So, I've just recently had my new tank up and running (50G + Sump), it's been about 3 or so weeks of actually being up and running (did a majority water change when moving the LR around before the critters went in), and probably about 1 week or so worth of actually having critters in it (Initially 2 fish and a shrimp, then 2 fish, and then now another fish and another shrimp (3 fish, 1 shrimp, and 6 pieces of coral). I've just started to have a diatom bloom, and have noticed a little bit of green hair algae.

I'd like some info on experience from the masses before I go by what I've read to try and manage this as best as I can.

Info on my system:

I've around 100 LBS of LS, and about 100 LBS of LR (which both came from an established tank).

My CUC is currently :
~ 12 Nassarius Vibex
~ 15 Dwarf Cerith
~ 10 Florida Cerith
~ 12 Nerite Snails (Small - Medium)

I'm running 5 Red Mangroves (small) and a tennis ball worth of Chaeto (which has grown a little in the last week or so) in my sump, which is lit by a clip on with a 75 W Plant Light (but will be moving to a stronger light tomorrow).

My levels are all at the levels I'd hope to see (0 - Nitrate, 0 - Nitrite, 8.4 - PH, 0 - Ammonia (can't recall which test of the two I did, free or total, but it was 0, which ever one it was), 1.023 <-> 1.024 - Salinity (depending on day, and last top off)). Nitrates did spike a week or so ago slightly (ever so slightly, was just registering on my seachem kit), and salinity did drop last week to 1.021(ish).

I've been using R/O water from Walmart / H.E.B, until I get to the point that I'm going to buy myself a RODI system (which will probably be in a few weeks, but wanted to rather spend the money on something other than that in the meanwhile).

I've T5 Lighting (Pennies2Cents old system) running for around 12 hours a day (10 white + blue, 2 blue), with a 300 GPH from the sump to the tank, a Coralife 220 Skimmer, ChemiPure Elite (medium sized bag) and then 1 powerhead currently (will be getting 2x 750GPH in a few days from Marine Depot).

I'm about to do my first water change (the weekend coming) and am plotting a 15% change. I've been feeding emerald cuisine since I added the critters (initially one block, then 2 days later 1/2 a block, a day later 1/2 a block, and then 2 days later 1/2 a block, etc... day break between blocks, and 1/2 a block per day over 2 days). I've spot fed corals once with Coral Frenzy (post bloom).

Outside of that, I've been dosing the E.S.V 2 part for about a week now, the coraline seems to be 'popping' which looks better at least ;) and for the last day or so I've been adding magnesium, and will be testing for it tomorrow onwards.

So what do you guys suggest I do to assist managing the bloom / tiny bit of hair algae? Here's my plan, please feel free to tell me what else to do ;)

* - 10% water changes every 5 days (30% over 2 weeks)
* - Increase flow in tank (as of Monday)
* - Add some more snails, possibly turbo's for the meanwhile (as I've not got much they could push over, my frags will be moving into a frag rack shortly, thus there's nothing for them to really push around)

So, ideas?
