Looking for feedback here... I am having a hard time keeping Alk consistently up. I am targeting 9.0 I am at 7.6 -7.7 Alk after a 20-25% water change with Reef Crystals and 400 CA. Ph is rock steady at 8.3
My setup: 120 mixed reef (Soft, LPS, SPS, Zoa) SCA display, 55 basement sump. Protein skimmer 7x24, carbon 7x24, phosban 7x24
Dosing:
ALK: 7ml 24 times a day of BRS Soda Ash, raised that to 8ml 24 times a day this AM. (I have had a mixing problem with RODI for months until I got help and started heating the RODI water before mixing, the net resultI was dosing somewhat weak solution. Dosing CA 15ml)
CA: 25ml 8 times a day
RODI: 75ml 24 times a day on two heads so 150ml 24 times a day (I supplement this with an DIY ATO that does maybe another 5 gallons a week. (Open top DT, Open top basement sump with lots of suface area/flow and a low velocity fuge). I draw each RODI dosing head out of its own 5 gallon carboy
I just did a test mix up of Kalkwasswer 1 Tablespoon/5 gallons it is clearing with no precipitation. I plan to leave it for a week and see if it does.
I am thinking of using the 1 TB/5 gallons on one of the RODI dosing heads to maintain levels or maybe even back off a bit on the 2 part. I am concerned without an Apex (not buying one at this point) to shut it down if the PH spikes. Thoughts?
