Log of Scrubber Progress

Not bothering to seed the screen there are already small bits of algae stuck to it. DAY 1 Params: NH3: 0 NO2: 0 NO3: 0 PO4: 0 Ca: 440 Mg: 1260 Screen: DAY 2 DAY 3 DAY 4 DAY 5 DAY 6 DAY 7 DAY 8 DAY 9 DAY 10 DAY 11 Did the first clean. I only cleaned one side – the lit side (opposite to picture). Not a lot came off but I got rid of some errant cheato that was stuck to the screen. I have also moved the light to be much nearer the acrylic. DAY 23 Cleaned the unlit side. This side has by far the least algae on it – still, I was quite surprised to get a good egg cup full off of it. No noticeable changes in the display algae infestation as yet. DAY 24 Here it is the day after the near side clean. As you … Read entire article »

Not so Dirty Little Scrubber

Algal Scrubber added – I will take readings later although PO4 and NO3 are usually zero. The proof will be in if it can compete with the algae in the display. Ignore the piping and light this side of the curtain – this is my return with a tee off into my skimmer. The light pointing down is for my cheato. Things I did do: Built the frame to slot over my sump with 5mm clear acrylic. Cut the 25mm pipe with a Dremel cutting bit to about 3 to 4mm. Fix all joints with PTFE (may glue them at some point). Took a tee off my sump return with 1″ pipe to feed it. Moved the curtain from off my DSB so it drops down between my baffles – it was disturbing my bed too … Read entire article »

Hearth Urchin

New arrival. A sand bed cleaner and stirrer – quite an unusual subject for the job a “Hearth Urchin” (Maretia planulata). They hide in the substrate during the day and come out at night to feed on the surface. … Read entire article »

Bumble Bees

Added 10 more Bumble Bee snails to the main tank. My originals are all doing well and seem good little omnivores. They can certainly get to the parts other detrivores fail to reach. Did my first water change ever yesterday as part of filling the Nano with 50% new salt mix and 50% mature tank water. About 40 litres. Have a possible purchase planned for tomorrow. All might be revealed. … Read entire article »
