Glass scraping frequency?

[peewee5779]

Looking to find out how ofton an established tank (say over 3 years old) needs the glass scraped. I know this will vary with each tank and situation but I just wanted to see the responses. I usually do it once a week. Does this seem like too much for a 3 year old tank that is thriving? What are your thoughts?

I do It about every two weeks

When my tank was actually in one spot for 3 years about once a week. Just, when I noticed. Depends a lot on your own threshold for considering it dirty.

In the big tank that inherited 90% of that tank's rock but is really only a year old, about twice a week. Since I started carbon dosing in January, every day. Sometimes twice. It'll taper off eventually.

Mine I do about once a week-ish. Interestingly, I get way more algae growing on the glass when my phosphate starts to get too low. I take it as a warning sign to dose some more PO4. Every time I've thought to myself 'gee the glass is getting dirty quicker this week', a quick phosphate test has always revealed a PO4 concentration much lower than my preference

Scraping? Like Coralline algae, thick film algae....monthly with a razor.

Using a mag float type scraper, about once a week....but if I did it daily, I may not need to razor scrape monthly.

Yes just the soft stuff, I guess because I do it once a week I don't have problems with the coralline algae

I probably scrape off coralline every month or 2, and I probably do film algae every 4 or 5 days.

Yes that is the term I was looking for, film algae, thanks. Seems to be pretty normal for the film algae to come back quickly. Unfortunately I OCD about it

I never could make any rhyme nor reason why some algae’s grow daily and other don’t and this varies by time and tank…
usually when a tank is “ cooking” you should see pink specks on the glass within 12 hours of scraping …. no kidding
