This question is for us with no grow out tanks, not big time reefers or what have you. Lol. What is a normal amount of growth to be expected for a SPS. I have a birdsnest that I see tons of new little branches coming off from it and my caps seem to double size in a short time span, but I don't...

What is the best way to raise my Ph it comes out of my rodi at 6.8 I would like to raise it to 8.3. Baking soda doesn't seem to raise it very much. Is there anything better?

If anyone wants to sell a little kalk mix or pickling lime or can tell me where I can buy it around the Holland/Zeeland area let me know. I have looked at almost every store around with no luck. I am also looking for anyone selling magnesium additives or test kits. PM or e-mail me at...

There's an article by R.H.F. from 2006 that says raising pH by .4 will cut down CO2 levels in the tank by 50%. This is bad for dinoflagellates which need CO2 to grow. Two questions. 1) Would reducing the CO2 aslo hurt the zooxanthellae in the corals? 2) My pH is 8.0-8.1, I use BRS two part...

Like many reefers, I have been dosing 2 part (and Mg) as well as topping off with kalkwasser. The problem for me was that I was only measuring Alk, since equal parts of Ca and Alk should be needed - I figured I could simply go by the Alk readings. I was wrong. Coral etc. growth uses up Ca and...

I am considering buying calcium hydroxide from bulk reef supply. I running kalk through a deltec stirrer (about 8 liters for my 300 gal system) along with using a calcium reactor I have always used rowakalk product by D-rowa. Is there a difference here (besides 4x the cost)? They both just...

My source of pickling lime (calcium hydroxide) has let me down. I just missed the BRS bulk order. Has anyone actually seen pickling lime anywhere around the I-75 I-696 area? (Or around Detroit and suburbs, for that matter!) Thanks, Mike77
