aahh man, no snail deal for me
its all good though, the bloom is gone
Both probes have recalibrated and read within .01 of each other (7.00 and 7.01 in the calibration solution after recalibrating). For the tank probe I used 7.0 and 10.0 calibration solutions; the chamber probe 4.0 and 7.0 solutions.
perfect.....
pH in the sump is currently 7.96. I expected higher than this, but this is fine since the alk is sooo high right now.
that is about what i expected, chemistry wise those last numbers are about the same as mine..
With the pH probe in the chamber, I dont need to adjust both the BPM and the effuent flow rate, do I...as long as the solenoid isn't constantly turning on or off and I have a pH reading about 6.55? Anyway, I've been adjusting both. I think I need to slow the effluent flow rate and leave the BPM alone to reduce the amout of alk released into the tank? Is that right?
yeah you dont need to adjust the BPM, you might want to so your solenoid dosent go on and off all the time. also if the BPM is too much when the solenoid dose come on it will flow too fast and end up collecting a "air pocket" at the top in the chamber..might not just something to watch.....its not bad persay if you vent it out from time to time...
i dont think you need to adjust the effluent rate any, your Ca+ is being maintained at 405ppm with you current settings. give it a couple days at the current effluent flow rate. you may want to reduce the BPM (CO2) for reasons above but thats it. for now i would just leave reactor where it is(reduce BPM on the CO2, just cause) otherwise your good on the reactor for now. let the alk come down on its own or better yet keep it there, you are correct on the alk level, its perfectly fine with your ph. with your current alk even if your ph goes up its all good, that is unless your ph goes into the 8.5 ranges. but right now your alk is compensating for the ph, if you reduce alk to 3.0meq/l or lower its likely your ph will start to swing and dip too low at night again. i was only reducing mine because i was thinking the ph was going to go up with dosing balance, prior too i was keeping my alk at 3.5 but i think its better at 3.8ish (a little higher than your current level) for ph stablility...
of note; i did my normal routine water change last night and oopppsss'd my dosing of the new batch..i dosed some reef builder(not buffer
) thinking it was Ca+(i use RC salt and need to add Ca+). so the new batch's alk tested in at 4.92, i did the water change and that brought my alk in the tank to 4.0meq/l...current readings..
Ca+ 420
Mg+ 1350
alk 4.0meq/l (200ppm)
ph- 7.98-8.08 (this is high/low through out the day and night after the water change)
i will let the alk come down to 3.8ish and keep it there. if needed will lower it during the summer if the ph starts to drift upwards. if i see ph climbing and maintains a ph range of 8.2-8.3ish then i will decrease the alk to 3.0ish.
