I'm just setting up my first aquarium in years and have been scouring the net for info and generally have dug up what I needed, however now I'm beginging to encounter specific issues I would love to hear from you more experienced folks.
First things first my set up;
Tank - 50 gallon, 122cm L x 35cm W x45cm H
Filter - Eheim Pro 3 600 (probably overkill but its a long story I wont go into)
Light - One T8 48" aqua one sunlight bulb
Fish - 2 platies, 1 adult guppy 2 immature guppies
Plants - a handful of Java moss (that moss that looks like a vine)
Tank has been set up/cycling for 2 weeks
So my questions specifically are
1. Have a slight milkyness in the water (fairly faint but defintely there) and has been since day one. Initally thought is was the rock flour in the black sand but by now it should have settled down? Probably bacterial in that case but should it persist for this long in a new tank? (btw changing 10% of water every 2 days). Water is pH 7 and from our rainwater tank so no artifical chemicals etc in it. N levels - unknown, awaiting test kits to arrive (living in regional Australia has its down sides). Any thoughts on how to proceed? The milkyness is driving me nuts but doesnt seem to worry the fish.
2. Would like to add more plants over time but my gut feeling is my light is too low even for low light plants?
3. Stocking. I would like to keep maily neons/cardinal/rummynose tetras when everything has settled down and some guppies with a few small peaceful cat fish ( say a 50/50 split with the bioload on the guppy/tetras. tried the online stocking calculator and saw some big numbers (too me anyway) and just wanted to see what people with experience think.
Thanks in advance
