Ghl or apex

[Toongraeme]

So I'm looking to have it do the basics. Lights, temp, ph, possibly calc reactor, but more than likely adding a doser. I could kick myself, I had a ghl slave, but sold it as I didn't think I'd go that route. I might also go led and I do run tune power heads. I know I need an adaptive for tune on ghl. But what I've seen so far is if I don't have the initial investment in the apex, everything is an add on..... I'm swayed to wards ghl, but at the same time know apex is so readily available here....
