Sorry to hear about your issue SP.
Me personally, I strongly oppose any external additives/chemicals, to fix a fixable issue.
I agree 100% with ReeferBob. Nuisance algae is usually a 99% water column issue.
1. High Phosphates & Silicates, usually from poor water top off source or tap.
2. Excessive heat can also be a contributor in conjunction with other factors listed here.
3. Excessive feeding which leads food decomposition from uneaten food.
4. Every system will have some algae growth which is normal. Clean up crews are a must to control this.
A combination of crabs, snails and an algae blenny will more than suffice. Pods, slugs, snails, limpets, chitons, crabs, urchins will all help, but all aren't needed.
5. Old/aged bulbs can also be a contributing factor to excessive algae blooms.
6. Check your nitrate levels.
7. If feeding with frozen foods, be sure to thaw first in a cup of tank water, then strain/drain off all the water, then add just enough without over feeding to your tank. This liquid is often nutrient rich and you don't want it in your tank.
8. If you have a protein skimmer, then crank it up as it is the most natural and effective means of nutrient export which is what you need right now. If you think about the frothy foam from the ocean, which is nothing more than what your skimmer is doing, is a natural means of nutrient export. So using the skimmer right now is a must I think and empty the cup daily and clean it with warm water and a dedicated tooth brush. The down side is that you will be removing food for your filter feeding inverts, but there is adequate amounts that you won't starve them and your greater concern I think is knocking down the algae.
9. Though polyps thrive in nutrient rich water, excessive nutrients is the line that's hard not to cross without remaining proactive. If you have any current mechanical filters, they must be cleaned and rinsed frequently as they will also accumulate nutrient rich gunk which will contribute to your problem. Even skimmers should be cleaned including the collection cups to prevent re-entry of what you have removed already. You can try using poly pads/filters, but again, you have to rinse and keep them clean.
10. Carbon is a must, run a high grade granulated activated carbon and only enough based on the size of your tank. It is great in the removal of organics in your system. You can use it in a media bag but be sure to keep the bag cleaned and rinsed. Rinse the bag weekly and discard/replace carbon every 2 or 3 weeks.
11. Using a phosphate removal pad or media will work well also aid in the rememdy. There's much debate over whether to use Ferric hydroxide based or aluminum oxide based pads or media. You will have to decide which is best or maybe someone else can weigh in since I haven't used it in many years.
Hopefully someone else can chime in with more.
