i was using a cpr bak pak and i thought it worked fine, but when i swithed to a tank with a sump i got the ex skimmer and it does'nt seem to skim very much. i know its cheap but should i take it back and get something better and what do you reccomend. 65 gal rr
tried again and same result.instructions say that reading means my kh value in dkh is 16.0 and alkalinity is 5.71. any info on how to drop these levels to NSW.or do i have a bad test kit
im using a salifert kit so what does mean about my system . im using a knop c calcium reactor for about 6 weeks and my effleunt is reading 6.8ph and tank water ph is8.2 thanks
effleunt ph was at 6.4 then went up to6.8 im at about 30 bubbles per minute or as close as i can get with my regulator. its an old blueline. the lowest i can get the PSI on it is 19. which a little high but should be ok
