What is this?
Ok so yesterday there was not nearly this much of whatever this is in my tank.
I'm at my wits end with this crap, my water parameters are great, I have high light ~200 watts t5ho 6700k on my 40g breeder but lots of plants and daily ferts plus do 75% WC each week.

How can i get rid of it :banghead::banghead:

I'm about to start cutting off all the leaves with it on it

Looks like some type of hair algae to me. You have super high light with no co2. I recommend cutting your lights down by at least half to about 100 watts.

I'm doing diy Co2 have been since the start.going pressurized soon

Epic Algae you've got there. I see hair algae, staghorn algae, brush algae, blanketing GSA. Honestly, that's probably one of the worst infestations I've seen.

DIY CO2 starts to loose effectiveness beyond about 30g, and a 40B is about 45g. Not to mention that you have, what 4-5 T5HO bulbs above the tank? That's ridiculously high light. I've seen tanks where two T5HO bulbs caused algae issues without CO2. I'm not sure what you were expecting to happen with all that light, but this is what I would have expected.

Long story short, dramatically reduce the light and go pressurized CO2 ASAP.

What can I do to get rid of it while I reduce lighting? I have a 36" quad 156 total wattage fixture and a 20" 40 watt dual fixture.

So exactly how many watts should I use for dwarf hair, baby tears, crips, swords, ferns.

cyris69 09-01-2012 07:36 PM

Ok I cut out all but 80 Watts

Bringing it down to two bulbs (2x39 I assume?) would have been my recommendation. If you have excel, you might try dosing that for a few days assuming you don't have anything Excel sensitive (Moss balls, vals, some stems). That should help with the algae. H2O2 is another viable option. Once you get your pressurized CO2 running (as per your other thread) you should be golden, although I would look at dry ferts as well.

Ok, excel or Tetra Algae Control at PETCO

Other forums show the tetra stuff works wonders and is much cheaper until I get my co2 situation all set.
"Broad spectrum algae controls green water as well as blue-green algae, brown algae, hair algae or blanketweed"

I would never recommend a designated algae control chemical. They are generally not very plant or fauna safe.

Yup. Chemicals for killing stuff is the last thing to want to put in a fish tank. Algae eaters like amano shrimp could probably clean it up. I also hear that rooibos tea might be worth looking into. But just make sure your dealing with the source of the problem too.
