Ah, Gregg Watson... Confusing the names here, and I was in a hurry... sorry 'bout that.
50l is about 13,2 US gallons, so that sounds about right. I figured that for 20l (5,3 gallons) I need about 0,4 teaspoon... I'll grab some exact tools from uni tomorrow.
So, I need the PMDD in addition... I'll look into ordering some. Problem is that the shipping is quite expensive to Norway, so I'd like to get as much as possible, maybe even ordering with someone from here.
Do I really need to add nitrate? I was expecting to get this from fish... I know I didn't say anything about fishload, but it will be moderate. I guess just having a fish would be "moderate" for this size of tank..
But of course, if I need to add extra I will.
More about the tank; as mentioned about 5 gallons (actual water), 38w CF light. I'm trying my hand on Java Moss, Riccia fluitans
, Hygrophila corymbosa
"Stricta", Hygrophila corymbosa
"Siamensis", Microsorum pteropus
"Undulata", Cryptocoryne wendtii
"Green" (all from Tropica). Right now the fish is four Zebra Danios, but the plan is to have 2-3 Dwarf Puffers (hence the asian plants). The substrate is sand 0,8-1,2mm, so iI guess I need some root tabs too. Any suggestions on brand and where to get?
Thanks for any help, and sorry for any stupid questions. My first planted tank, and all the info can be a bit confusing and overwhelming at first (and yes, I have read Rex's guide. Several times. I'll read it again soon
