Yeah it is quite a bit of flow. Sure works well though.

Yeah mp20s would be useful. I'd like an mp40 eventually for my 75 build but really something in between the 10 and 40 would be great.
You did not read that wrong or I did not leave a zero out :) MP 2

The thought crossed my mind you might have meant that but I figured it was a typo lol.

So how much flow are we talking here? like 350 gph?

Why not 250? MP 2.5's :thumbup: 3's do sound better though.
My bubble coral could not survive in my 5' long tank with more than
one MP40 thrusting a little above idle. 2 MP40's at the minimum thrust
was too much for it.

Well you could turn down the flow to 250 lol.

MP-3, that would catch on.

Was the glass/acrylic too thick to use mp10s?

I need to get me an MP40 for the 75 gallon lol.

Not too thick no, the pr of MP40's were basically free :biggrin::bln-wow:

With a MP10 yes but not on the 40's I had.
Those you can turn down to 1,000 gph each and that's just not enough for me.
Plus at 250 gph you'd be idling with no thrust, so a fixed prop
would be more money wise.

I meant using the fictional MP-3 lol.

Okay short update.

Tank is doing fairly well. Two of my three red planet frags have partially bleached, or at least significantly lightened. I believe it's because I removed too much detritus and got the tank too clean; I tested the nitrate at about 2 ppm, I didn't test the phosphate. It seems as if my light was too bright, and possibly calcium and alkalinity too high (though I'm leaning more towards the lighting). I typically keep the nitrate around 4 ppm, the orthophosphate around 0.08, alkalinity at roughly 8.5-9.0 dkh, calcium around 410-420, and magnesium tends to sit around 1400. My levels when the bleaching/lightening occurred were very likely closer to 2 ppm nitrate, 0.04 ppm phosphate, alkalinity/calcium/magnesium roughly 8 dkh/410ppm/1400ppm. I believe the light is to blame as I have little reason to believe that the levels fell outside a somewhat acceptable range, I believe the bleaching was simply caused by excessive light given the cleaner than typical conditions.

Aside from the two of three red planet frags (third red planet frag is chugging along just fine, and is about 2.5 inches deeper under water, and about the same distance sideways from the center of the light fixture. This adds weight to the excessive light theory.) the only coral affected visibly is the green birdsnest which has also lightened significantly in certain areas. All three affected corals still have colour, and are starting to recover; polyps are out and stuff, and the colour is coming back ever so slowly.

The montis, stylos, birdsnests, the single Lepto, and two random acros I don't know the name of were more or less unaffected by all this.

I'll post photos later today, or possibly sooner if you guys bug me for them.

Okay update after 9 days.

The two red planet frags that were bleached have started to regain colour. I upped the dose of red sea reef energy, and let the nitrate climb ever so slightly to about 3 ppm or so.

The other day I did some coral pruning; the green stylo was starting to shade out the Montipora frontosa so I clipped two little nodes off and glued them in the back of the reefscape; you can't see them now except for from the side of the tank. In time they will sort of fill in this crevice in the back. I'll take some photos later.

The green birdsnest was getting quite close to the red planet acro so I clipped several branches off of it and glued them further left of the birdsnest colony to try and widen it out in a different direction; I'll take some photos of this as well later.

I also clipped two roughly quarter sized bits off the green Montipora capricornis and glued them in the back as well hidden from view when viewed from the front, but visible from the sides and above.

Time for an update.

Tank is doing great; the red planet frags that bleached are almost entirely recovered, and I'm seeing a more natural amount of polyp extension. All corals are currently doing spectacular except for the blue Tenuis Acro which has seemed happy for months but literally not grown at all (so obviously isn't as happy as it looks) it hasn't receded either, and it looks pretty so that's good, but it would be nice if it grew. it has nice polyp extension and a nice colour but refuses to grow. I'm not going to change anything for this one coral though because everything else in the tank is doing great, and it isn't like the Tenuis is STN'ing or anything.

I received a TLF kalk reactor that I purchased from fellow TRT member Pmarkj; I'm waiting on the tunze switched socket outlet so I can install it, but I've sort of mock set it up in a bucket to test how it works, and see how well matched the mj1200 I have for it is, and it seems to work like a charm. It isn't as heavy duty as a reef octopus for example, but I think it's going to do it's job really well.

I've been needing to dose 2 part in addition to the kalkwasser in my ATO lately, I've been having noticeably less evaporation now that the weathers getting warmer, I think because it's more humid. The alkalinity currently is dropping about 0.1 dKH a day without the 2 part additions. Hopefully the Kalk reactor will make a dent in that so I don't have to dose as much. If not I may be looking into a dosing pump set up at some point because I need this tank to be simple to maintain while I'm going to university. My mom is happy to feed the tanks for me, and she is capable of cleaning the skimmer cups, and that sort of thing, but water changes and dosing are sort of left to me. It would be nice if the tank could go 2 weeks with no intervention other than feedings.

TLF kalk reactor is installed, and seems to work well. I'm using my tunze osmolator with the switched socket outlet, and an MJ1200, and the pump seems very well matched to the reactor; it stirs up the kalk at the bottom nicely, but doesn't push it up and out of the reactor, even if it runs for a long time.

I cleaned all the calcium carbonate build up out of my ATO reservoir, and I forgot how shiny and clear it is lol.

Here's some photos:

Quick update, for the past month or so I've been nuking what I thought were pest anemones left and right. I realized eventually that they are secreting calcium carbonate skeletons, and that they are in fact settled pocillopora polyps. I stopped kalk pasting them to death once I realized this and several of them are growing at a nice pace.

It's really nice to think you have a major aiptasia problem, and then to figure out that not only is there zero aiptasia in your tank, but you actually have settled coral polyps all over your tank. Pretty neat.

I'll post a photo of one of the polyps that has settled out and begun growing shortly.

Thanks :)

This kalk reactor has been keeping my calcium and alkalinity almost completely stable, I'm testing alkalinity with the hanna checker every few days and I nearly always get the same test result, some of the corals seem to appreciate the stability, while some don't seem bothered either way.

Update, The blue acropora tenuis is very slowly dieing, It has polyp extension still, but it has never grown (in several months), I suspect it spent some time in a very dirty tank, which 'poisoned' the skeleton with phosphate or something, dooming it to a slow and arduous death.


...Okay I know it spent time in a very dirty tank because I owned the tank.

All the other corals (seriously, every single one) are doing great, growing quickly with great colour, so I'm not concerned. The tenuis still looks pretty, but I know it won't last till 2017.

Update, removed the tenuis.

I've had to cut back various corals as they start killing each other, so photos won't show all the growth, but it'll give an idea.







All of the green monti you see above is new growth on the mother colony on the right side of the tank, it seems to put on at least a cm of new growth maybe per week or so.

I'm officially running into the issue of too much growth, It'll be very good to get the 75 gallon sps ready in the next few months so that I don't have to start throwing out frags, because seriously, I'm running out of stuff to do with them, and the nearest LFS that can take them off my hands is about an hour drive from where the tanks are, and about 2 hours from where I am currently. Eventually I'll bring them in a nice bag of corals and see if they'll trade me something for them.

Update time!

Tanks doing great, all corals except my red Montipora frontosa are doing awesome. The frontosa is growing at a decent pace still, but the polyps seem to be nonexistent. It's weird because typically in my experience when you never see polyp extension day or night it's a sign the corals days are numbered, but the frontosa seems to be growing still. I think it's just stressed from being so close to multiple different corals, but that's just speculation. There's definitely competition for space in the tank though. I did find a single limpet in the tank about a week ago that could be munching the polyps maybe, but it was promptly removed just in case. I haven't seen any others. The red colour on the frontosa is still incredible.

Everything else is doing great, including one acro that I've had for months that has only recently starting growing. It's starting to sort of table out, and is starting to look really nice. The growth is quite quick.

I have one birdsnest colony that is slightly larger than a soft ball, it's starting to look pretty impressive.

The red planet acro frag that was slightly bleached has more or less recovered, it's about a half inch away from another red planet frag, and I really want them to grow into each other so they form one large frag and perhaps start branching out.

I have 5 more frags ready for transfer to the 75 gallon, but I'm weighing the odds of them doing well prior to flow and light upgrades in that tank. I have a montipora test frag in the tank though and it seems to be doing alright.

I'll have photos later today or tomorrow.
