I'm trying to figure out what fertilizers would be appropriate for my low tech 55 gallon tank, and I'm definitely in need of advice. The more I read online, the more I'm starting to confuse myself. I *think* that getting dry ferts from GLA following either EI or PPS-Pro might be appropriate, though since I don't have CO2 I think I'd need a much lower dose.
The anubias and Amazon swords (the only plants currently) in my tank seem to have some deficiency issues such as some yellowing older leaves, pin holes and slow sword growth. At the same time, I'm also currently combating BBA in the tank with daily excel, frequent water changes, reduced light intensity and photoperiod, and started the occasional bleach dipping of some of the anubias. I'm wondering if the combination of fertilizer (or lack thereof) and lights is out of whack, so I'm hoping you can help me. The only ferts/additives we have right now are Excel, Flourish (micros), and root tabs. The BBA seems to be slowly improving.
55 gallon low tech (no CO2, just excel) using hard tap water treated with Prime
inert pool filter sand as substrate, supplemented with root tabs by the swords
0 ppm Ammonia
0 ppm nitrite
5-10 ppm nitrate (was usually ~10 ppm before adding more frequent water changes)
Lights: Fluval eco bright LED fixture (13588), currently on for 9 hours/day.
We also have two submersible LED strips that I think are Marineland Hidden LED Lighting System, 21" Length (not positive - got them secondhand from my husband's coworker). Until recently these were also on, but I realized that was probably WAY overkill on the lighting so they've been off for the last couple of weeks.
Plants: lots of anubias nana, one larger unknown anubias, one medium sized Amazon sword and two small swords. Definitely hoping to add more plants soon, but no more anubias nana. That one grows like a weed in our tank
I'm looking at possibly the Estimative Index E.I. Aquarium Fertilizer Package (Jars) pack from GLA, since I don't think I need the MgSO4 included with the PPS-pro pack due to our hard water. Though I wish I could find some without shipping charges. Does this seem appropriate? And if so, any suggestions on dosing? Thanks!
