I currently have a 500w heater in there but only 1, not 2. So maybe I misunderstood.If you were aiming for 300w of heater power, I would aim for 2x 200w heaters instead of 150’s.
For 125 Gallons I believe that they were recommending instead 2 200w or 2 300w heaters. It is better to half your desired wattage and split between two heaters for redundancy and safety factors. Larger systems might even run three heaters or more.I currently have a 500w heater in there but only 1, not 2. So maybe I misunderstood.
Thanks for your reply to my question. I am particularly interested in #2 on this list. I’m not far enough in for #3.I can confirm; the majority of tank issues in decreasing quantity are related to:
1) Temp (everybody)
2) Salinity (primarily affecting new reefers)
3) Alk (primarily affecting moderately experienced reefers)
Newbie mistakes : Not checking salinity before water change to match and matching temperature so the salinity is true match. Not using their ATO properly or one at all also causing salinity issues. And changing salt mixes and forgoing stability too many timesThanks for your reply to my question. I am particularly interested in #2 on this list. I’m not far enough in for #3.
What do you think the biggest mistake new reefers make with salinity?
Thank you Shari. I may take you up on borrowing the Hanna since I have some Dr appts coming up over there. I will call Neptune to see if they can help me. I know these probes can be touchy and need to be cleaned regularly. I just question the accuracy because I didn’t use the Apex probe with my QT’s and had no problems with pH according to the test kit. Thanks AGAIN for all of your guidance and support.The most important reading that APEX can give you is a stable reading that is consistent- although it might be slightly not perfect. But, the probes can be really off and you can ask Neptune - put in a service ticket and reach out to them - to see if they can help. You might have to have them replace the probe if it is not reading or calibrating properly, or they might give you some help with the probe and readings. Neptune has always been good about servicing my stuff. If you want, I would be happy to let you borrow my Hannah checker or maybe someone’s who is closer to you and you can compare its reading with Red Sea and APEX that can tell you where your true reading is more likely to be. Your tank is still brand new and pH probably will not be where you want it during this stage and before dosing etc..... Your pH eventually will look like a nice wave form on the APEX app- ranging to high in the middle of day lights on to a low at night when you run the refugium on a reverse cycle when your tank gets established. But it should not be a huge swing, just a small swing back and forth depending on the time of day. The most important thing about pH is stability, not necessarily a perfect pH, but a consistent pH.
