Ok, I'm pretty new to freshwater plants and I have a situation... I ran my 20 gallon tank for about a year down south with a couple anubias and java fern with no trouble under the 15W light that came with the cover and 2 more 15W in a double strip fixture from my old Eclypse system in regular city tap water, with about a dozen tetra, 2 cory cats, and one clown loach. Fish thrived, plants and algae fluorished. For the majority of that year I was not there and it ran at my ex room mates place where no maintenance was done other than topping off the water as it got low from evaporation. Finally moved the tank up north to my new place, set it up again with tap water, one of the bulbs died from the eclypse light so I just ran the one that came with the tank and canopy. Plants did fine throughout the cycle process, but then after about 2 months I started seeing the new leaves coming out pale, to the point of almost being white, and then growth seemed to simply stop. Just before this occurred one of the anubias put out a flower. I bought new plant spectrum aruarium bulbs and am running all 3 again, but have still had a leaf or three come out white here and there. After a lot of reading, my conclusion is iron defficiency, and I think adding iron and trace element supliments should resolve the issue and get them growing and greening up again. Can you all tell me what you think? Am I on the right track now? I'm also lookingat a longer term resolution, iron impregnated plant substrate, but want to be sure this will be worth the expense before doing it.
