Tank Of The Month – TOTM December 2019

190 Gallon SPS Tank from Janne Koskinen, run by the GHL System

Tank owner: Janne Koskinen
Location: Tampere, Finland
Display size: 150cm x 80cm x 60cm /Approx. 59in x 31in x 24in
Display volume: 720 liter/190 gallon

My name is Janne Koskinen and I’m from Tampere Finland. I got my first tank a 60 liter (15 gallon) freshwater tank 42 years ago. The hobby was a lot different back then. It took many years to learn to keep livestock and we’d go through lots of fish before finding success. It wasn’t until about ten years ago that my interest went to the salt water side. I’d read many horror stories of reef keeping which made me apprehensive. About three years ago, I decided to get rid of the last of my freshwater tanks and take the leap into reef keeping.  In looking back, I believe my many years of success in freshwater tank keeping helped me be more successful in reef keeping.  It’s been an incredible journey with lots of ups and a couple downs but I truly have no regrets.

My tank is SPS dominant with some LPS. This tank has been up and running for about two years. The sump is about 350 liters (90 gallons) and measures 120cm x 60cm x 50cm (47in x 24in x 20in) and has a built in 50 liter (13 gallon) ATO reservoir.

I use a Jebao DCS9000 pump for my return pump. I run two Tunze 6095’s, a Tunze 6020 and a Tunze 6015 for internal flow, a Deltec protein skimmer, a Deltec Calcium Reactor and use Phillips Coral Care lighting.

All of which are controlled by my ProfiLux 4.

For me, it’s all about my ProfiLux

It controls everything on my tank and I really mean everything. My lights, dosing, return pump, Tunze Streams, Protein Skimmer, Cooling, heating, etc. made it so my tank is “set it and forget it.”

My GHL Powerbars

control everything that can’t be controlled by 1-10V interface or other PAB devices.

The PLM-ADIN card was an inexpensive addition to my system that provides me digital inputs which I use for the following:

1. Feed pause, turns of skimmer and streams
2. Maintenance mode (one hour) turns off skimmer, return pump, heaters, kamoer, a solenoid valve, calcium reactor, ato and doser that feeds limewater stirrer etc.
3. Second maintenance mode that does the same same as two above but for two hours
4. Floatswitch in skimmer cup which turns off the skimmer if it starts to overflow.

The GHL LBF-AP

controls my Philips coralcare lights giving me more options to control lights than Philips software.

I decided to buy the KH-Director package

with a GHL Doser 2.1, when I switched from three-part dosing to a calcium reactor.  GHL KH Director® made tuning my calcium reactor quick and simple since it eliminated the need for manual alkalinity testing.

When I first set the Calcium reactor up, I had the KH-Director testing my alkalinity eight times a day. The frequent tests of the KH Director allowed me to see the results of the adjustments to the calcium reactor quickly and without the need for manual testing.

I ran the KH Director at eight tests per day until I had the calcium reactor dialed-in.  Now the KH Director only tests alkalinity in the mornings and at night giving me peace of mind knowing that my system is running optimally.

My GHL Maxi Doser

is used for Kalkwasser additions on one head and the second head is used to add a bit of salt water to the tank to replace the salt water that the KH-Director removes for measurement.

My GHL Doser 1 is used to add Fauna Marin Color Elements.
