This is my take on chemicals, because I have been desperate enough to use these sorts of things.
1) Your tank is young. Give it some time and see what happens. Such blooms are pretty normal. Just follow some of the advice that is given on it to make sure your tank is running up to speed.
2) If/when, in a mature tank, you have an issue that becomes so overwhelming that you really have no idea where to turn and are at your wits end, then I would do it, and I have. Because no, it doesn't solve the problem, but it alleviates a problem so that you are not so overwhelmed and can get back into the maintenance and enjoying your tank. If you enjoy it, then you can start solving the problems and maybe start spending money on it. BUT, these things can go wrong, you stand a chance of potentially losing stuff. People report that now and then. I was always on the lighter side with dosing. But I can see where problems become so overwhelming that it is a last resort to save interest in the hobby.
At this point, I would say your tank is still young, there are a lot of nutrients in young tanks that are fluctuating a lot. So I would give it some time to mature before taking what I would consider to be a last ditch effort.
