Will, people will be more than willing to help you out. We just need some specifics from you to help diagnose what might be going on for you. Take your time, compose the breakdown of tank specs, Equiptment, and maintenance schedule for us. Do you dose? What type of mechanical filtration do you have? Do you run a skimmer?

All this will help us help you

RODI unit is only 2 months old Also 145lbs liverock with major purple encrustration of coraline

 

[Shane and John]

What is your bio-load? How often and what do you feed?

 

[Shane and John]

Do you have a TDS meter hooked to your RO/DI?

 

[senji]

do u have a tds tester id check quality of ur ro water to start with. start at the supply and work forward. i keep all me 55g barrels at 50deg with an 8inc blue airstone no movement pump. and i keep it in the barrels for months at a time with no blooms. as for keeping the res at tank temp i think ur asking for trouble with algae. with my experiences. i heat my water 6 hrs before using it.

 

[Will]

just started dosing kent marine tech part a and b 2 days ago calcium at 390 trying to raise

 

[senji]

use kalk wasser to raise. goes great with auto top off

 

[Shane and John]

I didn't mean for it to be kept tank temp at all times. I just hoped he wasn't putting 72 degree water straight into his system.

 

[Will]

no td tester at current hope its good i also use for my coffee and such

 

[Will]

actually am putting 72 degree in main tank Major problem? I have extra 300 watt heater if so

 

[senji]

yea id heat all water to 80 deg. before useing it. dont store at that i keep all my water in the garage so it stays cold. can have neg affects on corals specially sps.

 

[Shane and John]

Will, it would appear to me that that would cause a big temp swing If you were to change out say 10 %. That could flex and swing your temps a lot. Corals will slime if stressed.

 

[Shane and John]

Water going in should match water going out. Same temp and salinity.

 

[Shane and John]

If you run your tank at 77 degree your make up water should match that. If you heat it to 80 degrees it would swing it the other way. Does that make sense how I explained it?

 

[Will]

So is using this water every week keeping my nitrates at 10 to 20 ppm Or is tank not completely cycled after 8 weeks

 

[senji]

do u have livestock?

 

[Shane and John]

I would think its NOT completely cycled. I would do a very Large water change then test after 24 hrs and see where your test results are.

 

[Shane and John]

do u have livestock?

Good question!!
