Hello

and welcome

Congrats on the pregs but sorry about the Nitrates.
How often DO you do water changes and how much?
What size tank and how long has it been up and running?
What do you have for filtration?
How much Live Sand and Live Rock?
A young, or over stocked or under "filtered" tank will accumulate Nitrates (NO3) because the system can't "Complete" the Nitrogen Cycle. One of the best ways to remove NO3 is via consistent water changes. Not only does this help remove NO3 it also replenishes depleted trace elements and other essentials that your tank NEEDS for long term health.
The trick here is to determine the reason for your NO3 (Which really isn't THAT high) and tackle that along with the reasons for HA!
Trying to use an "Algae Eater" is a short-term solution but it could also be part of the Long Term solution. HA is from excess nutrients. Either Over Feeding, wrong food, unproperly prepared food or over stocking.
How much livestock is in your tank? How often do you feed? What do you feed with?
That's a LOT of questions but the more we know about your tank the better "equipped" we are to help you get to the resolution.
Hang in there and BE CAREFUL!
