Thinking about giving up! Please help!

Alright. I appologize for the delay but I have an update. I purchased a Kent Marine Maxxima Hi-S 35gpd unit. Unfortunately I only get about 5gpd out of the unit. I also purchased a dual TDS meter. It shows about 750ppm on the input side and 0 on the output side. My final stage is already changing from blue to orange so I am betting that this will be a very expensive unit for me to operate.

I've been running this unit and performing weekly water changes for three weeks now. When I started using the new water, I also added ChemiPure, Pura cut-to-fit filter, and PhosBan. I noticed some immediate changes. First, the red planaria reduced to about half of their previous numbers. Additionally, I noticed that the green slime algae almost completely disappeared.

Unfortunately, shortly after switching to my own RO/DI, my Hydor Theo heater malfunctioned and kept my tank at 89 degrees for nearly a week. This is the second time I've had a Hydor Theo heater fail in the last year. Even straight out of the box both of the heaters heated nearly degrees higher than indicated on the dial. The only casualty of this latest failure was that my Xenia melted. I ripped out the expensive Hydor heater and replaced it with an El Cheapo and slowly adjusted the temperature back down to 78 degrees.

I am still having a huge problem with algae, although it's a type of algae I've never dealt with before so I'm not really sure what to do. It seems to thrive in the top layer of the sand as thousands of tiny filaments up to two inches long. The filaments eventually attach to air bubbles and then float around the tank until they smother my corals with a mesh of the tiny filaments. These filaments are much smaller diameter than a human hair.

When I do a water change, I blow the crud off of the rocks with a turkey baster. After doing this and vacuuming the sand, the water is absolutely filled with the tiny filaments. At this point, they're a sandy, tan color. As soon as I get some water put back in, I turn on the filter and try to mechanically remove as many of the filaments as possible. Inevitably, the corals still end up covered in the stuff. I then turkey baster everything again and repeat until I no longer see much of the algae. Unfortunately, after three weeks of fighting this battle, I'm not seeing any decrease in the production of this algae. Any tips on what this is or how to get rid of it?

Of note, the green slime algae is now gone. Unfortunately, my Caulatrea started breaking suddenly. I loose 2-3 polyps every week. The polyps themselves seem healthy, but the skeleton is crumbling.

As for parameters, I've tested both the RO/DI water straight out of the filter and the tank water. All parameters are excellent. The only thing that I find a little strange is that my RO/DI water fills with micro bubbles when I add the salt. It take about 30 minutes to clear. Is this normal? I've never seen this behavior with LFS water.

Again thank you all for your help with these problems. I'll try to keep everyone updated.
 
sounds like all you really needed was an ro/di unit. I had one for a 55 gal. I was running, but then gave it away as I moved. when I set the tank back up it was algea heaven. I couldnt stand it. I broke the tank down and let all the rock dry out untill it was white. I bought a new ro/di (which my first one was the same one you bought) and then set up my new nano. I have not had any algea probs to date and I'm using all the old rock from my previously algea infested mess. One other thing I noticed after setting up that 55 in a diff tank for my mom was that the algea was there but the tank equilized and suddenly the algea was gone.... now this was only after her finally leaving the damn tank alone. So your options are this..... 1.) break the tank down and dry all the rock change the dsb 2.) leave the tank alone for awhile and let it equalize while you use the new ro/di unit.

I really recommend a euroreef skimmer, I have two between two tanks and they work great. I had an aqua c remora but they are overpriced and they are crap. however even with that skimmer which is still on my moms tank, it eventually equalized and controlled its own levels.

Be patient, I know you love this hobby. You know to much to turn back now.

Good luck.

Wow. 750ppm for your imput water is aweful!!! Here in Chicago our water is about 200ppm going in. I am wondering about your 5gpd output of the RO unit. Do you have a low pressure well system or is there a way you can measure the input water pressure? You should get more than 5gpd from a 35gpd unit. This thread is full of useful information so you should be back on track soon. I would just like to reiterate: Water changes...lots of them, Clean the filter pads out daily, PO4 remover, carbon or purigen always. Also try not to blow the algae around when you do a water change, try to suck it out. If it does blow around, clean the filter pad ASAP afterwards. Good Luck.
 
I bought my ro/di unit on ebay. Its a 7 stage that has the 4 gallon storage tank, auto top off, and even the thing for the sink to dispense good drinking water. Believe it or not it was only $100.00 + $50 for shipping, and I got 5 replacement cartridges as well. WHAT A DEAL, it was hooked up in seconds and runs great. This beat my old maxima hi - s that was only 35 gpd and worked like crap.
 
i would invest in a good ro/di unit, sure you can use bottled RO but it will become a pain down the road and you have no idea when they replace their filters. Distilled would work as well, in the end you will probably end up buying a unit so buy it now. from there i would turn the lights off for a few days, more would be better (if you have no corals). after that i would take a turkey baster and loosen all the algae from the rocks and sand, scrape the glass as well. do a 50% w/c, do this for about 2 weeks, and problem should be solved, and no chemicals are added to your system. I would also consider adding a couple turbo snails. This method has never let me down.
 
Things are looking up...but not for the filter...

Things are looking up...but not for the filter...

Again, I just want to thank everyone for their helpful responses. I now have what appears to be a much healthier tank although I am still fighting some of the same old algae growth on the sand. I upped my cleanup crew and they're helping, but not quite enough to keep me from having to pull it out. Most of my corals are quite healthy although my Xenia and Frogspawn are not nearly as extended as they used to be. Hopefully they'll improve soon too.

My main question is about my Kent Maxxima 35gpd Hi-S RO/DI unit. The Deionizing filter has a color changing section at the bottom. The unit came with no instructions (and no membrane, but a call to customer service got that corrected) so I'm not 100% sure what the color change means. Does it mean that I need to replace the Deionizing filter only? In any case, I'm quite disappointed at the life I have gotten out of the filter. The color changing portion was completely changed after only about 30 gallons of product water...that's less than the advertised full day's production! On top of that, the unit only produces about 10-15 gallons per day. I have uninstalled and reinstalled all fittings and filters but the output remains the same. My water pressure is between 55 and 65 psi and according to my TDS meter it runs about 650-750ppm. I know this is high, but is it so high that I should be seeing these results? If that's the case, the cost per gallon for this water is prohibitive. I'd be looking at about $2-3 per gallon!

Please let me know if you have any advice on what I should do. Thank you very much (again).
 
Wow, 650-750ppm is crazy high TDS. I have crappy well water and it's only in the 300's.
That's why your burning through your DI Resin.

I would go to The Filter Guys forum on here and ask what he thinks. He was very helpful when I talked to him. Maybe he has a solution or advice.
 
blaklite, I fought a very similar algae issue last year in my tank. I tried water changes, phosphate remover, chemiclean, etc. Nothing ever removed all of the algae. The longest it would stay gone was three days then it was back to blowing it off with a turkey baster and scooping up what I could. I finally found a link on ReefCentral (that I no longer can find but this one is referencing the same issues http://www.reefcentral.com/forums/showthread.php?s=&threadid=988473) that recommended turning off all lighting for 48 hours and covering the tank. I did a thirty percent water change after this blackout. After 48 hours you could have four hours of for your photo period for the first month As long as NOTHING came back, you could add an hour per week until you are back to your normal photo period.

If you see any sign of the algae returning, do the process over again. My tank was overran with this stuff so badly that I was at the point of quitting. It's been eight months so far since I did this and no sign of it. I left ALL of my softies, LPS, fish and sebae anenome (sp?) and did not loose any of these. My SPS however weren't so fortunate
