My tank is heavily planted with vals. I have both corkscrew vals (Vallisneria Americana) and contortion vals (Vallisneria Asiatica). I have recently cut my lights in half to 1.73 wpg cf
and am running pressurized co2
. I dose 1/2 the amounts of the EI and my vals are growing uncontrollably. I'd hate to see how much I would have to trim at double the light. They will do well for you in the "low light" as well as anything, although it is unnecessary IMO
. Also, everyone says that vals will melt with excel. Last week I used the initial dosing once a day the entire week to eliminate some BBA I was getting. Not a single val melted. Just ease them into it and they are fine.
