Hey everyone,
I like to keep my alk at 9.3 and about a week and a half ago I noticed my Trident started reading higher and higher so I started by lowering the DOS threshold. I kept doing this more and more but it kept increasing and now I have completely turned of my DOS for alk and my alk is continuing to increase and go up. Currently it is at 10.54 and as I said the DOS is completely off. I have recalibrated my Trident and have done more then one test and it is showing the same.
I really am not sure why this is happening, so I will give you some background on the tank.
It is essentially a very large frag tank (My version of a display tank is a frag tank because I enjoy the coral propagation fun) the dimensions at 72"x36"x12" and it has no sad and only coral racks in the tank. The only media for bacteria I have is Marine pure and brightwell blocks in the sump. I also have a refugium with a ball of chaeto that is being tumbled by a powerhead and is slow growing. I 3D print the racks with PETG material which is reef safe. I run an Eshopps skimmer as well and 2 filter socks and 1 bag of carbon. I have only dosed aminos twice and I dont have a ton of corals atm (still paying off my bills from the new tank lol) This tank has been running for probably 5-6 months at this point. I ONLY use RODI water and use a 25 gallon Brute can filled for top off.
I do water changes every 1-3 weeks as the tank stays fairly clean with the filter socks and refugium and skimmer going plus with no sand most particles are suspended.
Please see my levels below.
Phosphate: .05
Nitrate: 18.2
Alk: 10.54
Cal: 413
Mag: 1333
salinity: 1.024 (going to bring it up a point or 2 next water change.)
Any thoughts everyone? If there is any info I missed or any info you would like to know please let me know and I will answer as quick as I can.
Regards,
