A healthy aquarium is a balanced one — water chemistry, filtration, stocking and feeding all work together, and most fish problems start with the water. This page gathers the fish and aquatics library of KinsLe Answers in one place, organized by topic for freshwater and saltwater keepers alike. Every answer is original, written by KinsLe, and tied to a real KinsLe feature.

Proof comes from a dated series, not a single snapshot, and four records build it: the purchase date with the size at purchase written beside it, dated photographs taken against a fixed measure inside the tank, a dated length estimate entered each time you measure, and the same four fields repeated in the same order…
Take a records set built on five fields, kept identical every time: dated test results, an onset and progression timeline, recent additions to the tank, feeding details, and dated shell photographs. Test results should name each value you measured and the date you measured it, the timeline should say when signs first…
Send a handover note written for a keeper who knows nothing about this fish, covering seven fields in this order: species and present size, food type with amount and timing, usual tank temperature, normal test readings, the water-change routine in plain steps, quirks and companions, and any health history worth…
Photograph the group from the front at feeding time, when the fish gather on the substrate, then photograph individuals from the side and above, where stripe, spot and fin patterns separate one fish from another. Add one photograph of the whole tank floor, since cover, open sand and flow shape where each fish spends…
The repeatable record has five fields every time: the date, the percentage removed, the replacement water's temperature, the conditioner used, and how the fish behaved after refilling. Make the percentage physical rather than guessed: mark a line on the glass for a set share, or count buckets of a known size out of a…
File each notice in date order in one folder, paper or digital, kept with your tank logs, and highlight the effective date rather than the arrival date. Write five things on the front of every notice: the date it arrived, the effective date, the change stated, the tanks affected, and the action you took. The first…
Keep two linked records, a dated move-event log for every addition, move and rehoming and a current stock list for each tank, and give the move-event log exactly six fields: date, fish identity, source tank, destination, reason, and acclimatisation method. Give each stock list exactly four fields: tank name, fish…
Record the same fields at every check so entries can be compared directly: date; a photograph taken in the same light and from the same side; the exact change seen, in plain words; water test results from that day; any change to decor, tank mates or routine since the previous entry; and direction since the previous…
A fry record earns its keep when another keeper could repeat the batch from it, so use the same fields at every entry: batch identity and hatch date; food type and particle size at each stage; number of feeds per day; water change volume and frequency; size estimate for the batch each week; and losses since the…
Keep one log entry per move, with the same fields every time: date; fish moved, by count and description; source tank; destination tank; reason for the move; acclimatisation method and duration; water test results for both tanks that day; and follow-up notes on feeding, behaviour and losses for each of the seven days…
Shortly before you leave, test a healthy tank and record the baseline set in full: ammonia, nitrite, nitrate, pH, and temperature, using your own kit's values exactly as you read them. Note the equipment state beside it, with the filter running and the heater steady, and write what counts as off for the sitter, such…
When snail numbers jump, record the date you noticed, how you are feeding — food type, amount, and frequency — and anything else that changed in the previous weeks: new plants, a new food, a feeder used during a holiday. Compare each boom with those earlier entries, because the surge usually follows the change rather…
Keep one calendar for the whole tank, because the plants and the fish share one body of water. Give every entry the same fields: date, liquid fertiliser amount, root tablet and its position, pruning or planting done, light period, water change amount, fish feeding and behaviour note. Written together, the entries…
Log every quarantine day at the same time, with nothing added to the water: the observation itself is the whole method. Use the same fields for each entry: date, appetite and food eaten, behaviour and tank position, breathing at rest, waste appearance, visible marks or changes. Write what you actually see in plain…
Give every purchase its own batch code and never let a batch exist only in your memory. Record each batch with the same fields every time: batch code, arrival date, source, number added, generation label, parent batch code, berried female date, colony photo reference. The generation link comes from the berried female:…
Track a goldfish's growth from photographs taken against a fixed scale, so the fish never leaves the water for measuring. Fix a ruler strip outside the glass along the fish's swimming lane, photograph the fish side-on beside it from the same position, and record length from snout tip to tail base. Take a top-down…
Record each paired test as one entry with exactly six fields: the date and time of the test, the parameter tested, the result from the first kit, the result from the second kit, the expiry status of each kit's reagents, and the action you took. Never average the two results or drop the reading you like less, since…
Keep the pond log by season as well as by date: enter each test with its result, the water temperature that day, and what was happening — feeding level, weather, filter cleans, any treatment or bulb change — so spring readings can be compared like for like with previous springs. KinsLe's Pet Passport keeps those pond…
Create one album per fish, and give each album the same four parts: a clear photograph of the left side, a clear photograph of the right side, a close-up of any distinctive markings, and a dated note recording the fish's size. Photograph every fish against the same plain background, name each file with the fish's name…
On the same day each month, write exactly three lines for your betta and take one photograph in the same light from the same position. Line one records where he rests. Line two records his appetite, described by how eagerly he comes to food and whether he finishes it. Line three records his colour and fin condition as…
Keep one combined log where every weekly entry carries exactly eight fields: date; light period; intensity setting; change made; glass score; rockwork score; plant-leaf score; and feeding or fertiliser change. Score each of the three surfaces from 0 to 3 every week, change only the light settings or only the feeding…
Keep one pond log where every test entry carries exactly ten fields: test date; season; water temperature; ammonia result; nitrite result; nitrate result; pH result; feeding level; weather; and filter cleans and equipment changes. Enter spring tests under the same ten fields every year, and compare this spring's…
Give every tetra batch one log entry with exactly eleven fields: spawning date; pair or group; water conditions before spawning; egg location; hatch date; first free-swimming date; estimated fry count; foods offered; water changes; losses and deformities; and weekly size estimate. Open the entry on spawning day,…
Keep one equipment log for the goldfish setup, with exactly five fields for every entry: item, date bought, date installed, faults and odd behaviour with dates, and planned replacement date. Enter heaters, light units and filter parts as separate lines, note each rattle, temperature drift or stall against the item…
