Hygrophila Serpyllum, this is an amazing low light carpeting plant. Unfortunately, it's a truly rare plant and hard to find.

You have to fertilize the water column regardless of root tabs.

Could be limnophilia Aromatica. But struggling.

No, just spot dose it and can repeat every 24 hours. Get a syringe and use 15ml per 10 gallons. Turn off everything pump wise. Spot dose it and let it sit for 15 minutes or so. Then pumps on. Repeat the next day. Basically, paint across the worst areas.

Spot dosing hydrogen peroxide wrecks it, and raise Nitrates to combat it. Improve flow throughout the tank as well.

Your local brewery supply store will have nice shinny tanks. I also refill there as well.

You should use the ppm to calculate the ratio. ?ppm of Ca=?dGH, ?ppm of Mg=?dGH then add those degrees for total GH. So, 21ppm Ca and 7ppm Mg is a 3:1 (just an example).

Mg/L is also ppm.

It's not your fault, Seachem needs to label better.

You are probably low on all of them. You posted your nitrates are 5ppm. You will need to dose the water column heavier regardless of root tabs. I would push towards maintaining around 15 to 20ppm nitrates from the Easy Green dosing. After correcting the nutrition issue, you can move on to other issues if the plants don't improve. Nutrients are the simplest to get correct.

Ah okay, Flourish is just a supplement of Micros and almost no Macros. It looks like the plants are dropping lower leaves to support new growth. Unfortunately, root tabs can be misleading and a comprehensive water column dosing schedule is still needed. You will want to use an all in one fertilizer like Easy Green or NilocG. They're others, but these are easy to get.

I use a Chihiros WRGB 2. I don't think my current setup would be considered heavily planted. You can take what @Seattle_Aquaristjust posted a bit further and apply it to longer photo periods. There's another measure called Daily Light Integral or DLI. It's a fancy conversion of PPFD and LUX to DLI, but the simple explanation is how many photons plants receive in a 24 hour period. So DLI can be altered by light intensity and duration. Let's say any light is on for 1 hour at 100% intensity, and just for numbers sake, 10 was our DLI. If I increase duration to 2 hours and drop intensity to 50%, DLI is still 10. Again, these are not true numbers, but just a very basic example of how it works. The same number of photons are hitting the plants although the photo period is longer. So I'm using this strategy for the 11 hour photoperiod. I just keep dropping light intensity. I'm almost at my sweet spot and I'm right about at 50% intensity with this Chihiros. Disclaimer, I'm not smart and could have told you wrong, but this is my very basic understanding of DLI.

What does your dosing look like for column fertilizer?

Running 2 is a lot of light for sure. I would try 50% on both and just see what happens. Having 2 now will give you good spread for sure.

Sadly, I've deleted all my snap shots of my settings. All I have is a comparison shot. Not helpful for you but at least you can see the difference. Very old shot of my tank. Top picture is the double Fluval.

I had the same setup and ran them around 72% each, but I also inject CO2. Let me see if I can find my old settings.

I'm currently playing around with running my light for 11 hours and running a 1%, only blue, for another 4.5 hours. I have not noticed a difference honestly.

Bummer. Okay, so no it's not 100 when combined. There's certainly some crossover area that will be brighter than 50% so keep that in mind. Just FYI: Using Amazon pricing. 48 inch Fluval 3.0 $230.00x2=$460.00 Chihiros WRGB2 120 is $379.00 https://aquarockscolorado.com/products/chihiros-wrgb-ii-120-black?variant=39986628788390 The Chihiros is a much better light significantly. You would only need one for a standard 75 gallon. Superior contrast than Fluval and would grow any high demand plants.

Which stems? And you are low on nutrients based on the information you posted.

Did you already purchase the lights?

Nice, the exposure looks great! The tank is looking pretty darn good man.

Not sure, but it's an essential element they need to live.

100% safe for shrimp and snails. Fertilizer advertising no copper/shrimp safe is a gimmick. Shrimp and snails need copper to live.

Still need to get potassium, phosphorus and micros in there. Just a light fertilizing until the tank starts growing
