I have a couple questions regarding my 29 gallon planted tank. I have been keeping Aquariums for years but have recently begun to plant my tanks. I am running a low light, low tech tank with a sand substrate that I dose with Flourish twice a week and Excel every day and have Flourish Root Tabs in. So far the planting consists of hygrophilia (polysperma, I believe), Amazon Sword, Micro-sword, and Anubias Nana.
First - My new hygros (just added a week or so ago) are all developing holes in the lower leaves. These leaves are all starting to fall away. What can I do to stop this?
Second - I currently run a T8, one bulb fixture. (Aqueon Flourescent hood light that is currently over a glass top). The bulb is going, and rather than buying another sub-par bulb, I am looking into upgrading my light. I am looking at the Finnex 24/7 Planted+. Would this be a good light, or should I instead get a T5HO fixture?
Thanks so much in advance!
