    Dear Gurus, this is my set up and currently entering its 3rd week of DSM. Picture taken was just after sealing up after 20 minutes of airing, hence you don't see any mist.

    My questions are:

    1. Based on the picture, are the hairgrass stocks growing well? I can see some tiny "runners?" shooting out from the aqua soil but are they what I think they are?

    2. Picture taken was a few days back. Now, there are some parts of the grass turning pale. Some at the tip and a couple of the strands has paled out totally. I've read up about melt down in new setups but will they recover?

    3. What can I do to help them? I'm thinking of getting fert and mixed it with water and apply in spray bottle every other day. Is it advisable to do that?

    2. Java moss on the drift wood seems to be dying. Can they survive the DSM stage or should I add them after flooding the tank? As you can see from the picture. Those moss planted into the sand are doing fine, but not those on the driftwood.

    I'm currently using ADA mini M and Aquasky LED. I believe lighting isn't a problem.

    I am a keen learner newbie in this hobby. Have some patient with me

    Thanks in Advance.

    Re: Hairgrass_DSM

    Nice setup.. but i dont understand why would you want to do a DSM with hairgrass and java moss..with HC i understand because it doesnt root well and is a tough plant to grow..

    I am sure with the current setup flooded from day1 and pressurised CO2, you would have had almost a carpet..

    This is the growth I had in 3.5 weeks starting from a few strands of dwarfhairgrass, co2 at 1/3 bps:

    Hi, thanks for the reply. Becoz I still considering getting a co2 system, space constrain. Currently I have flourish excel. However I'm thinking of letting hairgrass grow in before flooding the tank.

    Re: Hairgrass_DSM

    I have the same considerations on co2 too..have a similar set up but it's hair grass and monte..you are very patient..my setup was into its 2nd week before I see some mould strands growing. .that's when I quickly flood it..my HG is also growing damm slow (if any)..

    My experience is after flooding..They melt some more..and Roger (fishy business) said that plants need to adapt from emerged to submerged again..so additional melting should be expected..

    So from a non co2 point of view..I will grow it submerged the next time since melting is gonna happen anyway..and I can save time cycling the tank while the plants take root..just gotta push the plants deeper in..but not to worry cuz the new growth of HG will still peek out of the soil after they are growing..

    My 1cent worth. .lol

    Just curious, can you take a close-up photo of the hairgrass? From the photo, the leaf blades seem wider than normal hairgrass, might be another plant species.

    Hi UA, finally at home. Here are the closer look of my hairgrass.

    Do they look different?

    Okay, that looks like normal hairgrass.

    Re: Hairgrass_DSM

    Hijack my own post for a little bit.

    I have a nano tank which I started almost a month ago. Ammonia is present but not nitrite or nitrate. Which also means bacterial hasn't start to colonize yet.

    How long do they normally need to start colonizing a tank? I have fishes in there which I feed minimally once a day.

    Re: Hairgrass_DSM

    The beneficial bacteria colonies are probably still growing, but no yet enough to process and convert the existing bio-load, so the ammonia is still showing up.

    It usually takes around 6-8 weeks for a tank to achieve a stable cycle, but it can be longer or shorter depending on factors like the amount of ammonia to process, efficiency of the filtration system, the amount of bio-media for the bacteria to colonize, amount of plants, pH, temperature etc.

    Most of the time, its just a matter of waiting.

    Re: Hairgrass_DSM

    Hi people, I've flooded my tank more than a week ago and recently add on a cheap replacement cartridge Co2. I guess its better than nothing.
    Everything seems fine, with the hair grasses melting away and read they will soon recover. Finger crossed.

    Then today, I bought some riccia moss and threw it into a quarantine holder that sucker on the glass in the flooded tank. I went for a smoke and came back seeing a really snail, the most 5mm in length, crawling up the quarantine holder. Should I get rid of it or its totally harmless to the plants in the tank?

    I know its really a noobie question, but I do not want to harm any small animals in the process of my new found hobby.

    Thanks in Advance

    That probably a common pond snail... they are relatively harmless, but if you can see one, then there are most likely more that have hitchhiked over in the plants. If conditions are good and there is ample food supply they may multiply quickly and start to become unsightly, so if you don't want that issue later on, just remove as many of the snails that you manage to spot.

    How is riccia moss as carpet?If use wire mesh, will they be able to cover the metal parts?

    Yes, they will grow and cover the metal mesh... but you do need to trim the riccia constantly as it doesn't root to anything, if left to grow longer the new growth will tend to shade the bottom layers which will eventually rot and detach, then you'll end up with floating riccia carpets.

    Re: Hairgrass_DSM

    Hi bros, I did a ammonia test last Sunday on my nano tank and result was zero! Nitrite test was zero too! Happy as hell, I did the final test on nitrate and it's zero too!! Is it even possible?? What happened?

    Its possible for nitrate to read zero in planted tanks (actually there is still some nitrate levels, maybe just a few ppm, low enough not to show up with noticeable color change in the test kit). That usually indicates that the plants are using up enough of the nitrates to keep it low.

    Btw, do make sure you follow the test kit instructions and mix/shake the test tubes throughly and let it stand for a few minutes before taking the measurements. How well the solution is mixed can affect the readings too.

    I see. Didn't know that plants use nitrates as well. I'll test it properly the next time. Just did some trimming and water changr

    Yeah, one of the main nutrients plants consume is nitrates, along with many other macro and micro nutrients... even ammonium too.
