Background

Always been keen on Fishkeeping and had a Tropical Tank for a while. Moved onto Marines with a small 90l tank, which gave me the confidence to understand the water and how to maintain stability. Took the plunge with an RSM 250, and have been pleased with the results, I use an Apex to monitor and measure,and control most of the critical elements.

I have a TECO TR10 chiller with Heater and UV, as I have a lot of issues with Ambient temperature, I have a Kamoer dosing pump, and I use NOPOX for Carbon dosing, I am heavily stocked so I have to stay on top of everything, especially Water quality so I try to do a 35l water change every 3 days.

I have 2 hoods one with LED's and one with T5's, I have not settled on which is the best for my inhabitants as yet. I use a Tunze Osmillator for ATU

Lighting

I am currently using 2 x Radion Gen3 Pro with Wide Angle Lenses, and this is because I have the Units fairly near the Water Surface. I have the Lights ramping up on a Sine Curve for 12 hours with 2 peaks at Midday, I also have a 50% Cloud Cover Potential and 25% Storm Potential
