    Water quality and livestock addition after huge alk spike

    A few weeks ago, I dosed ESV B-Ionic alkalinity and calcium. I used half the recommended starter dose and my alk went from 8 to 20+ on both the Hannah and Red Sea titration test. I did water changes to try and rectify the spike, but only made it worse using different than normal salt. Alk...

    Cons of topping off with high PH RO

    Basically i got a low PH problem and the way i been dealing with it is feeding the skimmer air from outside aswell as topping off with pretty high PH water around 9-10 PH the way im getting the PH so high is by sprinkling some marine buffer by SeaChem into the RO. Now I'm worried about any side...

    Does anyone know any cheaper ways of testing reef chemistry?

    So I just spent quite a bit on a 25 pack of 5-in-1 test strips. After having gotten home and using 2 already, I realized that the precision of the strips is sorely lacking, and that I could have gotten a 100 pack for a bit less than I paid for the 25 on Amazon. Of course, I had looked before I...
