Hi, i have a planted 40 gallon tank. My question is, is there anything wrong with having algae in your tank? I have a fair amount of black beard algae and green hair algae in my tank, which i dont mind the look of. None of the plants are melting and the water quality is fine. Was wondering if there is any reason i shouldn't just let it grow. Thanks in advance.

Some people do like Algae growth on their tank, and others don't

I used to try and get my algae to grow, but the only thing is now... my entire 10 gallon tank is loaded with algae and it is hard to take off, so I don't bother with it anymore, and my fishes are fine, nothing bad that the algae is actually doing anything anyways.
The thing is that phosphate causes algae growth, and with out phosphate the algae won't be able to grow

Laundry Detergent used to have phosphate until the 1970's when it was banned because the lakes and rivers would be loaded up with so much algae, bulldozers had to take push them all out. So I guess that was good now

although I have heard of some plant fertilizers that have phosphate but I bought fertilizers with phosphate before, and nothing really bad happened. If you have a lot of plants, algae shouldn't be able to grow because plants absorb a lot of the phosphate and all of the other nutrients that the fertilizers have
