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)
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.
