I noticed your last posted Ca and alk were 240 and 7 dKH. Have you dosed to adjust these numbers yet?
The red algae looks to be a type of Botryocladia spp. which can be a real nuisance or it may just go away on it's own. I'd keep a close eye on it, and in intervene if needed. The green tuft algae is Neomeris annulata and not usually a problem.
