TMartins Posted October 18, 2021 Share Posted October 18, 2021 (edited) Hello everyone, I’ve had Valisneria in my Aquarium that I bought from the Co-Op a few months ago and for some reason it never grows tall. It sends out plenty of shoots but stays low. I have a Finnex Fugeray Planted Plus light, Nitrates around 20 ppm, pH 7.4. I dose with Easy Green and use ACO Root Tabs.

Colu Posted October 19, 2021 Share Posted October 19, 2021 (edited) it can take a long time for vallisneria to get going in some tanks for not apparent reason I have had it spread like wildfire in some of my tanks be really slow to get going in others it very hit and miss I would give some more time Edited October 19, 2021 by Colu 1 Link to comment Share on other sites More sharing options...
Griznatch Posted October 19, 2021 Share Posted October 19, 2021 It took my jungle val almost 6 months to start noticeably growing... then, boom it took over... 1 Link to comment Share on other sites More sharing options...
Blaha Posted October 19, 2021 Share Posted October 19, 2021 Mine was in my tank for a couple months and it sent a few runners, but never got above 2-3 inches tall. Then I switched to a Fluval light (unrelated, it was for other plants) and after a couple weeks the youngest runners started growing but any of the sprouts over a month old hasn't grown taller. It could just stay short in lower light. I'm not familiar with your light to know though 1 Link to comment Share on other sites More sharing options...
lefty o Posted October 19, 2021 Share Posted October 19, 2021 it can take a while for it to be happy and grow. 1 Link to comment Share on other sites More sharing options...
anewbie Posted October 19, 2021 Share Posted October 19, 2021 Not sure that is actually italia val (it is definitely not jungle val). Looks more like pygmy sword or dwarf sag. 1 Link to comment Share on other sites More sharing options...
TMartins Posted October 19, 2021 Author Share Posted October 19, 2021 It was definitely tall when I purchased it. I do have a light that is considered “high light”. Link to comment Share on other sites More sharing options...
anewbie Posted October 19, 2021 Share Posted October 19, 2021 Not sure; you could try turning the light down a little. This is mine (italia val); jungle val is more like an inch thick leaves - i have that in my 120; my substrate is inert (like yours); my water is gh 7 kh 3 ph 7-7.1. You could try some root tabs (i use two or three every 3 or 4 months - so no too frequent or too many): 1 Link to comment Share on other sites More sharing options...
anewbie Posted October 21, 2021 Share Posted October 21, 2021 I wanted to follow up this - i was watching the italia val in my black 29 (not picture) as it recently sprouted and noticed you didn't mention a time line for your plants. You should not be surprise if it takes 2 to 4 months for them to reach the top in a low tech aquarium. Link to comment Share on other sites More sharing options...
