The Shrimphaus gets some light brown coloured algae-like material growing on the glass which needs periodic scraping off. It won’t just rub off casually, but it comes off using a credit card blank relatively easily. It does seem to happen more in regions of higher lighting. It isn’t super unsightly, and doesn’t happen fast enough […]

I have been using an Asta 20 nano LED light on the Shrimphaus, and that’s been fine but it’s a point source light so there’s not much illumination at either the back (shaded by the river) or the right side (furthest away). Today I swapped that out for a new Week Aqua S400 Pro aquarium […]
Read more →Appropriate aquarium lighting is critical to the success of a live-planted tank. The Fireplace Aquarium uses a 15W Kessil A80 Tuna Sun LED light which has both lighting intensity and colour programmed with a Kessil Spectal Controller. This gives a pretty reasonable blend of time on and time off. The plants and animals seem happy. […]
Read more →Nothing has really dramatically changed in the Fireplace Aquarium but I feel the green spot algae has been growing back quicker than it used to. I was having to give the tank walls a credit-card scrapedown every three or four weeks, but now it seems up to every other week. I tried increasing the dose […]
Read more →Simulated daily light programme My daily lighting sequence with the Kessil A80 LED light controlled by a mains timer was pretty straightforward: lights off for 18 hours per day and lights on full for 6 hours per day. That’s fine but of occasion I’d head into work with the lights off and they’d already be […]
Read more →Advantages of a programmable aquarium lighting controller With the Kessil A80 LED, or most other aquarium lights, you don’t actually need a programmable controller, however, without a controller your options are to hand adjust light and colour twice a day, or more practically, to manually set the light and colour and then plug the light […]
Read more →Following up on observations of changing fish behaviour when either lighting or flow rates are changed, here we take a look at what happens when the lights turn off. The video shown starts after the Kessil A80 light has been on for nearly 6 hours, the typical photoperiod for the current setup. The tetras and […]
Read more →In transitioning from a low tech to high tech tank I noticed a significant change in the behaviour of the fish* where they used to swim mostly at the top/middle regions of the tank under low tech conditions but then spent a lot of time at the bottom with the high tech conditions. At the […]
Read more →I’ve been running the Kessil A80 light for 6 hours per day on the maximum intensity. The aquarium looks nice either with the lights on or lights off so here are some contrasting photos. With the lights on, the fish tend to stay at the bottom of the tank. With the lights off they are […]
Read more →The Kessil LED light and LED lights that come as “point sources” rather than as strips of lights can have a feature called “shimmer” which is where they make ripples of light on the bottom of the tank. I’ve never really observed that with my set-up in the past, attributing that to not having the […]
