Algae Bloom in Tank

[gabriellar]

My tank is one year old. It's been stable until I upgraded my light (previously around 70 par now 150 par with a acclimation duration of 30 days) and then I noticed this algae bloom. A lot of algae growing in the tank like crazy (hair algae, film algae, cyanobacteria...even find bubble algae start to show up with a few, which i don't have before). Along with this, I also noticed my nutrients go down way faster than before.

I'm dosing Nitrate, fusion 1 and fusion 2 on a daily basis now, because per days with no dosing will consume about 1ppm of nitrate and 0.5dkh alkalinity. I'm not sure about my exact phosphate level at the moment, used API test before but that thing has low precision, now waiting on my hanna checker to arrive. I also added macro algae to fight with the micro algae (just added in for 3 days).

Right now, thankfully all the corals still look happy in my tank (mainly LPS and softies), but I don't want to test their limit. I want to ask what is the best way for me to adapt my tank through this period to get back to normal faster.

More info on tank... We got age and some tank parameters.

Size, filtration, flow.

If the only thing that has changed is the light, it could be that your old light was woefully underpowered adn the new light is giving "fuel" to all of this new growth.

A video of the tank, posted to youtube and linked here, would enable more people to try and help.

What clean up crew do you have? To I create chances of getting better help you need to post more info about your system. Pictures also help.

The growing algae - and macro algae - is consuming the nitrate, I would not dose nitrate/phosphate in this case, just me personally.

It sounds like you had your tank in the dark previously and your tank is now maturing with the light. Me personally I would keep nutrients low and stay on course through this phase. Increase the cuc and the water changes in the meantime. IMO. good luck
