Soldato
I really am struggling to get plants growing in my tank. I have tried everything but to no avail. One of the major problems is that the tank is rather deep (45 cm or 1.5 ft) so it has been difficult getting light to the bottom. The standard light setup that came with the tank was a load of rubbish, so I replaced the tubes with Zoomed's max plant growrth (2 x 15 watt T8's) and this improved the situation a little. I then purchased an additional starter unit and added another 2 tubes meaning I know have 2 wpg. Whilst this has stopped the plants from turning brown and enhanced their colour to a nice dark green, they are just not growing very much. I have only had the extra 2 tubes in for about 4 weeks.
My tank is a 30 US gallon (115 l) setup with 2 x Java fern and 2 x Amazon sword plants. I must add that the Java fern seem to be sprouting babies which I take is a good sign but I really wanted to grow a nice jungle in there and it is just not happening. I really need some advice.
java fern and amazon sword aren't very light demanding plants so your lighting is fine. perhaps look at using some decent fertiliser, when I had a planted tank I used Seachem Flourish/Excel.
to be honest I never had much success with plants either, I even tried EI dosing and Co2 but failed to get good results, I put it down to us living in a very hard water area. interested to hear how you get on.
