Unfortunately… Depending on your source, ghost shrimp tend towards being very fragile. They’re often bred as feeders, and in bad conditions. I’ve only ever had them thrive occasionally in VERY well-established tanks.
For the algae, same advice I always give. Shorten the light cycle – you can also, if you have a good timer, introduce a break in the light cycle. Run the lights for two hours in the morning and three in the evening or something. Keep up on your water changes. Are you dosing liquid ferts? That’ll just be algae food right now. Manual removal for what’s possible… Getting it off plant leaves is better left to in-house cleanup crew though in my opinion. In my experience, mystery snails are actually very good eaters of hair algae. Adding a dime or nickel-sized one could help get things under control, but you should account for the fact that you may not want the full golf-ball sized individual in your tank once it stabilizes, as the adults can be a parameter hazard in and of themselves at times. A nerite snail would also not go amiss here as an alternative. They work a bit slower, but still eat hair algae okay, and are very thorough. Good luck.
For the hair algae, get a plastic syringe and fill it with hydrogen peroxide. Give the base of the algae a spritz everyday. This won’t take long. When it starts turning purple you know it’s working.
It’ll be “gone” within a week. Although this is one of those things that will keep coming back for a long time. Be diligent and kill it with the hydrogen peroxide whenever you see it coming back while you identify long term solutions to get your water right.
I would do the following:
1- lower your photoperiod to 6-8h per day. Buy another timer if yours does not permit this.
2- scrape the algae of your glass and do a 20% water change syphoning all the gunk above your substrate and removing any dead leaves you find. Manual remove as much algae as possible while at it.
3- 1 or 2 days later lower your water level as much as possible (keep a few inches for your fishes) so you can expose your rock decoration (keep that water on a bucket and let your filter running on it). Take a brush and paint some peroxide 3% on your rock and on the algae (avoid as much drip as possible on your water) and leave it there for 15minutes. Refill your tank with 80% of that water in the bucket and fill the rest with new water.
4- Up your husbandry game! More frequent water changes (20% every other day) and manual removal of any algae you find while doing it.
Considerations:
1- always use prime or similar after water changes.
2- you will need to test amonia regularly, specially after the peroxide bath (all the dead algae will probably raise your levels, so thats why manually removing as much as possible before this is important). Do water changes if your amonia levels are increasing.
3 – step 3 should be done carefully to avoid temperature shocking your fish. Make sure your room temperature is similar to the tank water. Use your heater in the bucket. Use as few peroxide as possible since it can harm your live stock and beneficial bacteria. Removing your live stock and putting it in the bucket may be safer if you can catch them easily.
Next steps:
1- now that your tank is cleaner, focus on prevention: try to feed less and buy more easy growing plants. More plants = less space for algae. Clean up crew (siamese algae eater, otocinclus, shrimps and snails are my recomendations) may help you as well.
2- hopefully your tank will grow less algae after that and you can slowly climb back to weekly water changes.
3- if your tank continues clean, slowly climb your photoperiod (30 or 60 minutes increase every 2 weeks) until you see some algae coming back. Reduce 30min and leave it there.
Your problem probably took weeks or months to evolve and you should accept that it will take some weeks to put it back together. Dont hurry and good luck!
I work for a big box pet store (but just put in my notice cause the job broke me lol). I order 50 ghost shrimp every single week. They come in on Wednesday and the he vast majority of the time about half are dead when I pull them from the shipping box. By Thursday I am lucky if I have more than 10. I have no idea how they fare when they go home with folks but I am pretty sure it’s not good.

Looks like you need another pH test that test for the lower end. Do you have a nitrate and a phosphate test? Do you use fertilizers or CO2?
