Hair Algae Vs Bryopsis = Final update

OK.....I will keep raising my mag. this week and tell you how its going.

 

I hate to see this in your tank unnecessarily...Mg boosting is a slow journey for this kind of invader

Your tank would be easy to treat, the 300 gallon ones were the real problem tanks

If you want it gone be sure and read all the linked threads I posted, all answers and pics are there. A 46 is easy!

 

Well....I must be blind because I don't see it.

 

Your tank is ideal for the external treatment method in the thread

Your corals are on rocks that can be lifted out, its worth the work of restacking

Plus you can clean out detritus underneath them

Once cleaned you won't have to strip down the structure
This is just the price of not taking universal action

Lift out a test rock

Apply 3% peroxide from a new bottle, unopened

Dropper it on the target, not touching corals.the tufts will wick in the peroxide, use paper towel dabs to keep it off corals

Let sit two mins out of tank, treating

Rinse in clean saltwater, reinstall, take pics in 4 days post back just a test rock
You will think its neat. Will solve your prob. Might need one follow up run, this is dense with strong holdfasts

 

Tech M mg up to 2100 ppm didn't kill mine, but a sea hare is working wonders!

 

Mag is at 1800 now and I am starting to see some results. I have been a little scared to try the peroxide thing but might give it a shot today. I have a tuxedo urchin on order and hopefully that will help a little bit. More pics to come this week.

 

Ohh.... btw here is my set up. 46G bow front approx 6 years running. Metal halide lighting 2x250w using these bulbs I bought in January 10000K Metal Halide Bulb - Aqualine AB, Double Ended. Running lights on 12 hours per day.
Filtration is wet/dry with bio balls 300 gph. Rena Filstar XP2 canister 300gph. Aquaclear 70 power filter 300gph. Coralife 65G super skimmer.
Circulation is 2X Pico Evo mag pumps 300gph with rotating deflectors. One Koralia evolution 750.

 

That's great info

12 hours metal halide, full on?, is 3 to 4 hours longer than I run mine
I'm surprised the algae is contained like that
Do you have a ramp up/down period for the lights

 

Halides are on from 12pm to 12am. The fixture has 18 moon leds (9 white and 9 blue).
Blue Leds are on from 8am to 12pm and then again from midnight to 4am
While Leds run from 11am to 12pm and then again from midnight to 1am.

So I kinda have a ramp up/down period but its not good.

I also realize the 12 hours light cycle on is too much but I am ADDICTED to looking at my tank under full lighting. Someone please post here how bad that is so I might get convinced to turn the lights back to fewer hours.

 

If your corals aren't visibly suffering from the last 6 years of lighting why change it. You already said you like it where it is =).
