    White spot on top fin of clown fish under QT

    Just got 2 clown fish, and have them placed in a 9 gallon QT tank. On one of the fish, there is a small white spot, the size of a grain of sand on the top fin. I'm sure this is a common question that comes up. I'm new to this I would hope to get some help to ID if this is something that...

    dKH "stuck" around 7-8 range

    I've been trying to raise my dKH, and it's been difficult getting past dKH8.5. I'm dosing B-Ionic two times daily, about 16mL of each part in the morning, and about 8mL of each part in the morning. At one point in time, I had been dosing close to 20mL of each solution twice a day. Even then...

    Turboflotor blue skimmer and water level

    I'm using the Turboflotor Blue skimmer in my 130D, and it skims extremely well when it works. However, I find that it's super sensitive to the water level; maybe all skimmers are - but I haven't the experience to know. I believe one of the causes is I'm having a lot of algae slowly dying off...

    Sand turning black, bubble coral not opening fully, cyanobacteria in 3.5 mth old tank

    My tank is about 3.5 months old now. And I'm running into a few problems, I'm stuck on at the moment. 1) Part of my sand is turning black on top. Lightly stirring the sand shows a sort of slimy coat (or at least something causing the sand to clump together). Is this cyano? - Photo...

    Corals look weakened w/ bleaching, low dKH, how much buffer to dose?

    I'm new to the hobby, and my tank has cycled for nearly two months now; and I'm gradually stocking up on coral. Up until about a week ago, all additions to the aquarium have been doing fine; and since adding my most recent additions and a water change - a few of the corals seem to have less...

    Best way to use ChemiPure Elite in 130D (no media basket)

    What is the best way to use CPE in the 130D? I currently only have a small bag (not the red-sea bag) of carbon in the chamber of death. Could I just throw a bag of CPE over top the carbon? Does require the majority of water to flow through it or some leakage is ok? I know the in tank...

    Metal in Caribsea aragonite

    Just cleaned the glass on my newly cycled tank with a magnet cleaner the other day, and I noticed the magnet picked up a number of black metallic pieces from the substrate. The pieces got stuck in the cleaning pad, and even left a bit of rust. I'm using Caribsea aragonite as substrate...

    Anyone using LiterMeter or Tunze metering pump for auto WC?

    Does anybody here have any experience using either a LiterMeter III for a constant water change, or Tunze metering pump for semi-automated water change on an RSM tank? I've read about someone using the metering pump + a switch to toggle between SW refill and regular ATO. My only concern is...

    ID - possible aiptasia?

    Just found this developing on one piece of my LR. Referenced some photos, and I'm thinking it may be aiptasia, can anyone confirm? When probed/touched, the tentacles curl up into a ball. I did not see it retract into the live rock. There's a bunch of these growing. Current size is...

    New tank, starting cycle - questions

    Just started to cycle my new 34gal tank (RSM 130D), and have a few questions: - I started by preparing the saltwater, then rinsed and added sand, then left for a week before adding live rock. I've been reading some suggestions to add the sand last (after the cycle) to keep it clean. I'm...

    ATO sensor above heater compartment - potential overflow?

    I have the RSM 130D and the Tunze Osmolator; though I guess this would apply to any ATO system. I've seen a few people install the ATO float in the space near the heater compartment. I currently have it installed there too; but I'm thinking what if there was a clog or obstruction of the...

    Power outage backup plan

    Setting up my new 130D, and creating a backup plan in case of power outage. At the moment, anything within about 2-3 hours will be done with a sine-wave output UPS power supply, in addition to the Ecotech Marine battery pack for my MP10. I am thinking about heating issues beyond 2-3 hours, and...

    Cleaning up new aragonite substrate dust mess

    Just added Carib-Sea Aragonite substrate to my tank last night, and the water is really cloudy now. I did rinse the aragonite with RO water, though I didn't have enough water to wash until clear. I did between 2-3 rinses per each small batch of substrate added. Did some reading and my options...

    RSM 130D pump and MP10 noise

    Just filled my new 130D and mixed salt-water. I'm finding one of the stock water pumps a bit noisy, and I'm not sure if it's just the location of the pump. The pump closest to the left side of the tank is fairly silent with a barely noticeable hum when turned on, however the other pump (on...

    New 130D setup questions

    Just finishing up assembling my 130D, and I've got a few questions: 1) Where should the gray air-hose for the protein skimmer go? The manual says "thread pump cord and hose through the cord access hole". I know it goes to the top above water to draw air, but there are about 4-5 inches...

    Dimming 130D fluorescent w/ new ballast and Apex controller

    Has anybody successfully modified their RSM 130D to be able to dim the T5 fluorescents via an Neptune Apex controller (or any other controller/dimmer)? I know the stock ballast does not support dimming, and the Neptune Apex can dim nearly anything that has the 0-10V interface. It looks...

    Moving 130D full of water and LR

    I'll be cycling my new 130D soon, but will need to move the whole thing a few feet in a month or so. I get a feeling moving the aquarium when full is not really recommended. The floor is a hardwood floor, and I was thinking about adding some adhesive felt pads to the bottom of the RSM stand...
