Tank is doing well. No concerns. Will update a full shot photo in the next day or two.
Near Zero water change:
Approx. 18 months ( Mar 2015 ) since going on the near zero water change. Sump is getting pretty nasty and there is no good way to clean it without dumping water so I do plan a 40g water change later today to completely drain and refill the sump. Tank parameters look just fine, the only reason for it is to drain the water via shop vac ( since can't siphon is out ). This is where the near zero water change comes into play as I knew an occasional would be require to clean the sump.
.055ppm Phosphate using Hanna HI736 Checker
7dkh Alkalinity using Salifert.
Summer Tank temp is staying at 79 - 79.1

I'm low on my HW Trace Tip-1, HW Trace Tip-2, HW Mira-tip trace element supplements. All 3 run about $60 and lasts me 2.5 months.
Before Fall comes I need to replace my UPS Marine Battery costs around $80.
Undecided which direction to go with replacment dosing pump for Kalkwasser so that may be an upcoming expense. Either replace the head unit $90 or just continue with the aqualifter.
No other known expenses for the coming month.
Turf Scrubber Status:
I did replace and reseed the screen about 3 weeks ago. About every 6-8 months the screen starts to get ripped from the weight of the algae etc. I am a bit concerned as reseeding hasn't bounced back as well as I had hoped. Normally withing 2 weeks its back to full thick green but has more of the brown slime on it than I would like to see. No adverse reactions from the tank itself so I just leave it be for now.
Dosing Pump Status:
Replacing the Tubing in the Spectrapure pump did not resolve it. Will need a replacement head. Unsure which direction I will go. The Aqualifter seems to be doing adequate job when used in conjuction with Apex at 10 seconds on , 5 Minutes off during the lights off period. I may just stick with the aqualifter since it's cheap and readily available for replacements.
