Yes, although if you needed to decrease illumination you could use the same method that you do for your T5s. For dimmable fixtures, I usually opt to either ramp up to full brightness and down again or just run for 8 hours at a brightness that is in equilibrium with fertilizers / co2 added. I didn't...

Both units at the same time? I run mine 8 hours (2x T5 HO) with a 1-2 hour overlap of (2x-T5 HO). I guess I can run the LEDs full time

The ray2's put out a lot of light but I doubt you'd just want one. I use 2 on an 18" tall tank that's 18" front to back. It's just about perfect for high light in that setup. Your 90g is a few inches taller, so figure from there. I'm thinking the same thing, my tank is 18" wide and 2...

Shahriar, it all depends on the height of your tank and what lighting level you want to achieve. For a shallow bookshelf tank (8" tall), I really liked my Satellite PRO. The Plus Pro outputs roughly double that so it could work for a high-light tank at a bit more depth. For tanks more than 12-...

One other option, the Penn Plax Cascade canister filter. I got one of these when Scales was in business and it hasn't had a problem yet. I have since bought 3 more and they are all quiet, dependable, and pretty easy to clean. I am surprised not more people use them. The 1000 can be had for less tha...

If you're looking to grow carpeting plants, make sure the light you choose can produce a minimum of 60 PAR at the distance from the light to the substrate THROUGH WATER. Some manufacturers list their PAR through air which is deceiving. If you stick between 60-100 PAR at substrate, you should be abl...

Thanks, they are really inexpensive filters!

How do you like the Satellites? I'm considering the Satellite Plus PRO.

For the G, you're pretty much stuck with their mechanical filtration. Plus side is I haven't had to replace that for over a year on mine with regular cleaning. You can simply remove their chemical filtration blocks and use Purigen or other medium (charcoal bags, etc) in its place. I do use Purigen ...
