This tank was struggling for the last two months, and after finding a couple minor things (bad calibration solution which made me think 31ppt salt was 35 was the biggest), I honestly think that a renewed focus on stability was the biggest factor in turning things around.

In the last couple weeks my system really seems to recovering fast. Coral growth has taken off again, corals are encrusting, I'm getting growth tips back, and the rate of consumption of Alk and CA has gone through the roof. Prior to the tank starting to struggle it used 80 ML of Alk per day to stay at 8 DKH, then it went down to 40 while the corals were dying and doing badly. Now I'm up to 120 ML per day! And growth is faster than ever before, I'm also seeing better pylop extension so I take all these things as awesome signs.

Now for some updated pictures:

Thanks Doug! The Video you are referring to, is that the one in my signature?

Thank you,

Hello all!
So I was in Huntsville Alabama the week before last on a five day work trip, and as it always does, my tank chose that time to have a pretty serious issue. I have been using a BRS 50 ML/min peristaltic pump for my auto top-off because it was $79 and the Spectrapure Liter Meter is $279.

When I came home from the trip I found my sump nearly empty and the pump rotor was not spinning, I figured it was the Apex so I plugged it directly into the wall, and it still wasn't working, so I took the cover off and moved it manually and it caught and moved a quarter turn and stopped. I took the pump apart and the gearbox had completely worn out. There was this grease soaked plastic shavings all over the sides of the gearbox and the gears looked like they were filed down.

Here it is after I cleaned out all the grease so I could get photos:

I had an optical level sensor from Apex in the sump, but it was attached in a way that it's difficult to clean or inspect and as a result when I finally needed it the sensor was covered in Coraline and failed to sense the low water level. I didn't know that was an issue, but it is.

To make sure I get alerted in the future I made this. It is 2 Optical sensors, and 2 float sensors. This part is just for overfull/underfull, the topoff trigger itself is the Avast pressure one.

As far as the BRS pump goes, this is obviously 'normal' wear and not a defect of some kind. The plastic they use on those gears has a shorter lifespan than the tube in the pump which is unusual. I have replaced the one on my big system with a Kamoer pump used for industrial stuff off Amazon. There just isn't a reasonable option for the hobby. This one is rated for a life of 1000h on the tubing alone so it should last 6 years before any maintainance is needed at all.

It never fail , things pick the worst time to fall.
First up......HEY WHISKEY! Great hearing from Ya!
Second......WOW...THAT sucks!
Hack
Sorry guys! In my head I replied to you. Yeah, the worst time to fail,.. and such a bad design. The good news is that I now have like 10x redundancy on this system now. I have the dual sensors for alerting, then I have the new Topoff pump which is much better, then I have the Kalk on it's own pump which handles 90% of the topoff needs by itself. If the topoff pump fails again the tank could easily run on just the Kalk pump for a week. If Kalk fails, I could adjust 2 part to make up the difference for CA/ALK and make it by.
