I know common issue. I’m not having any luck hoping for some special advice for my situation. lol.

I have a 112 gallon reef (143 total). Started with dry rock about 18 months ago. I avoided the ugly phase leveraging my experience from reefing 25 years ago before returning to reefing and via reminding me of things I forgot or never knew back then on these forums.

Well about 3 months ago I started to get some hair algae and it’s only getting worse, now to the point that it’s starting to bother corals. I never had an issue until I decided see if I could further my lack of experience with SPS acroporas that kept dying. I tried using Aquaforest LifeSource and boom I all of a sudden has hair algae appearing. I’m not sure if the Fiji mud introduced something bad I didn’t have (bad comes with the good) or if just coincidental but the timing is what it is.

I’ve never had a Nitrate issue in this tank. Have always had to dose Nitrates. I had to dose phosphate for the first year before the dry rock was saturated I guess and the last say 9 months been using phosguard and a bit of phosbond in a filter bag - high flow area in the sump which does help with phosphates but doesn’t last long. I’ve recently implemented Lanthium for long term maintenance (started maybe three weeks ago). When dosed by hand into my reef Matt it clearly had a reducing affect so last week I went ahead and rigged a doser and am dosing directly into the body of my skimmer. I’ll observe its affect was much better when applied to the reef mat as a single dose vs the skimmer body over the course of the day but I digress.

My phosphates are currently around .09-.13 I’m dosing 4ml of Phosphate-E over the course of the day. Tank is Seeming to want to stay around .12. Still adjusting the Lanthium - don’t want to get too aggressive at once. A tad troubled that 2- 3.5ml in the reefmat was more effective then 4ml into the skimmer body…., Before starting Lanthium and using the PhosGuard. I’d usually run between .07 to at times close to .2 before pulling it right back down by replacing the media. I was never great timing wise to replace media but generally phos had not been a significant concern and I still don’t see as being all that high. I don’t want to be bothered with a reactor and GFO - too much troubles to maintain. My Nitrates last were 9.9, I have to dose daily to have measurable nitrates and i try to keep above 5 and have had to do so long before the hair algae appeared. I don’t seem to be having to dose more since the hair algae appeared. I want to get the phos back to around .07-.1 and nitrates to around 5-10 goal wise

About a 4-6 weeks ago I restocked some of my clean up crew. Adding like 7 mexican turbos and 70 astreas. I also got an algae blenny but rarely see it. I don’t really like hermits as snails need replacements any without crabs. I prefer trochus but they are seemingly out of season and quite expensive right now so my population is down to 15-20 of those.

If I don’t get a handle on soon I’m headed to chemical methods that I may regret based on some reading so looking for advice first. I’m thinking of getting a sea hare - never had one before. I’m researching chemicals such a fluconazone and Razor hoping you all can either allay my fears, talk me out of it or make me feel better and find a path out of this stuff. I don’t recall ever having to any extent back in the day and my tank back the was much dirtier but it’s been a long time so this is new to me :-).

sorry for long rant

~ 1.5 cubes of mysis and some pellets morning and evening. I just got a plank feeder as the Ehiem failed on my smaller tank so I decided to splurge. Pellets was less than 1/8 of a teaspoon (for the day) with the Eheim when I tried measuring to adjust the plank to similar. The plank is much less consistent, not all that happy with that, but the fish seem to enjoy it. Using a mix of their reef jerky and the pellets I was using before and likely feeding less at this point as I don’t trust the plank as yet. Generally the tangs get 1/4 sheet of Nori in an Aquagadget feeder so there is little waste.

Add. Pellets are a mix of small TDO, new life spectrum and seaweed extreme. For all my fish I don’t feel like I feed all that much at least when I compare to other fish posters :-)

For me it wasn't nutrients. I pulled my chaetto and dosed the FluxRX. I had the outbreak twice. The second time i had the outbreak i treated twice. No issues since and its been months. As a long shot i would say feed less food more often. I use the 2 fishes frozen food feeder. It lets the food melt and distribute slower. I think less of it gets pasts the fish and into the sand that way. Flakes and pellets are dense concentrated foods. If they get past the fish i think they can feed the flames. I tried everything else before i dosed it but sometimes algae just gets a hold. I use flux as a last resort.

Thx. I’m cutting back on feeding and got the plank to do more micro feeding vs larger feedings so with you there. Im still working on bringing the Phos down a bit more and probably lighting schedule for a bit.

If I get there, not there yet only researching incase other measures continue to fail, how well did the flux work? They say on the I instructions that not good for hair but I hear mixed reviews as to effectiveness that way. Did the doses you give hurt any corals etc?

I really wouldn't worry about your lighting schedule as this will adversely affect your corals.
I'd focus on decreasing feedings first.

A cube and half of mysis twice a day plus dry food for...I see 6 fish in the photo...is quite a bit. I do notice anthias which need frequent small feedings to keep them healthy. This could mean a few pellets each. I have feeling you are battling high nutrients and GHA due to feeding.

Long list of fish. 3 tangs - two good sized ones, 4 Anthias, coral beauty dwarf Angel, mated clown pair, blue devil, watchman goby pair, jewel damsel, mated Mandrian pair, Dottie back, algae blenny and probably some others I’m forgetting so around 20 or more. Eg maybe too many fish…. I know I’m done adding for now. I have two in the other tank waiting to move in but concerned the residents will take them out so growing them out a bit and wanting to get control of this mess

Definitely will try a bit less food but concerned going too far. I don’t consider myself a heavy feeder but maybe I am and that’s why I’m here :-). Some seem to say cut back on the tangs Nori (1/4) sheet a day to try to make hungry and more willing to eat the algae and will try that.

That's a lot of fish for a 112. What's the dimensions? 48x24x20?

That's a huge fish load for that size tank. What tangs are in there?

A scopas (oldest of the bunch but a runt). A Red Sea sail fin that is 5-6” so medium and likely reason the scopas is a runt as he is the king and a powder blue that is 4” or so and willing to put the sail fin in its place. They are not real big but as get bigger the sail fin or the powder may need rehoming. No new fish have been added in oh 9 months save the pair of watchman’s.

Knock on wood. Six months of yuck….. 95% of the hair algae is gone. I hope it does not come back.

Goni’s were closed up for at least four months. They have been open the last few week now. Goni’s lost most of their color, but have gotten much of that back now that they are regularly open. I did loose my two clams, one I let get overrun by Zoas but also running nutrients lower then I would usual. Mostly my bad for being discouraged and not addressing things like the Zoas. Everything else is doing well.

Needs some housekeeping now as there is hardly any room left anywhere :-).

My nitrates are stable around 10-12 now and I’m not having to add neonitro. Lanthium is pretty much figured out and trying to keep around .06

Thanks everyone for their input / help along the way.
