    and right now what is taught in biology classes is that there are 6 kingdoms of life- archae, eubacteria, animalia, plantae, protista, and fungi. Algae fall under the protista kingdom because they don't have REAL leaves (with cuticles, layers, etc), no REAL stems, no REAL (nutrient absorbing) roots, etc. and many are unicellular anyway. Not all algae are green plants either... red algae, brown algae, and diatoms aren't green.
    yes, plants did evolve from GREEN algae, (did I mention kelp is a brown alga?) but that's the point... they evolved.
    Just like protozoans aren't animals, or slime molds fungi, algae aren't plants.

    so... macro algae like kelp and caulerpa (sp? it's been a while) are protizoa?

    i thought there were like 10 kingdoms?

    no, Kelp is al alga. It's a brown alga too... so I was saying that since plants evolved from green alga, kelp (which looks probably the most like a plant out of any of the other algae) had a different evolutionary path and therefore shouldn't be classified as a plant.
    Protozoans are animal-like protists. (hence the zoans... and I just realized the "proto" (proto-before zoans-animals) is probably there because animals evolved from protozoans... all this time and I hadn't realized that? *bangs head on wall* it's so obvious!)
    anyway, protista is like a garbage kingdom. Everything that doesn't fit in the other kingdoms basically goes there :P there are animal-like protists (protozoans), fungus like protists (slime molds), and plant-like protists (algae). They're not really sure where to put them because they have characteristics of other things.. for example there's a green alga (that swims) called euglena that during the day photosynthesizes, and during the night it eats other protists. So it's both an autotroph and a heterotroph (plant? animal?). with slime molds, they have a really complex life cycle. they first start out as amoeba-like single cells, eating bacteria and stuff in the forest floor, and then when it rains or something suddenly all the single cells come together (chemical signals?) and they become this huge (relatively speaking) single thing. In some slime molds, the single cells actually fuse, while in others they just stick together. Then some of those become spores and that's how they reproduce sexualy. (I'm not exactly sure why they're FUNGUS-like protists... but what the heck)

    note: kingdom "monera" is now broken up into two- kingdom archae and kingdom eubacteria.

    It seems this topic has changed since it started, but here's my answer to the question. You do not have to boil tap water for aquatic utrics. I have grown several varieties, all in ponds or containers fed with tap water. I don't have super heavy water, but it is by no means the purest.

    The best thing you can do for an aquatic Utricularia is to put it in a pond environment with other plants; that way you get lots of daphnia feeding your plants, and natural organic matter creating a good pH or whatever - in any case it works much better than jars under lights inside.

    Well it's been outside for the past week and it seems to be doing alright. It's in distilled and rain water and it's doing ok. Thanks to everyone who posted.

    Ok I just can't resist any longer!

    I keep seeing this topic on the main page and think to myself. I like my Utrics boiled for about 30 seconds and then stirfried with a little garlic and ginger.

    I've grown quite a few aquatic species and can definitely state that algae is an inevitable problem. Best bet is to establish a balanced aquarium well before introduction of the Utricularia, say a good month. Worst bet is to use high light and transparent aquaria with no other species. Boiling, gamma radiation, and devout prayer will fail because the algae my friends is already on the Utricularia and is introduced with it. I have heard of tentatidve success using dilute hypochlorite (laundry bleach) to sterilize the Utricularia, but can't confirm this by my own experiments. I don't remember the recommended dilution, but do recall it was very dilute, and a quick dip.

    A "quick fix" method is to grow them in mineral free water contained in an OPAQUE container, keep it in 4-6 hr. broken sunlight with a layer or 2 of white plastic laid on the surface. Not too aesthetic, but the plants I grew like this throve and flowered. I have never had indoor success with these plants, ever, although in a well balanced aquaria it should be possible. Short term growing is possible, but the algae always overcame anything I ever tried eventually.

    I suggest U. macorhiza as a good beginner subject.
