  • Good and Reliable pump!! By Msobon on 12/25/2013

    My old litermeter finally gave out after 5 years of service, the tubing burst and salt water got into the unit through the bearing shorting the motor and overloading the electronics. Long story short I did not replace the tubing on time and the cause of the break was a nice calcified critter crawling up the tube and cutting it open.

    I've gone through many dosing pumps that have failed, mechanically.
    litermeter is a solid and reliable product!
  • LM3 By Masta on 7/2/2013

    This is on sale now at spectrapure for 269.00
  • reliable By Ryan on 2/15/2013

    I had a a dosing pump go out......lost coral because of alk spike.....then enter lm3....set it and no need to worry again....
  • litermeter By Bob on 6/28/2012

    Was tired of hulling 8 gallon container twice a week from the basement to use for my ATO water, added this pump with 50 feet of line and now just pull my ATO water right from my holding tank in the basement, works great!! Have it set up as always on, and running on my reef keeper with a float switch, and the added Top off module to make sure it never over fills.
  • Flawless By Michael on 2/12/2012

    I use this for ATO. It's set it and forget it. Dial in total amount you want to add to sump each day and it dispenses it in 150 equal portions. No need for float switches, and almost no possibility of inadvertently adding too much KW to sump. And if power goes off, there's no need to reset it. Worth the extra $ for the peace of mind.
  • Great product By Jay on 1/1/2012

    I am using this for automatic water changes from my basement. What a great product, never have to carry heavy buckets up and down stairs for water changes...
  • litermeter III By Matt on 11/10/2011

    Though there are less expensive top-off systems, I wanted something that was reliable, foolproof, and could also pump a great distance/height. My water supply is in the basement, so I simply drilled a small hole to pass the waterline. The system is reliable, and has no float valve to worry about. It is simple, and works great. I have since added a second litermeter and several remote pumps for supplements.
  • Cant get much better than this... By azreefgeek on 4/13/2011

    Great pump system. Using for ATO and Auto water changes. Worth the extra buck...
  • High Quality By Mark on 12/11/2010

    The LMIII is a high quality doser. I use the base unit and another pump for 1% daily automatic saltwater exchanges. I pump fresh saltwater from a 55g barrel through 15 ft of standard 1/4" poly tube into my sump. The second pump pulls old saltwater out of the sump and pushes through 30 ft of tube to my garage utility sink. The LMIII calibration capability ensures equal amounts out and in, keeping specific gravity stable. The small additions don't require temperature adjustments. LMIII is a must for the automated system. Now if they would just make an interface to my Apex controller.
  • RIsk / Reward, you can have your cake as well By ReefKeep on 10/25/2010
