Kay, first of all, beautiful tank and carpeting, super pretty german blues, I love the angel fish center piece. However you have a lot of fish = a lot of waste = you have to clean it really detailed or have a clean up crew.

I'm not an expert but try recruiting a clean up crew (shrimp, snails, catfish...nerite snails love brown algae) and take a look at your plants, each one of them, at Google, so you can actually understand about root feeder plants and water feeder plants.

Also, I think twice a week water change for this tank of yours is a lot and you a killing the cycle, but you have double filtration and a nice surface tension break so it might not be an issue. Try looking for "old tank syndrome" as well and make[censored]use of reverse osmosis or deionized water to change the water.

You are using co2, this is increasing the algae bloom as well, i dont know if you have it but to clean a tank like yours i would use the gravel washer tube, its really good for carpet cleaning, and you can actually focus in one point to make it algae free again.

Aquariums are closed ecosystems, just like any lake or any where in the nature, expect changes when you add, take or change things from the system, even if its a small system just like fish tanks, tropical amphibians, ant colony......its nature, and nature can give a lot and take back as well.

So think about this equation:
feeding a fish community + CO2 system + plant root systems + lighting + (rich substrate) x (fertilizers) = life explosion

First thing I would do: check parameters (once in the morning and again at nighr) for a new (big) clean up crew. Then check your lighting cycle (12 hours on? Make it 10, do experiments by yourself to check how your ecosystem works in regards of lighting, temperature and oxygentaion)

Keep up the efforr

Thanks for the response and tips.



Yes, I am aware of the number of fishes in my tank and unfortunately, I cannot do much about this. None of the pet stores near me adopt fishes. I know its a bit high, but I do have a cleanup crew. I have updated the details of my tank in my post.



My tank size is 45Gal # Fishes: 18, 10 serpae tetras, 5 Kerri blue, 1 Angel and 2 German blue rams

Cleanup Crew: 5 nerite snails and 4 otocynclus



I Don't do water changes twice a week all the time. It is only when I notice some significant algae growth. I am also not sure if I have a huge bio load. I feed my fishes just once a day. I do gravel vacuum using python system. Although, since most of my tank is carpeted, I try to just siphon things without disturbing the substrate.



I did experiment with lights as mentioned in my post. A month ago, I thought I almost got the balance. The problem I am facing is that if one plant does well, the other does not. For instance, currently Srepens, java fern and Amazon sword are doing well, but Rotala is doing very bad. I will do more experiments though.

You can have some improvements like a timer for the light and for the co2, both should be turn on at day and both turned off at night. My co2 system runs 2 times during light time, for 2 hours, total of 4 hours of co2 daily.

Also, during night time, an airstone could help oxygenation, put it on a timer as well.

I will send some pictures of my 20g tank (i ordered some carpeting seeds already) that have 6 neon, 1 german blue (his wife died from mounth fungus) and 1 dojo loach, also 2 rescued livebearers. A lot of snails and some ghost shrimps.

At the timer picture you can see the light cable at day and the airstone cable at night, and i did noticed my fish less stressed after the airstone addition.

At the last picture you can check my basic "plant kit", i have more stuff but this is enough to understand. I have root tabs, the substrate I mixed with the gravel and some wondershells for shrimps and snails shell formation and reinforcement. Also im using seachem plant pack lvl 1 for a long time now and hygrophila loves it.

My tank is a result of propagation, all the root system you can see is from trimming and replanting, the same with ludwigia and anacharis. Im using the root tabs for amazon sword, ludwigia and echinodorus, as well as my hygrophilla mother plant only cause they really got their nutrients from the water (thats why im enforcing it with seachem pack).

My filter is for 40g, with filterpads to make sure it can take care of anything I put in the tank. And a lucky bamboo for nitrates, but I dont like the idea of planting at the back filter.
