Well, took apart the hood and gave it a good old clean. There was a good buildup of salt and dust in there!!
The fans do seem a bit quieter, but still noisier than they should be. Will just get a couple of new ones I suppose. However a lot of the ones I see on the internet have 3 pin connectors (eg: 3 wires), but my Orca ones only have 2 - so might take a bit of messing about to get them fitted ok.
Tank parameters remain the same for the past 2 days
Nitrates: 5
Nitrites 0.1
Ammonia: < 0.25
However I have noticed that my temp is higher then it was before the crash, it is now just under 28C, and even lowering the heater temp dial hasn't made much of a difference. Will probably be getting a new heater anyway, so that might help.
I thought my Halloween crab had died last night, but it was the old "Haha, I've only shed" trick, thankfully. My astraea snail seems to have taken a liking to it though, it is constantly hitching a ride on it's back! lol
My clove polyps (of whatever they are lol!) have really took off in the new setup, they look great! I would love to get some green star polyps, anyone have any info/experiences with them?
