Nice job mate! It's really coming together.  Cabinet looks awesome as well, really neat!

Ok, slightly annoying ATO system. If I slow down the return pump, the water in the sump rises and triggers the float switch and sets of the alarm. I then have to turn the ATO off and back on for it to function again. Here's the catch... when it's turned back on, if the water level is already where it should be the ATO pumps water in anyway until it triggers the float switch again. It seems to only recognise the water level if it raises UP to the required amount.

So when feeding, I now turn powerheads off, keep the return pump running normally and then the problem is avoided. Not ideal as some food probably ends up in my sock.

It's running very smoothly, though. The pump for the ATO also fits (JUST ABOUT) in one of my jerry cans, so I have a 25L reservoir. If I'm not mistaken, that will fill my sump almost to the brim, so there shouldn't be any leaking... however my salinity would take a bit of a hit.

News of the day.... the interior exterior tap is fitted in the utility cupboard next to the tank. I plan to get a 5m length of tubing and have the RODI unit running near the bath in case of overflows. I was going to get a float valve and have it run next to the tank but I would need one that turns off the booster pump too, so I'll leave that for a later date. As of this weekend, I won't need to drive 20 mins away to buy RO water!

you tank looks fantastic, i might have to invest in one of those algae reactors, it looks ideal for our new tank to keep the nitrates under control.  May i ask what the monitoring software you have is that give you the readouts?

Many thanks

Ahh man. An aiptasia has grabbed my 1 inch hermit crab and eaten it. Nigel was my wife's favourite critter. It's shell was slightly too big and he was useless at walking around so I guess it was bound to happen eventually. Shame he didn't move into one of the other shells I've put in there.

Also, can't find my emerald crab that was added about 2 week ago. Not seen the shell but I'm fearing the worst.

Gloomy day

Time for an update...

Nigel (the hermit) is alive. He must have molted and hid so deep in his shell that we couldn't see him. Wife and I are very happy about that.

A snail died and I pulled him out. Did the sniff test. Regretted that massively (a week later I could still sort of smell it). Put it in boiling water and then soaked in citric acid for a couple of days. Rinsed thoroughly and popped it back in the tank. Ready for Nigel should he wish to move home.

I've noticed that as the water quality improved, the scallop hid away more, despite dosing some zoo/phyto for it. When I picked it up, it poured out of the shell. I didn't do a sniff test on that.

Scooter blennies and tangs are enjoying the sand bed. It's currently in the ugly phase but the bare bottom looked worse so I can't complain. Need some extra sand for the back part of the tank.

The weir comb was botched together with double sided tape and tie wraps. It wasn't on the list of things to get sorted immediately so it's been like that a while. Today I sorted it out. Runs quieter, looks nicer and looks like I've actually put some effort in Still need to sort the corners out though. Currently tie wrapped but I intend to fix that.

Big Blue (the regal tang) has a habit of flicking water out of the tank to get my attention after feeding time, or when I'm messing around in the sump. Anyone else's do this?

Also finding it strange that the DI filter only has an inch of water at the bottom. I suppose the incoming water pushes the water at the bottom up through the resin chamber so it's fine.

Just re-read this, you probably need to open the DI container a few threads until it fills up with water then retighten it. That will get rid of the air lock.  Vyair will be able to advise.
