Background: 75P ADA tank. Just got new lighting fixture from Catalina, lighting fixture is about 10" wide and has 3 bulbs. It's a 30" fixture but the bulbs are all 24" T5HO. The bulbs are also staggered within the fixture. I have 2 of the bulbs(the outside bulbs) on for about 10 hours, and the middle bulb turns on for about 6 hours in the afternoon. My dosing schedule is modified because the tank is fairly new and the plants I got I think take a little while to acclimate to submersed life and haven't really taken off yet. I can't really call the tank heavily planted for this reason. The plants I have are Anubias nana petite, C. Helferi, Narrow leaf Java Fern, and Glosso. I dose 2 times a week in this schedule. Monday I do a 50% water change and after water change I dose 1/8tsp KH2PO4, 1/8tsp K2SO4, and 1/8tsp CSM+B. I keep an eye on my nitrates before dosing KNO3.....right now my nitrates are sitting around 10ppm and for this reason I have not dosed KNO3 for about 2 weeks. The tank substrate is Amazonia II from ADA. This is the 4th week of the tank being set up. I have no fish or livestock of any kind yet. I am seeing quite a bit of algae at the moment. I see some of my algae is because the tank is new and it's just your average diatoms, but I am also seeing hair algae now as well. It's not bad, but it's there....mostly on my Anubias Nana petite. Also, I have noticed one new leaf on each of the three Anubias Nana's and each of those leaves are a nice bright green, but the edges are brown, like they have been burned? Then I started really looking and it looks like that on the new growth of the Glosso. All the new leaves look bright with a brown tinge on the edges. The Glosso was growing vertical but now that I have a new Catalina fixture that I received on Monday, so it's only been up and running with the new light for a few days. I am hoping the Glosso starts to grow horizontal now.....Is there something I am missing? Why the hair algae, and what's with the burned leaves look? I read maybe it was because I had the anubias under low light conditions and then placed them in a tank with this intense lighting and they might just be getting used to them.....Thanks in advance for any help.
