Hi all,

Cycle is finished, the uglies are in.

I've noticed in the morning my water is clear but as the day progresses the mist becomes more apparent.  I did water change 10% last night and turned some of the rocks before I got my livestock today (finally!).  Ammonia and nitrite undetectable. This morning it was clear, when I returned home from shopping the haze made an appearance.

I am assuming I'm getting a bacteria bloom which will pass in time.   Anything  else I can do to accelerate this phase of the cycle (remember I'm a mental health nursing student on budget) without adding any unnecessary expense? 

I do have intense led lighting which is turned down quite a bit (white at 40% max, blue at 60% max and royal blue at 80% max one foot over the tank). I'll ramp it up or lower fixture when needed.  Perhaps this is causing bacterial bloom,  I have noticed the diatoms have been pearling as well.  Maybe raise the light up a bit more? 

Anywho,  it's time for the uglies.  I'm assuming it's a part of the cycle and tank balancing.  I'm not adding any more livestock for a couple months, which will then be corals.   Oh. I may add a few cerith snails in the next few weeks if my current cuc doesn't get to the task of algae decimation. 

Stock:

2x small common clowns
2x spiny astrea snails
2x nassarius nails
2x turbo snails (hopefully trochus, not sure what type though)
6x blue leg & mixed hermit crabs
Xenia frag
Palythoa frag (which was in bad condition when they arrived)
...and the algae lol

So my stocking level is fine.  I doubt I need to worry about the haze.

Input is appreciated!

Many thanks for your wisdom and enlightenment in advance.

Update!

As soon s the lights dimmed it is clear as glass.

Photosynthetic heterotrophic bacteria it is.

Whatever that is lol.

Reef madness...

I don't think it can be both photosynthetic and heterotrophic , have a read of this
Difference between Heterotrophic and Autotrophic Bacteria
As you say you have both algae growth on rocks and either photosynthetic algal or bacterial bloom in the water I'd probably be inclined to test nitrate and Phosphates levels and increase surface agitation to drive of any excess Co2 .

Hi and thanks Gav.

I noticed this is a algae bloom (diatoms?) as I made the stoopid mistake of starting and curing my reef bones in tap water (salt) and didnt wait for my RODI unit to arrive.  I have high phosphates and silicates which are feeding the algae.  Water changes arent helping much so I have invested in a UV steriliser to keep it in check while i run SeaGel and carbon. 

Fish and inverts are fine.  Just ugly to look at.  I did raise my LED fixture up about 6 more inches and hope this will help.  Id do the 3 day blackout but i kinda also want to burn out the phospates and silicates.  the fine coating of diatoms that I am constantly scrubbing off the glass aint fun...  Skimmer is productive though!

Lesson - USE RODI!

Learnt.

Hehehe.   Well, I've removed some  rock out of the display area and broke them up to add to first rear chamber as bio filter.  I've also added a uv external filter (no media besides empty baskets and purigen and seagel- oh a one filter floss pad) to polish water.  I'd have to say that uv is working miracles!  The tank was so cloudy a week ago, now it's visible.  I've added a cleaner shrimp yesterday and won an auction for a bunch of zoa frags.  They aren't that amazing but I got them incredibly cheap.  Skimmer is finally producing wet skimmate and nitrates are low now.  Need some nitrate for my softies apparently. Otherwise I'll add a nitrate reactor, but that seems unnecessary as I'm not aiming  for sps display.  Anywho,  tank is doing better!  Uv zapped the algae or bacterial bloom I had.

Also, a turkey baster is a great investment!  Blast rocks and everything else as detritus into the water column,  and exported in skimmer and external filter (will be removing filter pad at next water change on Friday).
