Hmmm...this is why I love Canreef....I probably should have run my idea through here before jumping in.

Not sure the block has to be under pressure but will have to investigate that.

As for how it will work...not sure again (I obviously like flying blind) but my water already looks pretty clear from the prodibio so I was just thinking a little extra polish couldn't hurt.

Many carbon blocks normally used in RO systems are 0.5 micron. Regardless of pre filter, which will clog pretty quick if it's also fine, the carbon block will likely clog up in short order. I'd be interested in how long it goes though, could be wrong. I'd be more inclined to deal with carbon in a bag or container, agitated by flow that's already being produced by return pump or other powerheads rather than a dedicated pump just for the carbon. Don't find rinsing the fresh stuff all that much trouble.

I thought I would throw a few coral pics up on the thread cause that's what I've been working so hard to get started. I was just hand feeding some of my LPS and you'll see it in the pics.

Wow! Handfeeding is certainly working out for you! I love that first one.

Great pics and did u try the salmon roe yet

They go crazy over it Harry....but its tough to regulate portions so I only give a tiny bit per week.

Thought I would throw a FTS in the thread today. Gonna look a little different soon as I've got a few frags on their way.

Nice purple rock. I'd say you're ready for a schwack-o-frags.

Yeah, it's funny but my lighting during pictures really makes my rock look purpled up. But the truth is that it's not. It's got an average amount of coraline on it.

As for frags...I already feel like things are getting crowded...so 13 frags will really change things.

Many of them won't make it into the tank anytime soon...they have to go through QT and I'll be gone to MACNA this coming week so not much will happen till I get back.

I will send you some big frags after MACNA. Remind me please. :)
