I like what Lumetek is doing with their ballasts and giving you the option to overdrive or not to overdrive the light bulb, since most ballasts way overdrive MH bulbs. Chris is one of the most impressive people I have run into in many years. He is like a Randy Holmes-Farley when taking about...

I often disagree with some of Antony's chemistry issues as does Randy. I like 8.2 - 8.4. There is no sound reason to have it at 8.6 and many may have issues with Ca++ precip if they let the Alk or Ca++ get up. Unless of course one is trying to control Dino's or say Bryo for a couple of wks. And...

That is a Sphaeromatid Isopod ;)

Again thanks for the welcome and nice comments :)

You must have missed my sig on RC I no longer have tanks. 35 years was long enough ;) I like keeping things near NSW maybe with a slight increase in Alk to 3-4 Meq /l if the pH is in line. lot of people run 8.4 pH, 400+ Ca, 11 dKH Alk, 1250+ Mg..........I'd almost wager that most people use...

You brought it up in your post If you dose washing soda into the tank the pH rises very quickly because there is no CO2. This is not knit picking. I tried to bring you to the next level. There is CO2 unless the pH is above 9.1, with a normal Alk. At pH 9.1 it is ~ 50/50 HCO3 - and CO3-- and at...

No worry Carlo. As many know I'm a grumpy old man:D Often one has to generalize things as they can not often be explained in lay terms. If I see one can maybe go to the next level I go for it. The other issue is this is a hobby and many things can not really be explained. I have draw full of...

Boomer, isn't it specifically high magnesium sulfate and not magnesium chloride levels that people have reported help to control Bryopsis? No, both have been used to in include raising the pH up to 8.5, to limit CO2, with no addition of either to control Bryopsis. The original method was to use...

The pH & CO2 will later adjust themselves to be the same regardless of if you add carbonates or bicarbonates. Granted to a point but that later can be days if it is SA, as it also raises the Alk higher than BS ( a least the way most do it by not looking a weight or Mol values. Even if we go by...

If you dose washing soda into the tank the pH rises very quickly because there is no CO2. This is often a misleading a myth. When ever you add either you raise the CO2. For each eq of HCO3- you add 1 eq of Alk and 1 eq of CO2. When it is CO3-- you also add one eq of CO2 but 2 eq of Alk. When...

Well, I don't know what you mean by high but high Mg++ if brought about by sulfate or even chloride can have good and bad issues. Pro's High Mg++ in either sulfate or chloride forms can help to control Bryopsis and Cyano and is a method used to do so for about a 2 wk period. Con's If it is...
