TLDR warning!!
To answer I have a RR 650 (180g), RR 450(110g), RR 300G2 (80g) & 170 (45g) …. little/no sump space either..
650 will be SPS,
450 (Atlantic/Gulf, Gorgonians, Rock flowers, zoas, et)
300: Clams, LPS
170: Torches, hammers, alveapora , blah blah
…I broke it down like that to simplify flow and alk consumption, so I’m looking for a holy grail solution of cost & simplicty that doesn’t involve expensive 4pt dosers, dosing and ordering from BRS every month, basically something involving 2 dose heads and no commitment to weekly H2O changes…Also relevant is living in SC with summer 90’s, AC, closed windows, high CO2 and low pH issues…
I am a old school Kalkwasser user but don’t have the space for volumes of storage so I’m currently researching Stirrers, but nobody’s reviews have given me confidence to pick a brand/model ..
AFR seemed as attractive option up and until I depleted that $80 can and I’m thinking of somehow offsetting the consumption with Kalk and its pH boost as a side benefit…
Randys newer high pH 2pt formula is also in consideration but that sounds like it needs support with a trace solution or maybe more water changes, which I can’t support w/o a RO unit (for now I’m using carbon filters rain water for top off )
This input is giving me confidence to maybe pursue using Kalk with AFR to maybe offset some of that cost… I lost most of my stock moving so its also a wait and see approach …
……….. TRUNCATED QUOTE…….
Rough math:
$75 TM AFR 1600 g
1600 g makes 10 liters
10 liters = 10,000 milliliters
10000 / 110 = 90 days
$0.83 per day
$300 per year in TM AFR 1600g powder
Numbers more or less seemed correct. Single dosing head and a product what I believe is covering the majority of Ca, Alk, trace elements, and Mg. Using these numbers I decided to stay with TM AFR. I still have ESV 2 part to manually bump if needed and it does happen from time to time. The spare dosing head (I use Neptune DOS) is free and I've been using it for ESV's Transition Elements. I may move it over to LC though - not sure.
Kalk or one of RHF's blends may be cheaper and yield a ph buff and has a sound history behind it. In any case the wall of text above is my reason for using TM AFR. Early morning photo of my display as I work on cleaning the glass and blowing off the light fans.
Note: also know I don't point my success, or luck, to any one product be it lighting, or what I dose. I believe I would have the same display if I used kalk or a 2 or 3 part. I think that is important to clarify. I use TM AFR for ease of use and what I believe it brings to the table in a single product.
