Hi fencer, do you have an example of one?

DAY 0

Sand Added this afternoon

Particle Size - Not sugar fine sand but the what I have available at the moment. If I don't get any positive NNR I may have to replace. Will also demonstrate how much impact particle size has regarding NNR.

Starting Nitrate Tests

ORP (DSB) = 300mV (dropped to 180mV within 20min of adding sand)
pH (DSB) = 8.00
Drip rate = 0.67 drops/min

The Drip rate above should be 0.67 drops/sec instead of drops/min.....I don't have that much patience.

Lol!

Great project! Thanks for sharing and tracking it!

Cheers,

Day 1

ORP (DSB) = 270mV +/- 10mV
pH (DSB) = 7.29
Drip rate = 0.83 drops/sec

Notes: ORP gradually climbed back up from the initial drop when sand was added. Not sure why this is but I'm thinking may have something to due with flushing out whatever may have been in the sand. Sand was rinsed and stored in a bucket for several week before use.

Live rock is good.
Deep sand bed is good.
Doing at least a monthly water change is good.
Getting rid of the bio wheel would be good
And keeping the nitrates down is good which all of the above will do.
It is nice to see that you are really trying to provide the optimum conditions for your coral.

I think you should take a little time to research the optimum conditions for your fish as well though.

For example, tangs require the longer tanks (6 footers) that larger tanks provide.
Your is four.
Tangs are swimmers. They spend all day swimming back and forth and thus need the swimming room.

No Nitrate tests tonight. Did one earlier in day, and I'm beginning to get the impression that this may take a while.

ORP: 187mV
pH: 7.19
Drip Rate: 0.8 drops/sec

Probably 4-6 weeks.
