I think it's a case of regular maintenance, l know what you mean about difficult to remove, it may be best to consider shrimps, ottos( cannot praise they little fellows enough) snails, and juvenile Siamese Algae Eaters once a aquarium is cycled Except maybe Purigen I don't add treatments at all as the fundamental causes eg too much lighting ,too little lighting , overfeeding, fertilisers lack of w/changes, dead leafs on substrate possibly amongst other things, will not be addressed You always have algae in some way it just a natural occurance but some of the fast growers definetly make a difference. IMO
