Water Changes

JR's Reef · Mar 17, 2009

I normaly do 20% once a month but time has not been on my side lately due to my son think he has to play every sport and has been keeping me very busy since fall of last yr. So its been around 4-5 months since ive done a water change

Heavy bio-load I change 10 gallons weekly to keep the nitrates at 15PPM. I also skim 24/7 add KW when needed.

Ok, finally got it to work. I use an ASMg4x along with a fluidized reactor filled with Rowaphos. There is a 20 gallon refugium as well. I dose Tropic Marin bio-calcium and bio-mag. Very little drop off in salinity.

155 bowfront, 36 gallon sump, hob cheap skimmer but pulls skim here and there. No filter socks. 9 watt uv constant and nothing else. Been going for a few years. Top of by bucket with ro/di. Sump all sand, rock macro with t5 on it. Run it oposite as tank lights. Maybe 5 to 10 gallons a month tops. Feed with Rods, and may add little supplements here and there, nothing really tho. Do not add trace elements ever. I just let it run natural and let the tank break all down. Small fish tho, nothing major.

150 stony coral reef running since June, 2007. Made a huge mistake by loading sand from prior 55 nitrate factory into this system. I't been a battle royale with dinoflagellates on the sand (only, not the rock) ever since. Began doing weekly 27 1/2 gallon water changes last June, and I am now winning the battle. GFO has been in play for the past two months, and I believe that is assisting as well.

40g tank with 15g sump and no skimmer. I do bi-weekly water changes. One with 5g and the next 10g alternating. Manual top-off with ro/di a little under 1g a day. Feed a couple times a week, everything fat and healthy. 4 fish. Still a young tank though.

On my 2 tanks I have a 35 g mixing barrel that I do waterchanges. 5 gallons goes to my 65g and 30 gallons to my 225g. About every 10 days.

35g every two weeks on my 115g

I actually neglected to do a water change in my tank from September through January, and just recently started doing 15% water changes monthly. I'll try to get a FTS later today, but the natural filtration in the 200 gallon system was more than sufficient for the 4 or 5 fish it was supporting. I fed about twice a week to get the palys and anenomes some food, but other than that, the fish I had (1 tomato clown, 1 6 line wrasse, 1 watchman goby, 1 yellow damsel, and one chromis) lived off the pods from the fuge and 200+ pounds of LR.

I use to do 10% weekly but now i do it monthly.

cloakerpoked · Mar 23, 2009

Most of my SPS and clam were fairly recent (within the last 2 months) additions to the tank at this point, so the stock that's in there at the time is somewhat misleading. Had a bad bout with slime algea, so I started doing regular water changes with RO/DI water. (before that had been using tap as top off water.) My tank sorta threw a lot of general conventions out the window for the short-term, but recently I've appreciated how fortunate I was to have my tank still in tact, and have begun a lot more responsible reefkeeping practices. Still, never had a nitrate test above 0ppm in the year I had that tank without water changes.
