How to get rid of algae in tank?

Question

How do I get rid of algae in a tank that has live plants, aside from doing a complete make over of the tank to remove affected items? I have green/black algae that grows on plants, rocks, driftwood, and the sides of the tank very close (reminds me of lichen, if that helps). I have otocinclus and bristlenose pleco algae eaters but there's only so much they can do. I don't think they can eat fast enough to outpace the algae, assuming they even enjoy this type of algae (although they always have full bellies and I don't give them algae wafers).

I noticed something by Jungle Labs called "Pond algae relief." On the bottle it says it's safe for live plants, although the description on the website says it isn't. Can I use this in an aquarium and would it be safe for live plants?

Oh, and I have reduced the lighting, but of course I can't reduce it too much or I risk killing the live plants.

1.Feed Your Fish Sparingly!
One of the most enjoyable times for the new hobbyist is watching the flurry of activity in the aquarium after that pinch or two of fish food hits the surface. Sometimes we're tempted to repeat the show 2-3 times a day, which is fine if your fish consume all the food within a couple minutes. The problems start if there is excess food, which is defined as "overfeeding." Overfeeding is the most common source of the algal nutrients ammonia and phosphate. Algae thrive on both the nutrients generated from uneaten food and fish waste. Many experienced hobbyists who learn to resist the feeding frenzy and only feed once daily - or feed smaller portions 2-3 times daily - find it's much easier to keep the unwanted green in check.

2.Control the Lights
If you turn on your aquarium lights when you wake up and turn them off before bed, the extended light cycle may be encouraging extra algae growth. Put your lights on a timer to replicate a day/night schedule and stick to it. Keep lights on 10-14 hours per day for planted aquariums, 6-10 for ornamental setups. Also, change bulbs at least once a year. Aquarium bulbs lose their spectrum and intensity as they age; this weakened light will likely encourage algae growth.

3.Frequent Partial Water Changes
In nature, rain and water currents refresh water conditions by diluting and carrying away nitrate (a.k.a. algae fertilizer) before it can build up to excessive levels. Your closed aquarium system, however, requires regular water changes to remove excess nutrients. Ideal frequency is 10% weekly, but for a lightly populated aquarium, 30% monthly is sufficient. It's also a chance to siphon up all the sludge and dead plant matter in your gravel.

4.Test Your Tap
It is a good practice to test your tap water before changes, because it may contain algae-encouraging elements right out of the faucet. If the test results show significant levels of phosphate or other algae inducing elements, your battle against algae via water changes will be futile until they are reduced by an RO unit or a tap water filter.

5.Maintain Your Filter Media
Keep algae's favorite nutrient out of your aquarium with phosphate controlling media and biological boosters for your filtration system. The right choice of filter media can make a big difference in phosphate levels: Drs. Foster & Smith PhosPure® Filter Media will remove phosphate and heavy metals. Combination Carbon-Phosphate Remover products are also available. The carbon keeps your water crystal clear and removes dissolved organics, the phosphate disappears, and best of all, so does the algae. Finally, change your mechanical and chemical media once a month, because as it becomes exhausted and saturated, it may leach the bad stuff back into your aquarium.

Give some Nerite Snails or Amano shrimp a try first. They are the best algae eaters in the freshwater aquariums.
