View Full Version : Cursed tank?

I've had a 40breeder fish tank over 4 years with little to no success. I only use ro/di water, my ammonia nitrate, nitrite, are all undetectable. Salinity at 1.225 and Temp siting at 78 currently. But I'm always having issues.

If you don't want the full story; my problems consist of maintaining ph which is always low, and growing/keeping alive coral and fish, plus algae blooms occasionally.

Goals out of this post:
Maintain ph as a permanent solution instead of constantly dosing, reduce algae, fish and coral growth and longevity. All this with relatively affordable methods and 1 time fixes. ( if I have to constantly dose, I'd rather look for other methods before settling)

After about 2 years of not having any fish I felt like it was time. So I had moved my one orange spotted watchman goby over to my 40 gallon tank. He has been to hell and back and has survived in this tank for months. About a week ago I bought 2 clowns thinking they were hardy enough to survive. 1 died after 3 days of heavy breathing and the other I just found dead 7 days later (my guess is from a ph problem because is read 7.4 this morning). So I'm super ****ed and looking for solutions.

On the coral side of things. I have a thriving mushroom colony which started with 2 head and now has around 7 after maybe 4 months. A orange chalice coral which seems to just survive, no signs of dying or growth. But I did lose a 2 mushroom colonies and a favia all bought at the same time 4 months ago. Lastly a torch about 2 weeks old which shows full extention.

After all these deaths and money spent bring up my main concern of being able to have coral and fish thrive. I don't want to put things in my tank knowing they won't last long just to have a fully decorated tank like many people do. I want to be successful so I am open to suggestions. My biggest problem is that I'm a college student who has his dad looking after the main tank till I'm our of college in 2 years.


Other possible helpful info:
2 coralife dual t5 36" with 4 month old bulbs. 2 actinic 2 10 daylights
800gph power head,
Coralife super skimmer hob 65
Emperor 400 filter with phosphate floss
Water changes don't have a set schedule but usually atleast once every week and a half. (More if algae bloom starts)
Glass cover because my dad won't allow it to be uncovered

Tank is located in a area about 20 ft from a wall with doors and windows but they are always covered and unless I am home no one goes to on a regular basis ( I'm skeptical that this might be the ph problem)


So for the cluttered mess called my post, I went back and forth editing to make sure I include as much info as you may need. http://uploads.tapatalk-cdn.com/20161231/179d336c0fcc6dd8f6636df7f16494e4.jpg

Is salinity 1.225 or 1.025?

Covered means very limited gas exchange & IMHO could be the source of your troubles since there is no sump.

Low salinity and oxygen exchange are things you can look into.

I've personally never wanted a cover but it's not in my apartment so, I'll have convince my dad to let it stay off. I think he cares more about the humidity it'll let off do to evaporation than anything else.

As for salinity I just keep it at around .022-.023 because that's the middle of the safe zone on my hydrometer. But if that's a major problem I can keep it high

This was my thought as well

Very likely an oxygen problem.. However, shouldnt the skimmer give enough gas exchange?

Maybe point one of the pumps up so you get a lot of surface agitation to see if that improves.

whoever told you that 1.022-1.023 is correct for a reef is wrong. That's ok for fish only but not a reef. Shoot for 1.026 and use a calibrated (with calibration fluid) refractometer. check refractometer calibration before every use.
