Question
I bought a house with a small ( I'd say 5x3 and about 2 1/2 feet deep) backyard pond. The pond was uncared for all winter and had no pump. Three goldfish survived. I drained the pond, cleaned up all the yuck and refilled it and installed a pump suitable for the gallons. When I first filled the pond the water was fine, but when I had to step down in it to situate the pump, I noticed a couple areas of white plume like areas shooting up white water. Within minutes it made the whole pond milky white. I thought it may settle within 24 hours or so but it hasn't the water is still milky white. What could have cause those initial under water white plumes and can I fix it without draining it again. I worked really hard on it all day and would like to create a pretty spot where the fish could thrive. It's so hard to find out any information about this. Thank you in advance for any advice you could lend.

Answer
Kindly check the SI(Saturation Index ) As Parameter listed below.
Low calcium hardness will often result in the loss of grout around the tiles, as the

water tries to satisfy its need for calcium.
It is necessary therefore to maintain the TDS at sensible levels (ideally no more
than 1000 mg/l above the feed water ) and yet maintain an adequate level of
calcium hardness in the water (around 200 mg/l minimum ).


The formula for calculating the Langelier Index is as follows :


pH + Temperature factor + Alkalinity factor + Calcium Hardness factor -TDS factor

And is applied using the table below to obtain the factors from the actual test
results for Total Alkalinity, Calcium Hardness and TDS.
