Anyone know if this has been tried?

Weird. What test kit did he have that was unable to show the difference between 0.25 ppm and 0.0 ppm ammonia?

Not sure.

Might have been Salifert

Latest cleaning (5th I think)



The green is filling in a lot more now with much more long strands of hair type stuff. It seems tougher too, more was left after scraping.

The yield was down a bit though - I have been getting 140-170 grams (5 to 6 ounces) per week of drained gunk, but this week it was only 110.

I've pushed the lights forward about an inch, after backing them off 2 inches last time.

Continue to dose iron - Added quite a lot but have only been able to get the test up to 0.25 so far, aiming for 0.5. At this rate though it's gonna be a costly exercise, unless it's "filling in" and will eventually find a level. Have to find a cheaper source of iron.

Feeding a bit more this last few days, 2 cubes a day plus a bit of flake and will continue with that.

Latest cleaning (6 days this time as I'm not around tomorrow)




Bit more green, yield the same as last week though, 110 gram drained.

Perhaps that is all I'm going to get from the amount I'm feeding?

At the moment I'm feeding 2 x 5g cubes per day plus about a gram of flake (and this week have fed one 8 x 8 sheet of nori too)

So that's 70g of frozen and 7 grams of flake per week. The flake label says 8.8% moisture, so if once rehydrated it became 5 x that (a guess) weight that would make it equivalent to about 5g per pay or 35g/week, meaning that I might be scrubbing out a similar amount to that which I'm feeding in?

The hair algae in the tank appears to be receding anyway.

Bought a Salifert phosphate test.

Shows zero (on the sensitive scale which tests down to 0.015)




Must be working than.


GHA still growing on the rocks and on snail & hermit shells too (as phosphate comes out I assume). Anyone know how long that lasts?

A few months.

Filling in nicely now



Yield's back up too
