    Why is this happening?

    I have cut back Eleocharis sp back to the substrate after initial planting the same as you. Give it a little time, and it will kick off. Then there will be no stopping it. You may experience a little algae around the stubble left behind. As an aside, when I add it to a tank with uber high CO2...

    Narrow leaf java fern - Latin name?

    Gfish, You are thinking of the "needle leaf", which is thinner than narrow, and widely used in Asia. Supercoley1 has some in a tank in his journal. Dave.

    Anubias and high light

    I have had Anubias sp growing close to the surface, and out of the water with no problems (lights were T8s). You should find it grows faster, and flowers like mad. Dave.

    Marsilea crenata question.

    Coolamundo, George. I always thought my original Marsilea sp was crenata (from Greenline), but the emerged growth I have with the Aquafleur is about 20cm, which made me a tad suspiscious. I`ll plant up what I have tomorrow during the footie. :thumbup: Dave.

    Marsilea crenata question.

    I have just bought some Aquafleur Marsilea crenata and it looks to me as if it going to be way too tall for my requirements. Does anyone know how tall it grows submerged? I am hoping for one or two cm at the most. I knew I shouldn`t have put my original Marsilea sp in my propagator. It all died...

    utricularia graminifolia

    I have grown it in play sand with EI dosing levels. My tap water was very soft. It is a strange plant in the sense that I have seen it in tanks that have done well in the IAPLC ,where it looks leggy to me, and nothing like the compact growth I was getting. One bit of advice I can give is don`t...

    Amazon deficiency?

    Don`t bother with the test kit. Iron is difficult enough to test for in lab conditions, let alone with a hobby test kit. Personally, I have never kept these types of plants before, so I can`t comment how significant targetting the dosing of iron is, but I would be surprised if it was deficient...

    Limnophilia sessiliflora melting

    Not when introducing them to a tank with good CO2. Whilst I haven`t used Crypts extensively, I have shifted a few from tank to propogator and back to tank without any melting. Gently ease your CO2 up over the next day or two and push the dropper closer to yellow. Keep an eye on your fish, and...

    crypt propagation

    All my Crypts are growing, although nothing like TGM. My plants were taken out of my 240l when I stripped it down, and put straight in to the propagator. One or two leaves died off but, on the whole, the plants took to it like a fish out of water. The C undulata seems to be doing best out of the...

    crypt propagation

    Chris, I grow Cryptocoryne undulata, parva and petchii (i think) using this method: viewtopic.php?f=56&t=6215 They are all thriving. I don`t think tropica do my variant of undulata any more, just the broad leaf version. Dave.

    Sluggesh growth after rescape

    I have set up two tanks with Eleocharis parvula. The first one from a while ago took a couple of months for it to start growing, then it exploded in to life. The current one, which I have recently started has the Eleocharis parvula growing really well from the outset. Both tanks are/were EI...

    Acicularis 1st trim

    I generally try to avoid cutting new shoots, but there will be plenty within the main plant mass that will get cut. It isn`t too critical in my experience, though. Cutting back Eleocharis sp sure does get messy. Dave.

    Rotala rotundifolia planting advice

    I generally allow stems a good growth period before I cut and replant them. Just replant the cut off stems in the substrate and they will quickly root. The original planted half should develop two new growth points, making the plants look bushier. Any decent pair of sharp scissors will do the...

    Some "alien" invaders - Do you know where to find some?

    It looks a lot like Hemianthus micranthemoides to me. Considering how much I like and use HM, I`ll have to keep an eye out for this plant on my wanderings. Dave.

    what's the downside to using e. parvula as carpet plant?

    Sam, it should stay well anchored by its root structure. Like any plant that sends out runners, you have to keep on top of it with scissors. I am just about to use E parvula for the second time. Dave.

    echolaris parvula ? invasive how to control

    The HC tends to break out over the top of the E. parvula. A narrow depth of field put the HC out of focus in the pic below, but it shows the HC climbing out over the top of the grass. The two aren`t directly compatible in my experience, but they look nice side by side, each given their own...

    Staurogyne sp planting

    The only thing I would say is that with stem type plants, I tend not to trim them until they are established and showing immersed growth. Give the plant time and it should turn around. It isn`t too difficult to grow. Dave.

    HC going brown

    Drop checkers aren`t particularly accurate, that it is true. It is still down to interpreting a colour and using a hobby grade pH indicator, but they are useful as a general guide, albeit with a very slow reaction time. They are, however, better than pH controllers because they are only affected...

    HC going brown

    If there are no fish in the tank yet, then why not just whack the CO2 right up and maximize plant growth and health? No offence, but pussy footing around with the pH controller for a .2 change won`t give you a quick turn around in plant health. The controller is measuring the pH of the water as...

    Re: What plants will survive best in my tank Judging by the specs of your tank, I would say you could virtually any plant you wish. For a bushy, stem planted back ground, Rotala sp Green is hard to beat in terms of looks, and ease of growing. You could also consider Micranthemum umbrosum or...

    Rotola, how do yo get it vertical

    I`m not sure what type it is in that tank, Marsilea all seem to look the same to me. Marsilea has a Glossoesque look to it, but grows more sparsely and is easier to control. I think it is under rated and under used, although Amano has used it quite a lot. I think mine is M crenata. I have just...

    Cyperus helferi

    What are your CO2 levels, and how are you measuring them? I suspect your dosing to be on the lean side. Try mixing your own ferts using potassium nitrate, potassium phosphate and trace mix from one of our sponsors. Take a look at the EI method of dosing and modify this to suit your situation...

    green rotal rotundifolia

    I used to get seriously red Rotala in my Juwel Lido, but always thought that it was because it was Greenline Rotala as opposed to Tropica, which I have never turned red under my Arcadia T8 lamps, which are their freshwater tubes. The Lido is in storage at the moment, but when I get the chance...

    Crypt's plants

    All my Crypts have been emersed growth from TGM, but I have never had any melting. I suspect it is down to the CO2 levels in the water being good enough to prevent this. Dave.

    c.balansae help

    Provided the water column is well dosed, I would look at CO2. Some people do experience crypt melt for a while when the plants are newly introduced, but even this can be avoided with good CO2; good being at non limiting levels distributed throughout the tank. Dave.

    Utricularia graminifolia

    DO NOT put shrimp in to the tank until it has become established. They used to shred mine blade by blade, leaving a horrible floating mess. My UG was always grown in an inert substarte. To plant it, you will need to cut the rockwool in to small cubes for planting. Dave.

    Moss I.D needed

    It could well be Leptodictyum riparium "stringy moss". I had some in my 120cm. It does look stringy, and grows upwards. Mine lasted two or three weeks before I got rid of it. It wasn`t to my taste. Just attach it to the wood, or whatever you want. It is fairly fast growing, without any special...

    Eleocharis Vivipara - propogation

    Cheers, Ed. I guess you mean that you can snip it off from a point where the stem bifurcates/splits in to more than one.

    tips on growing hc

    I find with HC you need to give it the best possible start. For me, it sits around for a good while, doing nothing, then it takes off like a weed. Usually when you first buy it, it will be in its emmersed form. It tends not to like the double experience of being immersed and planted out at the...

    Hygrophila corymbosa `Siamensis` 53B.

    I have had a lot of flow issues with this tank, which have only recently been addressed properly. Perhaps it could be from not getting CO2 in to that corner, which is only manifesting itself now. Ah well, lets hope it picks up and I can break my scaping virginity in time for competition...

    Which stem plant?

    I think you will find most stem plants to be fast growing. For a nice bushy effect Rotala sp "green" is ideal, but for a red colour try Rotala rotundifolia or Nesaea pedicellata. Ludwigia arcuata can give a more orangy colour. More delicate looking stems include Micranthemum umbrosum and...

    Is there such a thing as a 'highlight' plant? An experiment

    I would be interested to see how HC copes. I suspect it would reach for the light, rather than cling to the substrate. I doubt whether Zig`s scape would have worked under too low a light level. Still, I can`t say too much unless I try it myself. Dave.

    I have just started growing Staurogyne myself, and pretty much agree with George (I doubt if there are many that know Staurogyne better than George). The grassy foreground will either be Eleocharis acicularis or E. parvula. It has been very neatly mown. Dave.
  84. Dave Spencer

    Nesaea pedicellata

    I found it very easy to grow, but that is using EI alongside ADA Amazonia. I can`t see it being too difficult as most stems are essentially weeds, and grow like them. Personally, I won`t be using it again, as it lacks the finesse of other stems such as HM, MU or the Rotalas. The stem is too...

    Riccia Carpet?

    The tank I showed has 80% substrate coverage with rocks. Riccia looks so much better as a feature plant, rather than an after thought on the odd piece of slate. I used my lights on a split timer, so in the evening only the rear light was on. This would show the pearling off in all its glory...

    Pruning advice - Eleocharis acicularis?

    When you first plant it, you should be brutal and cut it right back. The growth will be emersed, and go brown and die. This stage becomes an algae magnet. If I were you, I would cut it right back now and wait for the healthy submersed growth. Dave.
