Hi all,
I've kept a reef tank for nearly 3 years. I upgraded just before Christmas to a custom built L shape which holds 725 litres (192 us gallons) of water. I set it up with new rock (aquaroche), new sand (aragonite - not live) and Natural Sea Water. I had 4 x mantis bio blocks and live rock in my sump which I transferred over to the new tank.
I didn't dose in my previous tank, mainly because it wasn't required until just before I upgraded. For the new tank I wanted to dose from the start as I planned on increasing my amount of corals with the extra space available.
I'm in the UK and looked in to different options and eventually settled on Oceamo Duo.
Initially I was testing daily and dosing the suggested amount by the distributor here in the UK. Levels were good but then started to rise faster than they were being consumed. At the end of January we stopped dosing either of the duo but, since then, my calcium has risen to 540 and magnesium to 1665 (from 450 and 1335 on 29/01). My kh has fallen however, from 10.1 to 7.7.
This has thrown up a lot of confusion for me! Is it possible that something is leeching the calcium and magnesium back in to the tank?? I'm not running any other medias, just a Clarisea and skimmer in the sump with the bio blocks and live rock.
I'd really appreciate any help/advice!
Many thanks,
Gary
