    Hello reefers, I have a 50g reef tank, still new (3 months old) with some LFS and some snails & hermit crabs. No fish yet. I added a shrimp 2 weeks ago but didn't survive even if i made sure to acclimate it well. I tested my water last week and today again. Parameters are: ph 8.2 dKH 5 mg/l...

    ran a water test and noticed my ph was a little low - 7.4ish, maybe a little higher. I had heard about using baking soda, but wanted some advice before I ran out and put anything in my tank. I know I can get all sorts of "ph correct" buffers through an LFS or online. however I'm a bit low on...

    What does this mean? And, more importantly, what can I do about it? My alkalinity tests are off the chart (higher than 3.6 meq/L), but my pH is frighteningly low (around 7.7 or 7.8). I don't have a calcium test, my tank is 20 gallons, very new, still cycling, cuc and live rock in it right now...

    Do corals use par to grow or to stay alive? 20,000K bulbs have low par, which means they won't grow as fast, right? So could a low powered 20,000K bulb have so little par that it won't even keep corals alive?

    my calcium (390ppm) and alkalinity (6dKh) levels are low in my 29G BIOCUBE. i've heard that dosing with PURPLE UP will help raise both these parameters and then once they get in range i could switch to a 2 part buffer like B-ionics. is this true?
