Help with tank

[Paul28]

ummm your ph in the reactor is 7.5 ? or your have it shut off when your tank is at 7.5 ?

Yeah I was wrong, lol. I went back to double check.

I think he has an internal probe.

if you have the internal prob to shut off the co2 at 7.5 its not melting anything its just pumping strait co2 into your tank :(

+1, it needs to be alot lower like 6.6-6.8, what media do you use w/ the GEO ? small or large?

I don’t know much about calcium reactors except to say that tank crashes have occurred from improper CO2 adjustments and / or pH probe calibration inaccuracies.

Chemi Clean has cause many tank crashes. People have used Chemi Clean and not had a crash, others have had a tank crash (or many tank crashes) and do not blame the chemicals they dump in their tanks, but they still wonder why their corals died.

Simply put, if it kills the cyano, what other biological life forms is it killing.

Aside from the possible CO2 issue, chemicals often destroy the lower biological trophic levels that we have learned to establish in order to successfully keep corals alive in captivity for extended periods.

We should dose elements, not chemicals in order to maintain an ionic balance and a biologically sound closed captive system.

also what is the size of the reactor becuse omg your effected drip is high and the co2 is way way high

I have the Geo 612 and it recommends coarse media. The holes on the bottom are too big for the fine media. I have the internal ph probe and the instructions that came with it said 7.5 I will lower it to 6.8. Should I try to lower slowly and reduce it by .1 or .2 every day or just go ahead and change it to 6.8?

i'd go straight to 6.8 , let it run for about an hour and then check the effleunt drip.

Check for what? This is my first calcium reactor. What should my alk/calcium/mag coming out of it?
