RTL growing very tall

[Siang Chaw]

Hi All,

Would like to seek some help for the above mentioned. I carried out water change once every two wks.

Tank
2X1X1 ft

Light
72PL

Fertilizer regiment
alternate between E15 and V30 as describe and A1.
nitrogen and phosphorous and K from Seachem, 1.5ml twice weekly

Is there any other nutrient that the tank is lacking which caused my RTL to grow to the water surface?

Any suggestion is deeply appriciated.

Regards

ib have read from previous posts that others cut the leaves off to induce smaller and shorter leaves not sure about it though. You can try but dont cut too many at a time

New leaves will always try to grow above the older leaves to get more light. The trick is to trim off the tallest leaves... but as Phillipians said, make sure you leave 2 or 3 medium sized leaves intact. You will probably have to keep trimming every 1 or 2 weeks, but it's easy to trim.

Thank you for the reply

Will take note on that. Was at Nature this afternoon and spoke to Mr Chan about it, but according to him, my tank may be lacking in some nutrient but I didn't manage to talk to him in details as the shop was quite busy today. So, can anybody shed some lights into what nutrients is lacking? I also notice that my Japonica Blyxia isn't growing well too..

hmmm i doubt the reason for your RTL growing tall is because of nutrients, it could be light btw whats the wattage for your tank and the tank specs? and also whats happening to the japonica? leaves turning brown? if so , either lack of light or iron. Do you dose your tank?

[Phillipians]

hmmm went up to re read your post realised that well your tank light specs is rather ok, sufficient. So dont worry about it, i think its your dosing regime, do you dose Fe, i m not sure what is the stuff you are dosing now, but check whether there is sufficient Fe in your tank

I don't think it's a lack of nutrients. Rather, I think it's a natural thing for the plant to do? I've seen RTLs with leaves floating on the surface and emersed flowers and all that. Although I've never grown a RTL before, I'm pretty sure that it happens to everyone who grows a RTL.

Of course, I can be wrong

i have had one before but it did not grow to the extent of reaching my 1.25 ft ht tank. after 1 mth plus it was only like a little more than half a ft. anyway try out the other method, trim off some of the higher growing leaves than see what happens shouldnt be a prob.

waterlilies (which is what the so called "tiger lotus" really is) have two kinds of leaves and these are morphologically different. one is meant to float and have waxy coating on the top to prevent drying, whereas submersed leaves would dry if you leave them out o the water.

you can see both type of leaves here (scroll down the replies there is one showing both submersed and floating leaves, and another showing underside of the floating leaves, see page two for the flowers) http://www.aquaticquotient.com/forum...ead.php?t=9062
