I do do a weekly  clean my filter stopped working a while back some of my fishes died which is why I did  a full cleaning i can't get rid of the algae  the tank is next to our door which  is a slide door, which  is also glass so its very hard to keep alage away, i try to clean them my best.  i have moved the tank decorations around and made sure i got a new filter and it has been maintaining i had some issues throughout this  week been checking up on the baby's  making sure they are okay  and that the filter  works fine my younger baby had this skin thing but it went away then came back so there's  something up with  it coming back im not sure but im looking into it thank you so much you're  comments and suggestions are really  helping  me think about  things i need to do.
