Growth problems

Twice a week, I dose using aquavitro liquids and seachem powders.

Not saying that is totally your problem but dosing twice a week vs. daily or multiple times a day probably isn't helping.

Take for instance your KH drops from 10 -6 before you dose, then at one shot you pump it back up to 10 by dosing. While yes your KH is back in line, the swing between those days and the rapid increas probably adds some level of stress to your corals.

Are you saying you are running one pump for your chiller and return to your tank? I would think you'd loose a ton of head that way. I have a deticated pump for my chiller and one for each return. I doubt that's what's causing your problem. But I like redundancy in case a pump goes down I'm not up a creek. Check out the rio hf series they are cheap , small, and have gph head.

Yea I have the eheim running through the chiller into the tank. I have a jbj chiller, is their a better way to run the return?

O yea I totally agree with you about dosing daily rather than twice a week, but the aquavitro instructions stats only to dose it twice a week. So any suggestions with that?

Interesting. Can't say i am familiar wth their supplements though i do use their salt. Seems a little odd though that it would tell you to dose twice a week though I looked and sure enought that is what the instructions say. Seems a little counterintuitive to me. I will say i dump dosed for quite a while (B-ionic and eventually homemade 2-part)before I went to a calcium reactor and eventually back to dosing via dosing pumps and timers. I account much of my more recent success with evening things out.

CheckitOut, weekly dosing is probably too long for SPS, it either cause big swing on ALK, or for few days in the week CA is too low.

You may also want to dip some of your coral to see if you have flatworm or red bugs.

Eric, I just about to ask a question of daily ALK dosing schema, will open a separate thread in SPS forum.

Agree.....

Going back to my earlier post.....first thing to do is test daily for a week or two. Test some a.m. and some p.m. to get a good feel for how your params are swinging. Then you can figure out how to adjust your dosing.

Also, for the return, I split mine with a "y" connector. One side feeds the chiller and then flows into the return. The other side goes directly into the return. That probably at least doubled my return flow.

I'm not sure on the MP's since I never had them. But, you could research it a bit and try to determine your total flow rate.
