Hi Guys - go easy on me this is my 1st post !!
I have a Juwel Vision 180L (40G) tank set up for discus.
The pH is 6.5 by use of a pH6.5 Buffer and I use a Softening pillow to decrease the kH and gH (1 is 13 and the other is 6 - can't remember which).
The hood has space for 2 30 inch bulbs. I have 1 25W Arcadia Original bulb and 1 25W Arcadia Freshwater bulb, and both bulbs have reflectors. Now I don't know how effective these reflectors are, but I'm guessing that gives me about 2WPG - the photoperiod is 12 hrs.
The substrate is sand.
The fish are - 4 discus all under 4 inches
3 Clown loaches
The plants are:
2 big java fern on bogwood - so quite high in the tank
Lots of H.Polysperma - green and red variety
10 Tough leaf Swords - I only paid for 2 but the guy sent me 10 so I kept them all.
Some cheap goldfish weed - not elodea (the one more common in UK)
2 Anubias (Unknown type)
Sorry all that is so vague - but I'm just beginning with plants :roll:
As fertilizer I use LeafZone, root tabs and Pro-Aqua Fertilizer bags (from http://www.aquaticplants.eu.com/Pro%20aqua%20Plant.htm
Now the growth of the polysperma is fantastic although the leaves all have bits of 1-2mm long strands of (hair?) algae on them. The Java ferns have more of the same, the anubias have blacker hair algae on the edges of the leaves, the swords have some hair on them, and the new leaves that grow uncurl to reveal holes and ragged edges so I have to just cut them straight off. The tank is snail free as far as I know and there are 3 clown loaches that would soon eat any stray snail.
I read that by adding CO2, the plants will out compete the algae, but then I have to add special fertilizers in specific amounts. Do you think CO2 would help ? Am I over fertilizing ? Is there too much light for the Java ferns higher in the tank, and too little light for the swords on the floor ??
Lots of questions I'm afraid !!!
