Just opinions of other reefers who can draw on their independent experiences to try and provide the OP with some suggestions that may have slipped past them based on their own experiences.

every system is different and to just write off anothers suggestion purely based on your own experiences really isn't helping anyone out here...IMO.

+1, well said

Try changing your salt maybe. I think sometimes that these mystery slow/no growth problems come down to a trace element that we might not even know to test for. Some salts may have it, others not but it's worth a shot.

As 6 hours of light may be enough, this will all depend on the quality of the fixture, bulbs and age of things... Maybe try increasing it to 8 hours, and give it a month and see what happens, then maybe 10 hours.

I personally use Ushio 10K bulbs for growth with t5HO actinics and have my lights on for 11 hours with no negative impact and the corals seem happy.

Just another suggestion if you feel other areas are ok.

I'm running PFO Ballasts and reflectors for all three lights. 2 of the bulbs are creeping up on a year old and one is a couple of months old. I started putting corals in when the bulbs were about 2 months old and growth was non existant through the life of the bulbs. I moved all the corals under the bulb that's only a couple of months old when I installed it. No change to date. The two older bulbs are Hamilton's and the newest one is an IceCap

I should also mention I have a VERY low bioload.

Wow that's all? I'm not one to boast about growth but I know fish poop makes for one good coral food. Any other things added to the water for nutrients?

Yep, that's all I have the intention of getting more, I just need to find the right fish.

Sorry, I missed the second half of the question, nothing else is being added to the tank.

This is something we have in common. I have a yellow tang, 2 small clowns and a tilefish. I'm going to increase it to see if that makes any difference.

You know, there might be something to this. Marie grows SPS forests and she maintains a nutrient rich tank. Aside from a top-end skimmer she doesn't use much else. Not even filter socks.
