Dwarf Sag, Metricide, And Dosing

My dwarf sag is melting and I know some melting takes place when newly planted, but my other plants as you'll see are doing much better. Tank was cycled and currently been running 11 days with fish and plants. Just did 12g water change yesterday.

Tank details: 40 gallon breeder, 40+ lbs. CaribSea eco-complete planted substrate on top of 20 lbs black sand, Finnex planted+ 24/7 light on 24/7 cycle and it's 16 inches above substrate, easy green liquid fertilizer 2x weekly, Aqueon quietflow 30 and aqua-tech 10-20 filters, 13 zebra danio, 5 tetra glofish, 4 green cory cats, 4 amano shrimp, 1 mystery snail, 0 ammonia, 0 nitrites, 20-maybe 40ppm nitrates from apI test kit, 7.6 pH, kH is 80, gH is 180. I also just ordered Metricide 14. I threw out activator and calculated what to dose based on excel chart.

Questions I have are as follows:
1. Why are dwarf sag melting as in pictures? I had 23 healthy plants and they look like crud now.

2. I plan to dose 2.75mL of Metricide after water changes and then 2.2mL other days of week with 1 day of our no dosing. How does that sound?

3. What instrument should I dose with? Should I get a dropper from the store? I have 1 gallon bottle of metricide.

4. Are gloves necessary and will it hurt my anacharis still if I dose at other end of tank?

5. Are my other parameters and liquid fertilizer dosing good?

This is a loaded post, but I know these things are all woven together as is many things in an aquarium. Fish, shrimp, and snail are active, healthy, and happy.

Thanks Everyone!!!

 

That's pretty bad. Dwarf sag shouldn't melt like that. If you are bombarding your tank with light but not backing it up with sufficient ferts and carbon your plants will perish and algae will take over. Cut the photoperiod down, dose a complete fert, dose carbon, give your plants a chance to recover before you start increasing light.
I use pipettes from the art store, it's for mixing food colouring or suchlike.
Pic shows my dwarf sag in crappy LED lighting that's on for less than five hours a day. I double-dose liquid carbon in this tank, splitting the dose - once in the morning and once in the evening. IME plants are more likely to be deficient in carbon than anything else.

 

Wayyyyy too much light, cut it back to 12-16

 

16 is even a stretch

First off, thanks for the reply! Yes, that's what I was hoping it would look like. Should I take out whole plant of dwarf sag if all of it is melted or cut off melted and leave roots?

Is Easy Green liquid ferts 2x a week enough?

Is my liquid carbon enough (aka metricide)? It says 1mL per 10 gallons for excel and since metricide is about 1.7 times as strong it came out to 2.2 mL and I figured I'd dose a little more after water changes. Should I take a break 1 day or not for metricide?

Thanks!!

Is it too much even if it's the blue light at night 2-6am and low PAR light 9pm-2am and 6am-9am. Max lighting is like 12-5pm or so with medium low PAR 9am-12pm and 5pm-9pm. That's just what the 24/7 cycle does. I don't have a timer as of now so when I leave for work should I put on max light and turn it off 12 hours later?

 

I don't know what any of that means! I would go for medium light at 6 hours a day and no light the rest of the time. The light is killing them.
Dose the carbon every day, it degrades in 24 hours anyway.
I think you have enough ferts since your plants aren't growing atm, you can revisit it later.
ukaps.org is a good forum for plants.

 

Yeah- less light would be good.

 

Thanks for the help! Will also be trying some iron and maybe potassium if necessary down the road.

 

Scratch the potassium, easy green has plenty. I did order GH and KH testing kit instead of strips. Also ordered Seachem iron and iron test kit. Light has been cut back and will update any new developments in the next week.

I now leave my lights on about 12-13 hours a day of 24/7 cycle and that's it. I also switched to dry ferts and plants are loving it! They are growing like mad! Once my emersed carpet I'm growing in another tank is planted I'd love to know your opinion of tank. Not great aquascaping, but as an initial planted tank.
