mY wAtEr PaRaMeTeRs

I recently bought a bunch of salifert test kits and tested my water to see how everything was looking, wanted to post my findings... I have a 90 gallon with 9 fish that this sunday will be 13 weeks old. I use water from a 60 gpd spectra pure ro unit mixed with tropic marin reef pro salt and run a phosban reactor 150 and a euro reef rs 135 skimmer. Here are my params:

alk = 2.74
magnesium = (did 2 tests to make sure) 1140 & 1230 figure 1200
calcium 390
phosphate = 0
nitrate = 0
ph = 8.0 (test was done at 2am) think i read ph is slightly lower at nite? maybe wrong...dunno

Im wondering if i should start increasing my mag and calcium? i got bionic 2 part for calcium and alk and dt's magnesium. Suggestions for target levels?

Btw, fish & corals are happy

Thanks
Dennis

 

Start with Mag first(1400-1500), then Watch to see which of the two is lowest(Cal or Alk) and start dosing SLOWLY. I keep my Numbers as follows;
Mag--1400-1500..........Cal--400-460.........Dkh/Alk--10-14/3.54--5.03.........temp--77-79..........SG--1.023--1.025 Keep us posted. Luna

 

Your pH level will be lower at night due to photosynthesis subsiding, first of all.
It depends on what and how much of a bioload you have. Also, if it isn't broke, don't fix it comes into play!!!!

 

Ditto on above.

Ca is fine unless keeping numerous sps corals.

Let regular water changes manage your water params for you. Using additives usually results in "chasing your tail" all the time to keep params in sync.

Good luck.
