I would like to take a minute to discuss my plans for battling nuisance algae in my aquarium. Out of control algae growth was a contributing factor for the rebuild decision and it is crucial for me to get the upper hand. Here is my game plan for managing nuisance algae in my system, not necessarily in order.
1) Manual Removal: This is how I initially started the process by pulling/tearing/scrubbing as much off as possible. I will continue to manually remove as much as I can during weekly water changes.
2) Water Changes: I have been/will continue to perform weekly 10% water changes using 0 TDS RO/DI source water. During these water changes I blow the detritus of the rock and manually remove what I can.
3) Additional Flow: I am replacing my two old style Koralia 3s with two Koralia 4 Evos (850ghp each to 1400gph each) I will then use at least one of the older units to provide supplemental flow to dead spots.
4) Proper Lighting: I am in the process of replacing the bulbs in my 5 bulb T5 unit. The bulbs are approximately 1 year old and I have already recently replaced one. I will continue to replace the others at about 1 a week. I also use a reduced photoperiod now while I have minimal light demanding organisms.
5) Wet Skimming: I use an ASM G3 with a gate valve mod and it is a pretty effective skimmer. I have been keeping it tuned to skim wet in an effort to remove as many organics as possible.
6) Active GFO: I use a Dual BRS reactor with GFO and carbon. Timely replacement of the exhausted media and correct adjustments will ensure the unit is working effectively.
7) Macro Algae: I have a softball sized clump of Chaetomorpha in my refugium. I plan on trying different bulbs and flow patterns to determine the most effective way to propagate it.
8) Clean Up Crew: I currently have a variety of Nerite, Nassarius and Cerith snails that I hope can help control the spread of additional algae.
9) Dark Period: I may try a monthly 2 or 3 day period of darkness. I have seen many threads recommend this for algae control as well as general coral health.
10) Feedings: Since there is currently no fish in the tank I am introducing no new nutrients via feedings. When I do add fish, I will rinse the food that I can in RO/DI water and feed only what the fish can consume in a short time period.
At this point in time the algae growth for the most part is minimal. Over the course of almost four weeks there has been limited growth in a few select locations, certainly much slower than the wild growth in the previous setup. I hope that with good husbandry habits and by implementing these measures I can turn the tide in my favor and establish a stable, healthy system. Any input on these tactics is greatly appreciated
