My Rotala Rotundifolia has been looking pretty bad lately. Stunted and dying old growth. Not able to figure out what to do to fix it.

Tank Specs
20g High
Finnex Planted +24/7 at max from 3pm-9pm
CO2, Paintball, turns drop checker lime green, on from 1pm-7pm
Substrate, ADA amazonia, 19 months old, (Age Maybe?) added root tabs
Ferts, NilocG DIY EI Macros and Micros (Extra Iron as well)
Filter, Marineland Penguin 150

Ok, I don't know about fertilizers, but it does look like there's a deficiency of sime kind. I couldn't imagine what given the ferts you are dosing. But I do know about algae lol, is there algae? If it's diatoms, they seem to hinder growth and becomes a problem on older leaves imo. What is your water change schedule? Have you rinsed the filter recently?

Could I be overdosing? Most of the algae is green hair on my hairgrass and moss.

In my experience, hair algae happens when I have too much light and fluctuating or not enough co2. I still call that too much light, since dialing it down has helped for me. Albeit I have to keep plants that will grow under less light. But I'm sure it could be caused by other factors. Sorry I'm of no help there, but hopefully at least get this going. Do you have a regular water change schedule? I'm pretty sure a weekly 50% water change is suggested when using Thrive.

50% weekly, think hair algae is from weaker hairgrass from older substrate.

I could try turning the light down tho. Nothing to lose at this point, planning to redo it at Christmas .

Idk, Just if you are seeing green algae and you won't be supplementing with pressurized co2, I think you'll have to lower the lighting until the low light plants fill in an outcompete the algae. (You might not be able to grow hairgrass very well with lower light though, so I would at least add an easier plant like tennelus or stargrass to use up nutrients).

Lighting is the driving force, the gas petal, the higher the light, the more ferts and co2 is needed. I found out I have to keep my lighting low enough not to cause algae. But I also can't grow any plant I want to and have to use easy low light plants like stargrass, dwarf sag, tenellus, hygro rosenervig and other varieties. Rotala rotundifolia is another good low light plant, so I'm hoping once you get a handle on the algae, it'll start growing nicely again.

I think you need an expert here! Vishaquatics Can you help?

How often are you dosing the NilocG EI macro/micro mix? I had a client of mine using that. I absolutely hated it (with exception to the micro mix) and once they switched over to dry ferts and my dosing schedule, it did much better. Now that you've probably exhausted the nutrients in the substrate, it's up to the liquid ferts to take care of the rest. The rotala shows clear macro deficiencies (nitrogen the most likely). This makes sense because the dose of macros from the bottle is very low.

I recommend buying dry KNO3 and KH2PO4 from nilocg. A pound of each should be fine.

3x a week, dose 7.5ppm NO3 and 3ppm PO4 on each dose using the rotalabutterfly.com calculator. You could use a teaspoon and just spoon in the dry amounts every morning.

3x a week, dose the micro mix according to the bottle. How much extra iron are you dosing?

Dose macros and micros on alternate days. Do a 50% water change at the end of the week.

In terms of your CO2, how is it diffused across the tank? It just looks like it's reaching the top like an airbubbler. If so, this needs to be addressed immediately. The CO2 should be blown evenly around the tank via a circulation pump. Once you get circulation down, continue increasing the CO2 every week until the algae goes away. If you keep up with ferts and water change, the algae should be gone and growth should be thriving

Thanks Vish. I'm on my last bottle of micros so what would you suggest for micros? NilocG preferable so I only have to place one order. Would Plantex CSM+B work for micros?

I use Plantex CSM+B. It's good stuff, but don't overdo it. I only recommend .25ppm of iron from CSM+b for every dose. If you need more iron, 11% DTPA is the way to go even if it's a bit more expensive

Do you feel that K2SO4 is necessary? I've seen it in other EI packages.

It’s not. The K from KNO3 and KH2PO4 is sufficient

I'm no plant expert but my rotala grows great. All I have is a nicrew light, eco complete, and really hard water. That may be it but idk.
