Understanding alkalinity and ph---the easy way.

Posted 07/04/2017 at 09:11 AM by Sk8r

"In chemistry, pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity of an aqueous solution."---wiki. Ie, is your water acidic like lemon juice---or alkaline like a desert pool?
On that scale, battery acid (ph of 1) and drain cleaner (ph of 12)---both extremes can burn.
Your tank should be between 7.9 and 9 for the comfort of fishy skin and gills.

BUT--- ph in a marine tank wanders all over the map during a given day. Pretty...

Preventing ich and disease in new fish

Posted 02/22/2017 at 08:45 AM by Sk8r

The importance of water quality IN QT as an ich preventative.
I'm personally not a fan of medicating in qt in the absence of visible symptoms. The species I keep (smaller species like gobies, blennies, and damsels, basslets, etc) influences this decision: no thin-skinned critters like angels and tangs. So your mileage may vary. Take that into account. Angels, tangs and rabbits are very vulnerable.

However, I am fanatic about water quality 24/7 for new fish. Keeping alk around...

About skimmers: y/n/maybe? Not your swimming pool skimmer...

Posted 02/17/2017 at 09:48 AM by Sk8r

About skimmers: y/n/maybe? FYI And they aren't your swimming pool skimmer...
A skimmer produces skimmate, a brownish watery to dark murky yuck that otherwise is dissolved in your water. It does this by frothing the water, and the more efficient skimmers churn the water into a foam that would stand like meringue in a cup. Do you want this stuff gone? Well, lps and soft coral will consume a bit of it. But unless you have a packed reef, their usage can't compete with a skimmer. And, catch-22,...

The evolution of a living tank...FYI

Posted 01/17/2017 at 04:50 PM by Sk8r

There was a time the earth was pretty much rock and water.
Somewhere, probably around volcanic deep sea vents, in the pores of the rocks, life got started, chains of amino acids, dna, rna, etc---and we got, yes, slime.
We got algae.
We got cyanobacteria which happily took up carbon and water and spat out oxygen after absorbing energy from the sun (photosynthesis)---this was a bad thing for things that didn't like oxygen, but it was good for, well, everybody who wasn't a microbe...

Slime coats---important for your fishes' health.

Posted 01/11/2017 at 10:38 AM by Sk8r

Slime coats and you...yes, they matter.
Fish have an insulation, a slime/moisture that coats their bodies and protects them from both iffy water acidity and chance encounters with parasites; it also may limit bleeding in injury and promote healing of minor scrapes.

Things that diminish the slime coat: the alkalinity of your water being out of bounds (the range should be 7.9-9.0 on the dkh scale, and if you aren't testing your alkalinity weekly, you should be. Daily, when just...
