I have a Brackish tank (1.010 sg) with 2 Ceylon Puffers in and have a fair bit of algae (both the hair type and surface covering type), any ideas as to what I can do to get rid of it? Would prefer to use fish/inverts not chemicals.
Cheers

Not too many algae eaters that like mid to high brackish (that are readily available, and puffer compatible).
What are you tank parameters...Nitrate, phosphate, iron in particular
How often do you do water changes (and how much)
Best solution (IMHO) would be to increase your water change sched...and get the nutrients causing the problem outta the water column. Reduced feedings, vacuum gravel, clean filters, manual removal of the algae will all help...but if you don't address the cause it will keep coming back
The addition of a of a phosphate, and nitrate absorbing resin to the filter may also help (if this is the cause)
At that specific gravity your options are pretty limited. Mollies would eat some of the algae, but certainly won't be pleco-like. As jackknife said, a phosphate binding resin (or even better a reactor) should help as will more frequent water changes.
If you like plants, Widgeon Grass (Ruppia maritima) is the plant for brackish aquaria. Widgeon Grass is fine in any conditions really, from near freshwater to even hypersaline. A refugium with a DSB of at least 4" and plenty of light would certainly be an algae killer. Also, macro algaes such as Sea Lettuce (Ulva lactuca) and Chaetomorpha (Chaetomorpha sp.) are fine mid range brackish water.
As Norway Reef suggested, Mollies will eat some algae, but they will only pick at it in-between feedings, they will not eat enough to make any visible difference.
Your plan sounds good. Get back to us if the algae problem doesn't improve.

Prevent unnecessary deaths due to disease- quarantine ALL new additions at least 4 weeks in a separate tank before adding to your main display tank!
