Now for a conitnued tour of the basement set up. But first a few full display tank shots for fun.
This is the 89 gallon, the newest tank
On to the basement
Full length shot, best I can get
This is the litermeter 3 which I use as a dosing pump for limewater as top off. I fill the rubbermaid can with water from the ro/di water barrel manually every 5 to 7 days,add kalk powder and stir with a length of pvc pipe. The liter meter provides a set amount of this mixture to the display in little squirts spread over a 24 hour period. If I choose to just dose the kalk at night I can easily employ a timer and adjust the dosing amount.
Incidentally, there is no need to stir more frequently. Limewater in a covered still resevoir will retain it's strength for well over a week
On the other end of the system I employ a calcium reactor for additonal calcium and alkalinity.
Both the dissolved calcium carbonate and the calcium hydroxide from the limewater resevoir are balanced in the proper proprtions in terms of alkalinity and calcium.I never need to use calcium chloride and buffer anymore but could if I needed to tune it up some.
The calcium reactor effluent has a ph of 6.7 and contains CO2. The llimewater has a ph of 12.4 and takes up CO2. Using the 2 together I am able to maintain ph at a morning low of 8.28 and an evening high of 8.38. Akalinity is a steady 11.2 with about 520ppm calcium.
