sontdo Posted January 16, 2008 Share Posted January 16, 2008 I bought few SPS frags, acropora, which are gone now. My yellow leather is shriveled and is almost gone too. My LPS, zoos are OK. I'm not sure why SPS died. I have 6 Actinic VHO 110W; 2 175W MH; 100G; 15W UV sterilizer; recently water changed 40% of tank; Actinic on 8 hours; MH on 5 hours; 2 powerheads with natural wave setting in the opposit direction. Water condition is good. I would like to get more SPS frags but not sure if they will survive with the current lighting. Should I upgrade my lighting to 250W or 400W MH or add seaswirl for better current. Any input or suggestion would be greatly appreciated.

andy Posted January 16, 2008 Share Posted January 16, 2008 2 powerheads in a 100gal tank? What type? Quote Link to comment Share on other sites More sharing options...
sontdo Posted January 16, 2008 Author Share Posted January 16, 2008 Powerhead: Max Jet 900 and 600 Quote Link to comment Share on other sites More sharing options...
Michael7979 Posted January 16, 2008 Share Posted January 16, 2008 That isn't very much for a 100g tank. Most sps people are well over a 20x's tank volume per hour for flow. For example in my 100 when it was set up it was at 25x's + 600 gph going thru the sump. I didn't think I had enough flow in my tank.

impur Posted January 16, 2008 Share Posted January 16, 2008 Yah i would also say flow. I have over 5000gph in my 75gal not including my return pump. You have about 300gph not including your return pump. No SPS will thrive with that low of flow. Quote Link to comment Share on other sites More sharing options...
sontdo Posted January 16, 2008 Author Share Posted January 16, 2008 So do I have another powerhead? or what do you recommend? Quote Link to comment Share on other sites More sharing options...
Nyles Posted January 16, 2008 Share Posted January 16, 2008 I would add two maxi jet 1200 with sure flow kits... one on each side of tank. That would cost you about $70 total and draw 40 watts of power. Quote Link to comment Share on other sites More sharing options...
andy Posted January 16, 2008 Share Posted January 16, 2008 If you prefer to just pick stuff up locally, a couple of Koralia 4 stream-style powerheads would be a good start (though they're less efficient and cost more than Nyles' suggestion).

sontdo Posted January 16, 2008 Author Share Posted January 16, 2008 thanks for the input. Just clarifying: I add 2 Max Jet 1200 in addition to the current powerhead MaxJet 900 and 600. what direction of water flow should I aim for. I can only put powerheads in the back of the tank and not on the sides. Do the SPSs need to be high, medium in the tank. Thanks again guys.

Nyles Posted January 16, 2008 Share Posted January 16, 2008 optimally you should get the pump facing each other this will create variable current.... here is a pic of mine taken some time ago but they still work wonderfully (I just run 2 on each side in my 155). http://i112.photobucket.com/albums/n184/nyleswright/Reef%20Tank/10-23-06003.jpg Quote Link to comment Share on other sites More sharing options...
Nyles Posted January 16, 2008 Share Posted January 16, 2008 you could mod the 900 as well if you like, the kits are $15. as far as position it really depends on your lights, with what you have I would start them half way up and if they don't color up well I would shoot for raising the frags up. As for flow just don't point the powerhead at the coral at more than 12" away, I like to keep mine at the top and I have on pointing towards the center back to keep waste in suspension on my 72" long tank. You won't be able to put the powerheads down low because they will blow the same all over in that 20" deep tank, if in fact thats what it is.

sontdo Posted January 18, 2008 Author Share Posted January 18, 2008 I have MaxJet 900 and 600 pointing toward each other in the back of the tank, in the center back. Should I add 1200 or another 900 in the back, pointing to the front of the tank? Where can get a reasonable price MaxJet? Online usually is less expensive but have to wait.

impur Posted January 18, 2008 Share Posted January 18, 2008 I think Nyles was talking about MJmods, where you mod the Maxijet with a RC boat prop similar to Tunze pumps. This really ramps up their output, the MJ1200 stock is like 196gph, after modding its more like 1500gph. If it were me, i would add 2 of the Sureflow mods, or go with a couple Koralia 4s in there. This is the link to the Sureflows http://www.marinedepot.com/ps_ViewItem~SearchStr~~action~view~idProduct~AF1551~idCategory~FIPHAC~category~Algae_Free_Sure_Flow_1600_Maxi_Jet_Upgrade_Kit_Saltwater_Aquarium_Supplies_Powerheads_Accessories~vendor~.html Quote Link to comment Share on other sites More sharing options...
sontdo Posted January 18, 2008 Author Share Posted January 18, 2008 thanks for the website for sureflows. So should I get another MJ 1200 pump in addition to what I have now: 900/600. Thanks. Quote Link to comment Share on other sites More sharing options...
andy Posted January 18, 2008 Share Posted January 18, 2008 I'm gonna chime in and recommend the Tunze Nano Streams (here, for example). They're a bit more expensive, but their mounting system is, imo, the best out there. You can place them just about anywhere, and point them in just about any direction. Koralias come a close second, but don't have as wide a directional range. Just something to think about. Quote Link to comment Share on other sites More sharing options...

Thats what I mean... two sureflow kits and two maxi 1200. You can try that and if you feel you need more flow add a few of those existing ones back in, but those two sure flows will completely BLOW AWAY what you have Quote Link to comment Share on other sites More sharing options...
Holly Posted January 18, 2008 Share Posted January 18, 2008 Tunzes are 'spensive but they kick(censored). I have 2 in my 180g (plus 4 Rios, a Sieo, and another pump behind the rocks). Tunzes provide SERIOUS current, and Andy's right about the mounting--with the magnetic mounters it's a breeze and you can move them anywhere. Just my 2cents IMO I'd put SPS in the top 1/2 of the tank. Mine flourish in the top 1/3 of mine (which is 24"D and has 750MH & 624W Actinic03s), and they also seem to like a fair bit of direct current... Good luck!

spectra Posted January 19, 2008 Share Posted January 19, 2008 I really like the Tunze to but my mount broke on mine have to get a new one. I have a few MJs but have not modded any of them yet. Quote Link to comment Share on other sites More sharing options...
ocboat Posted January 20, 2008 Share Posted January 20, 2008 Check out the Triton Aquatics Gulf Stream II kit. They will mod a MJ 1200 to 2500GPH and come with a pivoting mount for $20.00 - $25.00. They really put out a lot of flow and are well made. www.tritonaquatics.com Quote Link to comment Share on other sites More sharing options...
Nyles Posted January 20, 2008 Share Posted January 20, 2008 Im going to close my eyes now, I JUST purchased 6 of the sure flows. Quote Link to comment Share on other sites More sharing options...
reefboy Posted January 23, 2008 Share Posted January 23, 2008 How old is your system hate to say this but I keep sps in low current trays with no problems im thinking your tank may still be abit to young to support acro types if it less then 8 months old and id check all parameters make sure there in check one cause may be fluxing ph and any number of things if your system is young anyways just my two cents check phos as well.

sontdo Posted January 23, 2008 Author Share Posted January 23, 2008 hi reefboy, you're right. my tank is about 4 month old. my LPS is doing fine. I just bought some acros and will see if they survive. I'll have to increase current flow and lighting. Will check phosphorus. pH is OK. Thanks for your insight.

Never hurts to increase flow and lighting( as long as heat dosnt become a issue) hope new additions do well but you may just need to wait abit more and you'll get what you want:D Quote Link to comment Share on other sites More sharing options...
Palani Posted January 28, 2008 Share Posted January 28, 2008 can you use those mj mods with wavemakers? Quote Link to comment Share on other sites More sharing options...
andy Posted January 28, 2008 Share Posted January 28, 2008 You can, but they'll chatter on the power-cycle. The Seio wavemaker should work better. Quote Link to comment Share on other sites More sharing options...
