The lillies have been difficult and dissapointing. Had 4 bulbs/roots, only 2 surviving still. neither thriving. Really surprised me because the ones I grow in my pond are so easy.
, yes, (had major probs with it at first, hopefully resolved now).
flourite substrate, though I'm now told that Schultz ( I think, still half asleep here) makes an aquasoil product for pond plants thats cheaper and better than flourite. Hearsay only, never tried it myself.
jobe's palm tree ferilizer sticks mixed in with substrate when tank was set up.
no liquid fertilizer yet, sooooooo many on the market, hard to decide which one to use, or go with home made.
