Macro Algae you mean.
Micro Algae in the reef are generally problematic and very hard to prune and controll compared to macro's.
Just think of your cannister as a sump in and of itself.
Pack it with LR and leave a media basket chamber available for phosban or carbon or anything else you might need to run here and there down the line.
The mistake people generally make and refer to when talking about how these things can be nitrate factories is to leave thie filter largely setup for fresh water or fish only systems where the bio filtration is approached a lot differently.
Water changes are key though in a small system.
you could likely forgo the skimmer and filter if you just did a 5 gallon change every 2 - 4 weeks after the tank has cycled.
And other than having to make sure aggressive algae doesnt take over corals spaces, having some macro in the display is a great idea...just make sure you prun it properly or it will go sexual on you and in a 25 gallon, will likely choke everything for lack of oxygen.
