I’ve been looking for a solution to algae control in my 20 gallon tank. I have heard that you can’t put a plecostomus in with crayfish because the crays will eat the pleco. I do have an algae scraper, but nothing is as good as the real thing. On all the chemicals I have checked, they say not to use with crustaceans. I don’t want to have to scrape the tank every week
, but I will if there is no other solution. With pleco, it is a lot more effective. Thanks for the help.Reply:
Try a good cleaning, scraping as usual, then reduce your lighting hours per day to 6 hrs., or just less than you are now.
