no prob fishface, let me know if you have anymore questions

what are you using to feed your reactor Colin??

I have the marinetech reactor with two chambers and since i never owned a reactor before the lack of instructions didnt help. proline helped alot though. Id try them.

i'm using an eheim 1262 i think it is

got a problem. just tried hooking this unit up and got a leak between the pump and riser tube, at the volute specifically. when i talked to Jason he mentioned to lube o-rings with silicone which i did but low and behold i've got myself a fairly substantial leak. i've already tried to remove the silicone to see if it made a diff but nada. any suggestions peeps?

when the unit is apart can you see and hairline crack anywhere? what about burrs along the oring mating surface. if there is any burrs just file them down with a file. inspect the oring all away around to make sure it is perfectly round, if there is a flat spot anywhere replace it. sometimes when the unit is assembled the oring will get pinched or actually rip a piece of the oring off.

The 1/2 inch is for a probe...Mine didnt come with any instructions,,,,,,Thanks Jason for the Reator 101 lesson!

so i've got a question for those who may be in the know. i've seemed to iron out the operation of the reactor for the most part, now it's time to tune it. i've read a bit and from what i gather, it mentions to get my alk in line and Ca will follow. well, alk seems to be rising but can't keep up with Ca, it's dropping rapidly to the point i had to add turbo Ca.

numbers as of today are: Ca 380ppm (and falling) alk 6.8dKH and rising and Mg 1380ppm. can anyone tell me what the deal is here?

no advice :sad: from anyone??

i would say both Alk and Ca need to come up. i suggest increase effluent by half and do the same for co2 as long as your ph in reactor stays around 6.7. i had the same issue and when i did this it brought both up evenly.
