So less food (once every 2 days?)
Is frozen food a tad better at keeping water pollution down? -- generally yes because the fish will eat more frozen food and it is easier to control how much actually goes in the tank. Flake food can float around then sink to the bottom where it is often ignored by most fish. This provides the Cyanobacter with a lovely food source.
Ill probably need more plants too after this so is there an algae buster pack i can buy off ebay/some other store. Dont need too many. -- no idea sorry.
Just checked the gourami and the sore seems to have gone down (got under the blanket with a torch to have a peek xD) -- sounds good
I kinda get how im supposed to beat this algae now
Would an external be a good investment? I WAS going to get a tetratec one but ran outta money xD -- external filters can help by increasing water movement and helping clean up the water faster. However, they won't make any difference if the source of the algae remains. Generally too many of the wrong nurtients in the water and not enough plants to utilise them.
Less light, less food, more carbon for plants, more plants and more waterflow = good
correct?
-- yep, spot on
but leave adding more plants until after the problem is fixed otherwise they will get coated in the stuff.
The other thing that can encourage this is old lighting or lights with the wrong colour spectrum. Lights lose their colour spectrum as they get older and sometimes they drop right down to the red end of the scale. This can encourage the algae to grow. Having lights with a daylight spectrum or slightly higher (6,500Kelvin to 10,000K) can help reduce the problem.
