Hi & Happy Easter. I have a 240 litre tank that’s been going 6 months. I’m running a H2 Ocean phosphate reactor and  protein skimmer. All water parameters are good. However I still get too much hair algae covering my live rock. I have reduced lighting to 6 hours per day. I have 12 snails and an emerald crab. I’m looking to get a foxface..... Any other compatible algae eating fish you would recommend?

Get a sea hare it will soon clear it but not solve the problem completely you probably have phosphate leaching out of your rock. Foxface or a kole tang may help too but will get to big for your tank eventually. Good luck

I'd argue that tank is too small for either fish. Recommended sizes for those fish are 4ft plus. You could get small ones and move them on later.

HOwever, that's addressing the symptoms and not the cause. The cause is most likely high nutrients, even though you're not seeing them in the test results, Algae is consuming it (or it wouldn't be growing) so it's not in the water column to be tested for. Lighting at 6hrs is ok. I'd go with reduced feeding and several large water changes. Also rip out as much as you can by hand. That will reduce the algae's ability to suck up nutrients, reduce the amount of nutrients going in, and reduce anything in the water column that being broken down as waste from feeding, and from dying algae as it rots.

Thank you.... I’ll take another look at what is putting the nutrients into the water. I’m feeding dry flake once per day at an amount that is consumed within 2 mins. Is this too much? I have 4 chromis a cleaner wrasse, 6 hermits , and 12 snails. There are plenty of copepods and aphipods living in the main tank to supplement as a food source too.

Frozen is better than flake, mysis being the best protein to phosphate ratio. Here's a chart to give you an idea of various foods. Overfeeding is the main culprit of high nutrients, but they will build slowly in many tanks, so water changes, and other export methods are used to reduce/erradicate the need for water changes.

Spot on! I was definitely over feeding. Shocked by the amount of detritus in the sand I just stirred up in the water change. I’ll make some corrections in the area of feeding and get myself a chalk goby to keep it turned over. Thank you !!

That's an aiptasia in the middle. You'll want to lift that rock out and dig it out whilst nothing else is on the rock. You should check for more of them, as they spread fast.

Yup I liked it at first as my favourite thing is to patiently watch what appears from the live rock. I’ve just had a couple, and so far they’ve not caused a problem, but as you said they will likely start popping up around the tank so I’ll unfortunately have to remove them.

Red Sea sells Aiptasia X that seems to work well if you can’t take the rock out.

a peppermint shrimp or 2 is a good shout if you want to not go full chemical warfare on those aiptasia.
The fact of the matter is, unless you QT every piece of stock that you buy,  you are likely to get aips come back as often as you nuke them.
A couple of good peps will be fun to watch and will keep you clear of the pest nem's.

That is just from my experience as a non QTing frag swapping junkie ; )

Peppermint shrimps are the only thing that has always worked for me. Highly recommended
