Default New Tank algal Bloom

Hi all,

Ive never posted anything on a forum so please excuse me if I make a fumble or two.

MY Tank:
20 gallons dimensions (450mm(w)*340mm(d)*400mm(h))ish
Aqauclear 301(new 30?)
4 24w t5 (2*day, 2*actintic)
co2- 1 b/2s
substrate planted fluval
Water parameters not sure yet.

OK, Ive just set up my first planted tank from a marine system (hence the overkill of the lights). Did a degree in aquaculture, thought the process of FW plants would be easier than SW corals (reason for the self deprecating name)

Been cycling for about 2 weeks with the aquaclear seeded from running on another cycled tank for 4 weeks.

Put plants in 5 days ago (HC, Hair grass, Banana lilly, Java moss).

4 days ago, white cloudiness (bacteria thinks I).
3 days ago, green water (unicellular algae bloom I think), slowly getting thicker.

My questions are:
a) I assume that the algal bloom is due to excess nutrients, light or co2. I am curious as I am not 'dosing'; will the resident bloom eventually die out as nitrogenous compounds are sucked out of the water column?
I ask this only because I have never worked with a system that has a nutritious substrate (the fluval)?
Will it continually add nutrients to the water column? or will it eventually decrease and give the benthic plants a chance to establish?

b) I am not worried overly much about the radioactive glow coming from my tank, but will an algal bloom prevent the other plants in the system from photosynthesizing and therefore killing them eventually?

As with my experience with recirculating saltwater setups I planned to let the algae 'run its course'(until all of the nutrients is used up). However, with the fluval as a substrate I am not sure whether it causes nutrients to diffuse into the water column?

But for the sake of the plants I am curious if I should to a water change so as to give the other plants to establish themselves.

Any assistance would be mega appreciated and also apologies for the plethora of spelling errors.

Cheers
