Yup - toMAto, toMAHto/wetland filter, bog... all the same thing.
And no - the pondless is in full sun for most of the day, but we've never had much of an algae issue. Being heavily planted is probably the best defense, but you could also try some hydrogen peroxide when the string algae gets too heavy. Shut the waterfall down, let it dry slightly and then dump or spray H2O2 all over the algae. (Just the plain old brown bottle kind you get at the store.) Let that sit until the whole thing dries and in 24 hours you'll see a reduction in string algae. You can also used sodium percarbonate - it's a powdered compound that breaks down into H2O2 and soda ash when it comes in contact with water. Same process - turn off the water, sprinkle the powder all over the areas that are algae come vered, let it sit for 20-30 minutes and then turn it all back on. Kills it off very effectively.
As for what type of plants you can use - they sky is the limit with a pondless. Any marginal pond plant will work. Reeds, rushes, irises, ground covers, sedums, floaters, annuals... there are tons!
You do need to anchor the new plants with rocks to give them a chance to get rooted, but once they do they'll do great. In fact you need to be mindful of the amount of growth, as happy pond plants can take over very quickly!
