Unhealthy Hairgrass

[alechim]

Stash one away somewhere

Or is there too many people about that would not approve? Surely your able to take a pic of your tank, surely?

really really cannot, my work place is a no camera zone

[Verminator]

That seems a bit daft, almost unfair. You work for the military or something. Or not to hit to much of a political note for the far east, but against government laws?

I know how some of the Asian governing bodies over in various places can have ridiculous laws, so much to the point where walking in the street at a certain time of night can get your balls cut off (exageration ofcourse). Tieneman square ect?

Anyway, back on topic: Well i'm glad your having more success with yours. Only thing left for me to do now is to try and get mine to improve. Glad one of us is having a slight success story with HG currently

[StanChung]

My brother in law works in bank trading floor and definitely no cameras or handphones but I doubt they even allow tanks. This is intriguing.

[Verminator]

I suppose every work place is different Just intrigued to know what job he's in that does not allow cameras. No reason without justification, only then does it make sense...basically nosey haha

Alechim, might want to check here, this guys tank is 3 months low tech, no ferts, no wc and his HG is doing fair better than mine in high tech, with NPK dosing lol. ironic.

Added my HG grown in hightech with NPK daily dosing. 3 months set up

VS

No tech, no fert, no wc, little or no effort.

This goes to show life is not fair and there should not be any comparison.....

[StanChung]

Could be a different species. There's a japanese hairgrass that's ~50% slower and 1/2-1/3 the size of Eleocharis parvula.

This is the Japanese hairgrass, only 2-3cm tall.


and this is Eleocharis parvula.

[alechim]

mine is the normal HG, not the Jap HG.

Yeah its so unfair!

If you notice the height of this setup the water for the light to reach is very shallow, it get almost 100% lighting from this, generally the HG would have enough lighting to grow even if you dont feed any nutrient cause the new soil nutrient would last for quite awhile of nutrient supply to the HG before it runs out and there's no other plant that fight for the nutrient to grow. If you just dose K alone, it would grow wild and more dense than before. As K is always not enough for the plant, over dose of K would kill your shrimp, i mean really overrrrr... dose.

For your 48W lighting, this is not enough to make them grow, you need another 24W would be just nice, if you add another 24W you got to cut down your photoperiod to 8hrs, it doesnt mean longer hr of photoperiod is good for the plant rather enough light for the plant is the most crucial source of energy for the plant to grow. I'm currently running 2x24W T5 and 36W PL for 1.5x1.5x1.5 ft tank and i dont get major algae, just spot algae, and the Jap HG is growing crazy, also because i've alot of fauna, about 30+, so the fish food and poo is almost enough to provide N and P, now i only dose more K and some N(if i notice not enough). Notice you got quite no of fauna also.

And why Metal Halide is always the best lighting for the plant is because it has better and longer distance penetration of light, unlike the rest of the light. If you notice most of the shallow tank with normal light, the plant can still grow pretty well even if there's no nutrient added.

Yeah its so unfair!

Is not unfair but getting the right formula to work! I personally bought alot of different light to do the research on my tank, though it may be a waste for others but i gained to use the right formula through experimenting. Just go out and look at how bright the sun is and the plant is happy to have them shine at it.

[torque6]

So probably issue with light ? what i have is the japanese variant Eleocharis parvula. The light of the no tech tank is maybe around 9w height about 17cm, mine is 23cm with 12w, but the growth shouldnt be up to a stage of 90% growth rate in a span of 3 months.

Quality and Kelvin of the light do play an important role. T5, PL and fluorescent with same voltage give different result of plant grow. Especially the quality of the light, where it came from. I have 2ft fluorescent with arcadia light and also normal fluorescent with different lumens, 36W PL, 55W PL, 2x24W T5 with 10000K and 6500K Osram. All these give different result. Especially the Kelvin play an important role, but with those made in China given the same Kelvin will differ the result in plant grow. I have bought China brand and they come with different brand light tube inside.

[blue33]

Also things to take note is if your water is not clean enough you'll get bad result of plant grow. You can see the low tech tank only has few small little shrimp, so the water quality is the best. With high fauna you got to really maintain the water quality well.

I would advice to change the water twice a week of 30%.

blue33 - I suppose I have to dose again since wc will reduce the nutrients in the water column. Now I only have green spotted algae which is not a big problem. HG is growing better though not like wild fire. I had also since change my photo period to 4 hrs with 2 hrs siesta and another 4 hrs. Seems to be working

Blue,
guess in our cases, kelvin could be playing a major role. Unfortunately for my case, i have no idea if the 12w is within the 5500-6500k or less. It doesnt even state daylight on the bulb.

I have another illumax 24w 10k, but changed to 18w 6500k for my HC project.

[alechim]

Update Updates : Came back office after a 3 day break and notice my HG getting worst for some reason. I had change nothing but some HG are getting the dark greening symptom again.

I have 2 mesh of moss hanging in my tank but over the last few months they are "thining" and breaking off instead of growing densely. Anyone encounter such problem?

You may be lacking of Phosphorus!

Directly look at the 12 w tube when it is on. Since you have a 6500k, put it side by side and compare how white is the tube you have doubt in colour temperature.

A query, I am dosing KH2PO4. Its phosphate, but does it has the Phosphorus needed?
