant's growth. What do you think?
You know, I've never noticed the heating cable dicussions before thinking
I'll never need 'em in a big way. The tank I DO have cables on i
experienced no slow-down.
BTW, what's your opinion on those "hot water" substrate heaters...do they
work at all ? How does their performance compare to traditional electric
wire heating cables?
