Frustrated. My tank still looks like c**p.

Flanders "“ I'm not buffering at all. I have no calcifying corals and I would have thought that 5% water changes every week would have been enough to keep the alk up. I also have an aragonite sand bed of about 3"; wouldn't that contribute to the buffering capacity as well?

IMO, you should be buffering. alkalinity will gradually drop in all marine aquariums over time. water changes are helpful, but unless the new water has alkalinity elevated above NSW levels, or they are very large, they cannot be expected to restore your alkalinity without additional buffering.
 
JMO.

in the case of a Seahorse tank you should grow macroalgae in the display. This is where Hippocampus occur in nature and this is what the aquarist should strive to re-create.
Water changes are not as crucial in a pony tank as a reef aquarium and your alkalinity could easily be buffered up with a supplement. Avoid unusually high (500ppm) levels of calcium.
 
Wonderfully, perfect thread for me Flanders! Thanks!

So it looks like I’ll be dosing. I want to keep things simple and there is no room for anything else under the stand. What would be a good way for me to dose? Something I won’t mind doing – maybe add it to the top off water that I add each day? I did a quick look around on Marine Depot's site and I was wondering . . . do I have to do the 2-part if my Ca is already high? If not, what else would I use? Just sodium bicarbonate?

I agree wholeheartedly! I did have some macros a while ago, but I had some shipping issues so they didn’t make it. I was actually planning on trying again sometime soon. Even if I end up not keeping the seahorses, the (dwarf) angel I get someday will be very happy. Yes?

You guys are the best!
 
Kept coming up with the part of the human brain.
Heh. I can only imagine what it might come up with if you only typed "erectus" :eek2:

I tested the DT this morning using my API carbonate hardness kit and I got a reading of 8-9 dKH. That's a good normal reading isn't it?

I'll be doing a 10% water change tomorrow and I'll test again after to see if it goes up at all. Mostly just because I'm curious.

My rocks are such a lovely shade of brown. :bum:

8-9dkh should be fine.... i thought the target was 8-11ish?
 
What about flow? Would increasing the flow help the situation at all? I have an Eheim 1250 (maybe 250gph w/ head loss) and a Maxijet 600 (160gph). The fuge will add another little bit, but not much and it will be toward the surface - maybe another 150gph.

Wow, that's only 660gph total. Although it is around 10X tank volume. Certainly not enough for SPS or LPS and maybe not enough to keep the nasties from growing on the rocks?

do you visit the Seahorse and Pipefish Forum on RC?

Sygnathiids have special requirements...

and Angelfish are usually considered a no-no in a Seahorse aquarium.
 
there can be excessive flow in certain areas of a seahorse tank, the only things they need are places to rest or hang out.
That's what I learned as well. There have been folks who have had significant amounts of flow in their seahorse tanks, but it was very broken up - ie spraybars, closed loops, etc. The advantage I have since I've had them for a while is that I know where they like to rest during the day and at night so I could make sure to minimize water movement in those areas.

Sygnathiids have special requirements...
Definitely! I have had three years to research these guys before I even started setting up the tank. That's also why I've been putting up with some other issues as I don't want to do anything that would be bad for them.

Angelfish are usually considered a no-no in a Seahorse aquarium.
Yeah, they are def. a big no-no! Bullies and would hog all the food for sure. No, I mentioned an angel because, should I decide to re-home the seahorses, I have a coral beauty on my wish list. Someday.

So. All that being said, would increasing the flow help me out with the lovely brown . . . whatever . . . that is everywhere? I really need to post a pic. I'll try to do that today.
 
I think I have a couple (three) things going on here
1)bit of slimey cyano on a couple rocks and small areas of sand
2)dinoflagellates on dead rock
3)some type of slimey brown algae (?) that is on some rock and likes zoas (figures!), but the rics are fine.

So, after reading and discussing, and reading some more, here's the plan . . .
I'm going to start with cutting my photoperiod and as soon as possible get my 'fuge going which should be this weekend. After a couple weeks, if I still don't see improvement I'll start running GFO.
