I'm a bit freaking out reading about Dinos, toxicity, snails dying decaying and boosting nitrates in turn boosting their growth. I was hoping I would only have had Diatoms... will swap carbon and phosphate removing media to fresh ones. Thinking of pulling a trigger on a small media reactor and scrap my canister idea.

Will try to take a good quality pic of this stuff.

take some pictures, upload them. Easy to guess without pictures, easy to guess right with pictures

Few pictures of hairy stuff with a crab & snail in action. I'm in the middle of 25% water change, flushing inlet sponge and replacing media in the canister. I appreciate application of reactors comparing to this hassle... it will never be clean.

That just looks like green hair algae.  Not always very green, but it will be of left.  Low nutrients (nitrate and phosphate in this case) will kill it off.  The cuc  will take care of what's there given time.

You could also help the process along by blowing any detritus off the rocks, soothe slimmer can deal with it. Make sure you have enough flow to stop detritus settling if you find there was much there.

Another water change later, NO3 2ppm, PO4 0. Hairy stuff is not spreading, I haven't cut the lights and maybe the sand is getting a bit brown-ish here and there but nothing major. The rock is getting better and I went for small Aqua Medic multi reactor, cannot be wrong in a 40£ price bracket.

Two tiny clowns (I wanted really little ones) have started eating something, first two days were tough not interested in food at all. Now maybe they don't jump on food but at least eat. Marine pellets and some frozen brine shrimp so far.

The shrimp has molted, first time I saw such thing. It was sitting on the rock looking like a cat cleaning fur and then I had two!

Meanwhile I suffered a power outage which caused Octo HOB1000 skimmer to overflow. Literally it started pumping out the water with ATO topping up... epic mess. ATO now got a timer so it can only work 15mins a day (will pump more that could evaporate but less than in reservoir). I have resurrected an old on-line UPS from my IT days - 270mins of autonomy looks promising.

Learning it hard (wet) way...

Is the skimmer ending up in deeper water when there's a powercut?  That'll be what caused it to overflow.

Nope, it's hang on back unit, when powered down water level in the tank goes up just a little. That alone is not an issue, the startup procedure is. It can overflow when started before flow stabilizes. I was surprised so I put it through a number of tests and as the pump is kicking in water level in the skimmer goes up in the overflow chamber returning to the tank. Not always there's "swirl" formed and it simply overflows via the top.

Interesting developments, since the last water test NO3 dropped to 0, NO2 is still 0, there are some air bubbles in the sand bed but with dKH of 12, pH dropped to 7.6-7.5! Two different tests read sea and tetra (strip) with the same result. I measured at the same time of day Tuesday and it was 8.

Now I cannot boost alkalinity to raise pH nor check levels of CO2. There's water surface movement from skimmer & canister filter (900lph). How to raise it?

Randy is pretty much the reef chemistry god.  Have a read of this:

Very good article and eye opener too! Would have never thought CO2 condensation impacts pH dramatically. Last night I connected air tube to the skimmer and put it out. Today pH is 8.2! This is rented flat so I cannot make any modifications but medical grade soda lime is on its way for DIY CO2 scrubber.

Solving the root cause over addressing effects with chemicals, thanks a lot!

Hairy stuff seems to be in its corner, no diatoms bloom on the sand, just light brown dust here and there.

I cannot work out this QFI dosing , there's absolutely no information what it contains other than add 10ml per 100l twice a week. Bioload may vary so how this rule of thumb work in reality? Will go with Red Sea ABC+ kit.

Also caught a hitchhiker, any help what is that is it good it was removed ? I just spotted a green branch which appeared to have a foot attached to the rock.

There's another one a tiny "white flower" which closes upon touch, so far I was unsuccessful with removing it so will wait until it grows a bit.

Regards,
M

So the things are so far going well, diatoms sit in their corner, hair algae stays put, I have 4 turban snails, 6 nassarious snail, cleaner shrimp, two clowns and a torch coral.

Noticed little ammonia spike to 0.2 and NO2 0.05 after adding more live rock to the tank (was supposed to be cured...) good thing the tank managed to get it to 0 with no intervention. 24hrs later NO2 0, NO3 2. I have read NO3 of 1-2 is the target for mixed reef and not necessarily I have to fight it down to 0 as some level of nutrients are beneficial to corals.

Have also started auto dosing but it is extremely tough to balance things out. Especially Alk and Ca with Ca driving Alk down.  I dose 2ml of Mg (1ml 9am and 1ml 9pm), 6ml of Alk (3ml 10am and 3ml 10pm) and 1ml of Ca (11pm) from Red Sea (A,B,C). Ca is 450, Mg 1440, Alk 9.5 (but is not stable 10.5 to 9.1 swings).
