Hi everyone!

I've got a 300 liter (75 g) tank with a low fishload but with lots of
plants, Amazones, Java fern, Riccia and many more. I'm adding preassured
CO2
with a reactor designed for a 400 liter tank. Allthough I'm not getting as
much CO2 into the water as I'd like to, most plants are pearling nicely.
pH
is on the high side with about 6.8 and gH is 5. I'm adding Tropica liquid
fert. dosed as recommended by Tropica and a few drops of iron. Lighting is
4
SunGlo 4.200K at 4 * 36 Watts. Photoperiod is about 12-14 hrs.

I have very little algea in the tank, but recently I've seen some of those
long, nasty disgusting aglea-strings that looks like a long human hair on
some of the plants. They can be removed by simply pulling them out, but it
seems useless to even try to get them all. Now to my question; Does anyone
know if this perticular type of algea is caused by phosfates (have no test
for that) or anything else inperticulat that I CAN adjust, such as
lighting
or fertilizer. Or is there a critter that'll eat the stuff?

You said you're not getting as much CO2 as you'd like to. At gH 5 and pH
6.8, you're possibly overdosing CO2. Remember the 3 are related. pH6.8 may


I believe that the KH, pH and [CO2] are the three related parameters. If your
KH
is 5, then, using Chuck Gadd's converter, your [CO2] is on the high but safe
side.

I'm just about done with my fishless cycle (NO2 finally down to 1 ppm!!) and
added
my plants about a week ago now. A couple of days ago I started getting lots of
the hair algae, too. All I've added are Fluorish Tabs in the substrate and
some
Fluorish liquid fertilizer, with a few drops of some RedSea Flora Fe. I too,
am
hoping that there is some critter that likes the stuff, and am hoping that the
hair
algae is just a new tank thing.
