The endler guy

how should/ should I do a water change because I have shrimp (and shrimplets) as well as newly born endler fry (I did a test today and the parameters are 0 NH4/3, 0 NO2, 0NO3)

sure ill stop using the marine land and do water changes and see how it is in a few weeks! Thanks!

I run two lights because the marine land is abysmal (worse than a light that comes with a kit) and the other light is to grow plants, it doesnt reach the front so I use the marine land (I may as well, I spent $60 its not like im going to not use it) to illuminate the front. I dont dose fertilizers besides root tabs, and being real I dont do water changes unless my ammonia or nitrites are elevated (but I do test weekly).

As of a few months ago I have had a bad algae problem please help ID so I can better combat it, here's some info on the tank 40 breeder 75 gallon sponge filter 5 gallon sponge filter https://www.amazon.com/NICREW-Freshwater-Aquarium-Light-Spectrum/dp/B08SC4DYN1/ref=sr_1_9?crid=XUH9G37NINEY&keywords=nicrew%2Bled%2Baquarium%2Blight&qid=1655485463&sprefix=nicre%2Caps%2C72&sr=8-9&th=1 (light) https://www.petsmart.com/fish/heating-and-lighting/lights/marineland-led-bright-lighting-system-16480.html (second light) stocking ( + or - some shrimp) (and endler fry) (and Im not finished stocking have to up schools and such since many are survivors of my first tank) 3x Panda Cory (Corydoras panda) 4 x Neon Tetra (Paracheirodon innesi)4 x White Cloud Mountain Minnow (Tanichthys albonubes)2 x African Dwarf Frog (Hymenochirus boettgeri)1 x Peppered Cory (Corydoras paleatus)1 x Red Cherry Shrimp (Neocaridina heteropoda)10 x Cherry Shrimp (Neocaridina heteropoda)1 x Nerite Snail (Nerita sp.)5 x Endler (Poecilia wingei) lights where on 8 hours with the marine land on for 9 (its an abysmal light worst $60 ever spent) I did have an out break of hydra about a month ago treated with no Planaria haven't seen any since parameters since I got the tank in a google spread sheet (https://docs.google.com/spreadsheets/d/16UK8a2AfMVECLHKoTSaUJgTGwcMM_AnGU4rpGdVpf50/edit?usp=sharing) any help is greatly appreciated!
