5" off the water seems awefully close but I suppose if your not running them at 100% should be ok
Ah, thank you for that reply. I did let it fall a bit, more than I meant to in fact - in about a week it dropped to 8.5. I'm bringing it up slowly. Calcium is down to 375 finally (glad to see its being used!) so I'll mix up the solution and start dosing that tomorrow.
Do you think this drop in Kh could have caused the issue with the coral mentioned above?
Do you like your Radion? Im running a Mitras on my 60 gal cube and it's a pretty high tech fixture and not very user friendly (the interface kinda sucks and it's PC only).
Very nice Greentree, I really like the Red Planet
I have another question. I did the calculation for the amount of 2 part calcium solution to add and it seems like a lot. 6.7 oz to raise 65 gallons from 370ppm to 400ppm? Raising the Kh from 8 to 9 required 1.5 oz. I know these are completely different solutions, but I just want to make sure before I mess something up
I'm going to manually add 1 oz per day until I reach 400ppm, and then watch to see how much the system is utilizing daily. Any and all feedback is much appreciated - thanks again everyone!
