Hi
This will be my second journal (maybe for contest or maybe not

...i just want show people my works)
One word from the begining: in this tank layout wasn't important, this is small experiment with eleocharis and ferts routine with medium/low light and CO2. If I know that hair grass will grow so good layout will be different (not so symmetrical) but ...no one is perfect

.
Tank is custome made 64x30x25cm (about 12.7gal), light is one Philips bulb 18/965 + arcadia reflector. Like you see this is only 0.37W/l (1.4WPG) but for this layout in 10" high tank is enough. I study few Oliver Knott tank with low light and i must say that rule 2WPG is good in 15-20" high tanks but in lower tanks you don't must follow that. I think even HC or glosso will grow in that tank (of course much slower and not so good but good enough).
Ok. Lets get start...
Substrat:
I used few different "gravels" and substrat adds. In backgroud i used MHK Aquagrunt (plant substrat reach in Fe), MHK Floran (kind of lava) and regular gravel (3-4mm). I used activated carbon and dry bacteria (Tetra bactozym) on bottom. Gravel is only in background because in that part will grow eleocharis. In foreground i used only sand (1.5-2mm) because in that part will be moss on stones. I used PCV fillet to separate gravel and sand (i removed it at the end)
I put in some rocks but i dont know what this is (some kind of slate). Java moss is on small river slate (look almost like ADA ricca stones

).
I fill tank RO water with PGP Hydro-mineral, setup CO2 (presurred with Resun glass dispenser) and put activated carbon in filter (Aquaclear 150). I don't add any ferts (except basic K,Ca-X,Mg,Na,S in PGP Hydro-mineral)
At start water parameters was:
KH 3
GH 5
pH 6.7-6.9
NO3 0
NO2 0
PO4 0
temperature: 23-24*C
After first week i removed carbon from filter, change 10l water (100% RO + PGP HM) and add 0.3ml TMG. I also put in 10 cherry shrimp and 2otos.
There wasn't lot algae, only few short hair algae on stones.
Ok. That's all for now. More coming soon...
