I WILL POST SOME PCTURE LATER
THANKS

You have 5 wpg? Did I read that correctly? If so, I would go for about 1-2 wpg at most..

That is WAY too much light. While crypts can take more light than folks think, I think this is too much. Try shading it a bit more...........

I use 450w of mh for my 180. Crypts are okay under the light, but grow TALLER when shaded a bit.........

Also, please advise on your EI dosing amounts/schedule......

my dosing kno3 10ppm x3wk, po4 kept at 2ppm, iron 3 xwk, GH BOOSTER with water chang 5gm , GH 4-5.?
yes, i do have 2 x55 CF + 2 X20 WT AQUA GLOW.
LIGHT TIME 10H
here is an old pic of my tank befor trimming, i will post a newer one soon
