Can you post a photo to confirm? Worst comes to worst, you may just cut those affected leaves.

C兄 幫幫我
如果有黑點就要剪 差唔多要剪晒所有葉
會唔會唔夠肥料呀 ?

Those are not black spots but Green Spot Algae. Increase the supply level of CO2 may help a bit. For those that are already on the leaves, you can only remove them manually.

唔該晒
但係我冇用 co2 ga
咁即係新葉 過一段時間又會生綠藻 ?
咁咪會剪到成棵冇晒葉?
咁冇 co2 咪即係連水榕都養唔到
水榕係最易養 都養唔到 咁咪要掉左個缸

Is it true that "手擦唔甩既"? What about using a brush to clean them (gently)?

唔一定要剪o既...
(1)你可以買隻鮑魚螺/角螺食左佢。
(2)由得佢啦，慢慢d水靚返，水榕又長d新葉就冇o架喇!!

c 兄
掂呀 !!
我用牙刷大力 d 擦得甩
唔怕擦傷 d 葉掛 ?
咁我以後只可用尼個方法 ?
除左用 co2 有冇野可以預防生黑點呀?
求先 差 d想 開窗掉左個缸落街
多謝你幫忙

我唔用螺 ga
睇 post 話要刷螺蛋 好麻煩
多謝意見

maybe you can try to increase PO4.
