Just got a bunch of different anubias for my 55 and seeing some of the leaves on a few of them turn yellow/brown/ almost black. They've only been in for 5 days. Running 1 t8 daylight bulb on it for 8 hrs a day and have dosed flourish once during this time period. I think the anubias in question are the lanceolata and congengis species.. They are wrapped around rocks with rubberband

A lot of aquatic plants do that normally. Some are because they were grown emmersed at the nursery (faster production in air rather than water) and the leaves will not work submerged, some are just not healthy while in the store tank and others do that just because the conditions in your tank are different enough. I had swords with brown leaves that kept getting worse but all the new growth was fine.

I haven't tried anubias yet to know what they do though.

Did you plant them or are they still rubber banded?

Can you post pictures? Perhaps it is something else and a picture can clear that up.

Others will ask about the water parameters, GH, KH and pH... maybe temperature.

I know for one thing that they were grown submerged. Temp is 76/77 DH is 11 not sure what my Kh is and ph 8.4. Would have to put up pics a little later and oh yeah they're still rubber banded around rock.

Would also like to throw in that these plants are also shaded with floating plants,sickening to have to cut off an anubias leaf as we all know it will take weeks for another one to grow back

That's not from being introduced into ya tank. Anubias don't normally do that unless there is something there that is missing.
The Flourish you are dosing is it Comprehensive Plant supplement??
How is the Rhizome on the plant? Is it crushed or buried?

How could a root tab benefit it when it's not in the substrate? I thought anubias got its nutrients from water column. On the light issue I've been told a single t8 daylight bulb is more than sufficient for anubias . I'm using just the cheap GE bulb though. I could put in a life glo bulb if that would be better. Should I bump my flourish dosage to 2 times per week?

It can't, it's not a substrate rooted plant.

The light needs to be a 6,000k to 7,000k bulb. A cheap GE bulb probably isn't good enough. I'd suggest doing the bulb change before adding more fertilizer... Others may have other ideas on that though.

lol foot in mouth, just took a guess by the leaf pic it was a rooted plant. guess thats what happens with assumptions. i do agree though with the light idea. plants need everything in balance. yes there may be light but not the right spectrum for them to absorb resulting in what your seeing now.

The bulb I'm using is a brand new 6500k GE bulb but I could go to a 6700k life glo 2 that's more intense

You say this is one bulb right? Is this a 48" bulb or is it shorter?? 6500k is fine. If you are running one bulb the lenght of the tank that is enough light for Anubias. Even 2 bulbs that are 18" that come in the standard hoods for a 55 gallon is fine but one bulb thats shorter then the lenght of the tank may not be.

200 kelvin is not going to make any difference, the rating is the peak of a curve, not a point. If the light is not intense enough, a larger diameter bulb perhaps.... If what you have is a new bulb, even though it's nothing special, it should suffice, but I'm an LED guy, so don't quote me on optimal fluorescent lighting.

Maybe take a shot of the plants in the tank too, see what is healthy and what isn't.

This is past anything for me to help with. The concern is hat this happens fast, 5 days. a slow gradual die off is not unusual and it allows for new growth to start and take over. I had that with my swords... after about two months they are all new post store growth.

3 leaves total 2 on one and 1 on another. They were tiny leaves. Not really seeing any new growth . New amazon swords are growing plenty of new roots on the baby plantlet and my older amazon sword is still shooting up new growth

I think I found the problem . Both of those plants are VERY close to my heaters. Could it be burning the leaves?
