So what am I doing wrong?

[ThatGuy]

So my tank is still not up to par and I don't know why. When I added my 20L sump and put the bigger skimmer online things just went all hay wire. I lost some SPS , the LPS are not fully inflated, and the zoa's and softies aren't opening fully either.

When I built the sump I used GE SiliconI for the baffles and let it cure a full 24hrs. When I put it online I thought I had enough water bud did not so I made up some saltwater real quick and didn't wait for the the temp to come up or the salt to fully dissolve so it clouded up the water for about a half hour.

After that is when everything came spiraling down. All but 1 snail were in the sandbed hanging all the way out but still alive(when I went to pull them out they retracted) so I put them in my FO. Then I noticed the one feather duster wasn't coming out and the other one's feeding apendages were curled up like ribbon. Then I had a Mass die off of brittle stars(probably all of them), they just all came out of the rocks and were blanketing the sandbed. At this point I did a water change so I could siphen them all out. Then I noticed my Long spine urchins spines where all broken shorter than my short spines like it was given a buzz cut.

So about a week ago I decided to take all my rock out and give it a good shake in a bucket of tank water and when I touched the urchin its spines just crumbled.

Now I have SPS that are still colored up with 0 polyp extention(acro's & Monti's), LPS that aren't inflating fully, and the zoa's and softies are all shriveled up looking. Fish, shrimp, and hermits all look fine and the RBTA looks great as well.

Now that I pulled all but one astrea snail out I start having a algea outbreak. At first it was hear and there, but it didn't take long to cover most of the rock and glass and any frag sitting on the sandbed.

At this point I got a cleanup crew from reefcleaners and outside of the snails my wrasse has picked off they are all doing fine. Not doing so great with the HA but they're doing something at least. Also added about 30lbs of sand(rinsed in tank water) that added maybe a 1/4-1/2 inch to the depth.

Now I'm running 2 reactors(one has seachem SEAGEL and the other has BRS GFO), and a tunza9011. My lights are a 6bulb(4atinic 2 10k) t5ho fixture that are on about 10 hrs a day. I have 2 noname powerheads at 1300 gph and a return at 900gph. Also have some cheto in the sump with a 10gal standard fixture over it.

My parameters are

Phos-0(algea's probably using it all)
Alk-9
Cal-400
Nitrates-0
Nitrites-0
Ammonia-0
pH-7.8

Also tested for copper just in case and it is negative.


Any help at this point would be GREATLY appreciated as I'm about to hang up my hat on this whole reef thing and put my lemonpeel angel and chocolate chip stars in the tank.

Not here long enough to give expert advice but you need to get your calcium up. Not that it would explain all or any of your woes, I personally like 460 or even a tad higher. If you do that you need to do a two part. Adding calcium will decrease your carbonate/alk. So add both in proportion. I would also check your Magnesium, helps with alk/ calcium balance and is needed in coral/ invert skeletal growth. A good level for Mg is 1360-1400. Your battle with LHA will require ongoing water changes and making sure Gfo/ phosphate binders are current and not exhausted.

Do not give up, learning is part of the hobby. Even if its frustrating

How old is the tank?

I upgraded it from a 42 to the 75 back in November.

I wonder if the silicone was not fully cured? or maybe silicates from the new sump? I went through almost the same issue back in 2004. I had built the sump and added it to the system the next day. everything died on me. luckily i was not into corals back them but did loose a lot of fish. Wish i had a direct answer for you.

Do you clean your substrate? Blow detritus out of your rock? What is your WC schedule?

There definitely was no release of silicates! Although silicone caulk contains the element silicon, for it to be released would be a total destruction of the chemical structure of the caulk…..not going to happen unless you’re burning it.

However, part of the curing process is the release of ammonia from the caulk. You can actually smell it! If you do not allow ample time for the caulk to cure, you will see an ammonia spike in the water.

Didn't loose any fish. Fish are great.

Up until about 3 days ago I barely had a substrate. It was bare in spots. I did turkey baste the rocks about once every other week. Since the sump was put online I did take ALL my rock out and give it a good rinse in a bucket of tank water.

The caulk says "exposed to water 12hrs, fully cures in 24hrs". I went over 24hrs(maybe 26hrs)

The ammonia also spiked at 2.0 and dropped back down in about 48hrs. But that was right when I put the sump online.

Reading through the whole thread, I have a few comments/suggestions:
1. I agree with Pete about Cal being a bit low and the suggestion to test for Mag too. He's also correct about the relationship between Alk and Cal and that you need to keep both in check if you dose for either.
2. I'm going to go one step further and note that your alk (pH) is a little low also. Not terribly low, but you want to aim for around 8.0 to 8.4 (8.2 would be optimum) if you can. Considering the fact that your Cal and Alk are both a little low, you may want to look into a 2-part dosing system to raise both of them. Just make sure you don't raise either (or both) of them too much too fast. Quick changes can be fatal to fish and some corals.
3. If you have hair algae, then you most certainly have a phosphate issue. Yes, you are correct that the HA is probably using it up and creating a low reading on your tests. What's your feeding regimen? You could be over feeding and causing this issue.
4. If you added a poorly mixed batch of saltwater when you added the sump, it's possible that it precipitated from adding it in too quickly. When you mix up your saltwater, you should sprinkle or sift it into your mix container so that it doesn't add too much at a time. Adding a big bunch of salt at once will cause a chemical reaction where it will precipitate and cause calcification. (I'm sure Paul can elaborate better on this subject). But the point is, it's bad to dump in salt and mix it quickly... it can mess up the water quality. And, adding a quick mixed batch to your system can become a problem for the whole tank as it circulates.
5. The small amount of ammonia that may have been added from the newly cured silicone probably wasn't anything major. It could have caused a temporary annoyance to your corals, but that small amount should have been converted to nitrates pretty quickly since your tank was established and surely has the necessary bacteria to convert it.

Hope that helps. Sometimes it's a combination of little things and not one specific thing that can cause things to go south.

1. Don't dose. Doing the 5 gal a week water changes keeps it all stable right around where it is. Been thinking of dosing but didn't think it was getting low enough to the point it needed to be dosed. Guess I should start. Any ideas as to the easiest way to go?

2. I did take action for the pH and got Seachem Marine Buffer. Only dosed once so far and plan on doing it again in a day or two as I don't want to raise it to fast.

3. HA has slowly been dissappearing.(thinking the rock shake out helped that) There are only a few small spots that looks like a buzz cut vs. long choking strands. (Hoping it all goes away). As far as feeding goes I give either a cube a day or a half cube and a pinch of daniche pellets. I don't think I'm overdoing it, also don't want to under feed as I have some aggressive fish that I don't want looking at other food options.

4. Yeah I messed up there. Its not a normal thing. I just rushed to get enough water in the tank so it would start flowing through the sump as the heater is down there and I didn't want the tank temp to drop to much.

5. I thought any ammonia was a catistrophic thing(Was the culprit). But I guess not as it was only for a day or so and not a constant.


Thanks
