I am not much help as I am still new to this. I have a 55gl too as well and I have algae growing. I have a snail so I welcome some growth. LOL I get to focus more on giving the snail treats this way.
This is what I have been doing. It is right? I dunno but it works for me. I do this with my 10gl tank as well I have had it up for awhile now.
I am on a schedule. The algae part... I have seen scrappers etc at the LFS
, but I went with a little green pad and it works great.
Every two weeks I clean off the front glass. It has a film on it, and I know there is good bacteria on there too so I dont do the back glass as often as a bubble curtain hides it When I do the back wall I will NOT do the front. That is alot of glass surface if you think about it with some good stuff on it too.
I may skip cleaning off the glass and will during a PWC
take out my fake plants gathering the "fuzz" as I call it and I will clean off only the areas that have fuzz in the PWC
bucket, so I dont kill my bacteria and I leave most of it alone. Just get the yuckies.
I am all over it in a schedule and watch it. I want it for the snail but I dont want a ton of it. I dont want to add something to kill it as I like to add as little as possible to my tank.
That is what I do.
