I guess lots of time have gone by to judge these bulbs. I tried the250 watt MH 10000k ;i did not like them too yellow. I got 20000k and i like those. I am wondering how long do they last before spectrum shift .
Anyone out there used them for a while and can tell their experience.
Should i run them with the front sreen on or leave off. With the screens on the flow is more straight ahead with them off its more of a turbulence. What the consensus with or without front screens?
Do i increase water flow, increase amount of bubbles or increase cleaning of the skimmer riser tube? Which one will lead to better skimmer operation.
I read that skimmer should have low water turn over to allow bubbles to have longer contact time. However i can't see how this remain true when...
They pull lots of air when near the surface so a empty tube at the top of the koralia would pull in air.
It could also be used as a recirculaing pump as they are quite popular with skimmers these days.
Anyone try placing a koralia inside a skimmer and using it to produce bubbles by adding an airline where it can suck in air.
I notice in my reef when a corallia sucks in airit produces a tremendous amount of tiny bubbles . I figure they would be great inside a skimmer.
I agree pods like to eat if you feed they will multiply , sometimes to very great numbers.
Predation take out a lot of pods, depending on fish in the reef tank. Especially if you seldom feed the fish.
Unstable parameters such as sudden rises or dropping of ph
It become difficult to remove once it start spreading. Hard to get rid of i tried hyper magnesium treatment ; it kills it. Like to find a fish that likes to eat it.
Best to replace , In my opinion a MH Ballast should last at least 5 years if its not electronic. The old technology may not be power use friendly but they last a long time
I notice that my leather coral have their polypt extended most of the time . However sometimes they will not extend for hours. (usually not a whole day).
