The tank it's 20" high (standard 25 gallon). Take about 4" away for the substrate (Eco-Complete). I'll be dosing EI, just as I'm doing in my 55 gallon.What are the dimensions of the tank? What type of substrate will you be using? Will you be dosing? What kind of inhabitants do you plan on having?
The first question is related to the lighting while the others will directly determine whether HC will work for you.
In regards to HC, it'll work, it's been shown on numerous tanks that you can grow HC with Excel given other conditions are appropriate.
It's 2x24W. It does not sound like much, but it looks quite bright over a small tank.How much lighting is your unit?
I had a pressurized system before, and dosing Excel is a lot easier. I might go back to a CO2 system one day, just not ready yet.Since then I've gone the route of pressurized co2 and dosing with the EI method.
Best of luck to you and your HC though, quite an awesome looking plant when it fills in
