Spied a small nitrite reading tonight (like 0.1mg/l). Less of an issue in marine vs freshwater as salt decreases toxicity and it’s v. low anyway but I will of course now be monitoring closely! No food tomorrow for inhabitants whilst this corrects itself. I have been over feeding the gramma to get some size back into it - although looking online it does seem to me that they all do look a bit like this so I might be worrying about nothing anyway!
Started to see it coming out a bit more with the wavemaker on as shown - have turned off for the night but will leave on tomorrow as I had it today. I thought the flow looked ok anyway for the tank as is... with more corals and grown out macros I might need a bit more but for now I think it’s ok.
Any tips on flow rate given I have a 500l/h pump in the filter compartment of this 60 litre tank anyway? I’m thinking I only need another day 750l/h - 1000l/h from the wavemaker? Also any tips on positioning the wavemaker or can I simply watch a bit of food go round the tank and know all is good?
He does look a bit skinny to me but he's also quite young judging by the size of his eye compared to the body - could just be that I guess. I tried to get a pic of mine for you to compare but it was just a purple blur! Imagine the dipped in bit behind the front fin not being there.
edit- found a pic that looks like mine
Regarding flow, I think it's more important to have it evenly distributed than the exact numbers. A gentle sway on the coral polyps, bit of waving on your macroalgae and no crap collecting in the rocks/sand would be a reasonable place to start.
I found it quite tough in a nano to achieve that without having dead spots or causing a sandstorm!
In terms of numbers the usual recommendation is 20-100x, but that's almost useless to be honest. It really depends on the type of corals, how tightly packed in they are, how the rocks are arrange etc etc.
